ウクライナオデッサからメール

Good Thursday, How are you today? Thanks a lot of kind words to me in your letter,

telling me about your blog-I can't open-here very old computers!

I never travel to another countries,but dream.

I like comedy & romantic movies. what about you? I don't have boyfriend,here mostly all men at war.

I had a boyfriend,but he died at war 1,5 years ago.I will be happy to have family with kids & marry with man older than me.

Today no lessons in college,I write you letters from library,because no private computer at home.

I had before a small smartphone,but change it for food 5 month ago. Now we use old nokia together with mom,Ha-ha!

Soon I will finish institute. But here very hard to find any job,all from war here.I know about sushi from TV programs,

but never eat sushi,because sushi restaurants very expensive here.

I don't have boyfriend now,here all men at war.

I have good news: yesterday evening was stopped fire between Ukraine & Russia.

We have big hope that this time it will be true words from Presidents & peace will come,

Because this "stop war" was many times,but it was only words...

I want to tell you that from yesterday really was no hear shots, bombings.

But situation with electric, water & mostly with food still very, very hard. It is very difficult to sell something or to exchange for food, many have no money, and rich people left from Ukraine.

It's a pity that without meat, meat here terrible expensive long ago. When was no war we could buy meat, not often, but we could.But we are happy that we have some vegetables.

Usually here very cold winter, normally-25, - 30, much snow,now autumn +10.

I like to cook very much! Today, I will tell you how to cook borsch:take piece of beef to weld in water, then to cook there potatoes, carrots, cabbage,

it is a little haricot, then we add a little tomato paste, salt, parsley.

Give a borsch very hot with sour cream and garlic. Its very good for health hot dish & you not catch a cold.

Of course garlic isn't good for kisses, but when we will meet I cook borsch for us & we will eat garlic together & then could easy kiss...

May be on today will come my friend Maria.I send you summer photo with my friend Maria.

She lost family at war & have no possible to live in this hard war period,

I was invite her for dinner. I wish you happy, warm day.

Two years have passed since I moved to a developed country

ほらよ。

https://anond.hatelabo.jp/20171014071350

I am working as an engineer in the IT area, but I managed to hold it for some 2 years.

I do not have confidence yet, and I feel even more confident about my confidence for the rest of my life, the excellence of my colleague.

If I do not desperately do it I am working everyday with feelings that it is not amusing even if I receive a notification outside the fighting strength.

Still, in Japan, I think that Japan has much better skill than CTO in that area.

In the future I thought that if I could return to Japan and contribute to the Japanese society, Japan that is visible from the outside is bad.

What is bad, first aspect of politics.

Politics

The point that democracy is not fully functioning against the fact that there are stupid citizens who blind the LDP, such as Abe's descent.

That other party is also not good. Hope party? What is that lady like that disciple of Ru Ooshiba? Rou Koike?

The more you do not have it, the stupid will be clouded in katakana and psychology. You idiots, you guys say this. I love Katakana anyway, I love psychology, 100% I do not say big things. What is Y's Spending. Do not fix what you normally call katakana.

Since the political system is over in the first place, I think that it is the cause of failure of not receiving popular people, especially elderly people, only short-term and useless policies absolutely. So we will not attack only the LDP.

It is too fatal that politics is not rational and it is impossible to include the policy that should be done. Because it ends with poppiness if I can not vote.

Unfortunately, the trend of changing the political system probably will not happen if it fails.

In recent decades, politicians have accelerated the declining birthrate and aging society to a distortion with outlook on the preferential treatment for the elderly + measures against the declining birthrate.

The decline in Japan's birthrate and birthrate is partly spontaneous, but the world's low birthrate and aging society is not caused by natural phenomena.

There is not any future that putting all the energy to surrender the tax to the old man by tax free over medical care. It was already late when we were discussing whether a large amount of tax would be used due to politicians' old elderly votes or ten years ago, so it was already late, we have not corrected the orbit again so far I am going to politate on the same route.

An aged politician does not think about a short-circuiting policy, the future. Citizens delight in the immediate economic policy.

Grass grows now, as the nation 's collapse has become a reality.

If the declining birthrate and the aging population advanced at this pace as it is, the Japanese boat will sink in 20 years. Two years ago I thought I would have 30 years.

I gave up completely to Japan's politics. Defeated entertainment is not funny. I'm saying that it is japanese, but I do not dislike it. To give up means to accept failures.

Next is the aspect of business.

business

Did you have a business anywhere other than bidding? I do not have pieces of creativity. There is no further ethics.

What is it, Mercari or DeNA or moral business or something is a social sin. I just confused society, did not I? The country and the country came to know not ethics.

Ethics of the Japanese are lower than the Japanese think.

Although I derail for a while, accident happens in front of my eyes, the idiots who take pictures with smaho are not minorities at all Nationality is bad.

Even though there is service only where money is involved, do not say hospitality as if it were the national character of the Japanese.

It is not a minority to be a completely individualist society and people are troubled and help people.

At this time new creative business is born from one to the next. It is at an unthinkable pace in Japan. Of course, there are many doubtful businesses as to whether it will become money, but it is better than Japanese society where there is no brain except copying the business of another company at all.

So almost no company wants to work in Japan.

And the fall of the company. Almost no international competitiveness. Even large corporations will be crushed.

With this aging birthrate and declining birthrate, you can not contribute even to domestic demand with the elderly who can not see the future if it is full of old people.

There are no people with a declining birthrate. It seems that young people are supporting the LDP by thinking positively as being a seller's market completely.

There is only one person who is not merely a policy of an aging population declining birthrate. Your future is pitch dark.

Were I so stupid as to whom I thought of going back to Japan? What? It is certain that at least the field of view and experience has been much lower than it was now.

If I see myself two years ago, I feel mercy only now.

Indeed it is visible that it will collapse in another few decades Indeed it will not be possible to return to Japan.

Why do I have to board a sinking ship? Parents are the only team to surrender, only you are to protect yourself.

Originally I decided not to make children from the uncertain future of society, not myself. I think that choice was right.

Politician Now, if you are not stupid, it means that you are doing intentional bankruptcy activities.

It is good that you are only interested in being inspected. I do not know anymore.

At the very least, please try to make Japanese citizens work in the world. If the hurdle of labor visa goes down, then you will be able to do it if you have English proficiency.

I had a lot of hardships. Although it is inferior to native, I am working without problems.

Oh, I wanted to go back to Japan. . .

The way to Take the place of a fabulous Personal computer Computer keyboard

Changing a new laptop computer keyboard will be difficult regarding someone considering that it is without a doubt defined to become tech function though really isn't. Just by subsequent a number of easy steps one could replace the actual laptop key pad comfortably.

1st step is actually to ensure that you will have powered down the vitality and taken off the particular battery. Equally you might want to unplug this from switchboard to prevent just about any hassle. An individual will be through with the software, you ought to start all the laptop computer along with remove lots of the screws behind that. Even if various mobile computer models possess different screws but it is simple to choose the anchoring screws in order to them all.

Typically, all the keyboards are generally devote a plastic material sheet which happens to be screwed throughout the equipment. For that reason right here anyone must also get rid of the screws in an effort to get rid of those plastic-type sheets. Any time one can find absolutely no plastic-type material sheets after that probably right now there may be some clamps which is often deleted readily.

An individual will be through with the actual taking away the plastic material sheets right now there may be some cosmetic outstanding on the computer keys. All of these plastic material bits has to be removed cautious and it could be completed any help in various cosmetic choose and tooth find. It is actually highly recommended will not use almost any needle which is able to really problems another aspects of machines.

At this time you might be through with just about all screws inside the back, you need to take away the screws towards the top because in some laptop or pc units often times there are anchoring screws beginning which should end up being deleted before you really replace all the computer keys. When most of anchoring screws really are eliminated, you will see the laptop computer keyboard is something related to any thin knowledge lead that is straightaway that come with the actual motherboard best in the bottoom. To eliminate any laptop correctly, feel free to use the equivalent enamel pick to enable you to raise the plastic-type connectors which you'll find storing with this knowledge lead. You will see of the fact that entirely computer keyboard can be free professionals who log in very easily lift that up.

You will have successfully carried out the most important part and it's the moment you are able to replace that classic laptop or pc computer keyboard while using unique 1. Very first thing earliest, take the popular computer hp laptop keyboard out from the plastic page and remedy a repair anywhere between that cosmetic fittings that are existing for the chief panel. You will need to ensure that your comprehensive brand new keyboard set is set. These days include the info line very carefully. You need to use similar choose anyone used formerly to try the equivalent. Be sure that the entire openings as well as clamps are straight aligned along with the mess space as a result for all those securing that screws repeatedly, it is possible to finished the software as necessary. Lastly refasten your current laptop computer keyboard within the top and also if you wish to remove any specific cosmetic articles replicate the equivalent option a person achieved it up to now.

Now restricted most of the screws from again and get that laptop's solar battery funding the area to enable you to observe regardless if your own laptop have been replaced instead systematically or even in no way. An individual will be through with tensing all the screws, start up your current laptop considering the fact that a person hear numerous beeps in the beginning then very likely you might want to eradicate all of the procedures once again. See a BIOS through important F2 or DEL button to be sure of whether or not keyboard is actually tracked down to be had and not even.

Article 14 the mobile phone will know the battery skills

If users want to prolong battery the efficient use of the time, in addition to the quality of the charger to have the guarantee, the right skills and charging is essential, because of low quality charger or wrong charging methods would affect battery time and life cycle, the following is about to charge skills:

1. The battery before they leave the factory, manufacturers were activated processing, and the charge, so the battery are more electricity, my friends say battery charging adjustment period in accordance with the time, standby still seriously insufficient, assuming that the battery is really quality goods battery of words, this kind of circumstance should extend the setting and then 3 ~ 5 times fully charge and discharge.

2. If new phone is lithium ion battery, so before 3 ~ 5 times charging commonly known as adjustment period, should be charged more than 14 hours, in order to ensure that the fully activate lithium ion activity. The lithium ion battery no memory effects, but have very strong sui sex, should give full activated PANASONIC CGR-D220 Battery, to guarantee the use of after can reach the right performance.

3. Some automation intelligent quick charger when instructions lights change, said only full of 90%. The charger will automatically change with slow charge will batteries. Best will use after batteries, otherwise, it will shorten use time.

4. Before charging and discharging lithium battery does not need special, but will not discharge damage to the battery. As far as possible when charging at the slow ChongChongDian, reduce the way quick charge; Time don't more than 24 hours. The battery after three to five times fully recharge cycles of internal after chemical will be all "activate" to achieve the best use effect.

5. Please use the original or the reputation of the good brand charger, li-ion battery to lithium battery charger with special, and follow the instructions, otherwise, it will damage to the battery, and even dangerous.

6. Have many users often in charge still leave her cell phone, actually such will be very easy to PANASONIC CGA-S101E/1B Battery damage the service life of the mobile phone, because in charge of the process, the circuit boards of mobile phone can calorific, if this time more exotic phone, may produce instant backflow current, internal parts to mobile phone damage.

7. The battery life depends on the number repeatedly charging and discharging, so should try to avoid more battery electric charge when, this will shorten battery life. Cell phone time more than 7 days, supposed to completely discharge the cell phone battery, enough electricity before use.

8. The cell phone battery have self-discharge, need not when the nimh batteries will press the residual capacity every day, about 1% of the discharge, lithium battery every day to 0.2% ~ 0.3% discharge. In for the battery, try to use the special socket, don't will the home appliance such as the Shared and the TV charger socket.

9. Though the phones in the network coverage area, but in the cell phone charge, cell phones have been unable to accept and call. At this time, can use of the mobile phone is not transfer function, will be transferred to the mobile phone side of fixed telephone in order to prevent calls lost, this kind of method for mobile phone is not in the network coverage of the area or weak signal and temporarily unable to the applicable also.

10. Don't will be exposed to high temperature or cold PANASONIC DMW-BCG10E Battery , as the dog, should not put the phone on the car, and the sun blazed through the; Or get air conditioning room, in air conditioning to be blown continuously place. When charging, the battery is a little heat is normal, but can't let it what the high temperature "suffer". In order to avoid the happening of this kind of circumstance, had better be in charge at room temperature, and don't cover anything on the mobile phone.

11. Nickel cadmium (N iCd) before the battery must ensure that the batteries are no electricity, recharging the battery must ensure that sufficient electricity after.

12. If the cell phone battery placed too long and not use, the best maintenance department to cell phones to the application for a live processing, also can use a constant dc voltage is the voltage adjustment for 5 ~ 6 V, current 500 ~ 600 mA reverse connect battery. Note that a touch namely release, the most repeated three times can, through such treatment after another, with the original adapter to "adaptation" charge.

13. Charge is not as long as possible, to no protection circuit batteries that should stop after charging, or the battery will with fever or overheating impact performance.

14. Lithium ion battery must choose special charger, otherwise may not reach the saturated state, affect their performance. Charging completes, should avoid to place in charger on more than 12 hours or more, long-term need not when should make a battery and cell phone separation.

Portable electronic equipment battery technology

1, about the trickle charge, rapid charging and stable battery charging algorithm

According to the energy requirements of the final application, a battery may contain up to 4 lithium ion or lithium polymer battery core, its configuration will have a variety of change, at the same time with a mainstream power adapter: direct adapter, USB interface or car charger. Remove the core quantity, core configuration or power adapter type difference, the battery has the same charge characteristics. So they charge algorithm. Lithium ion and li-ion polymer battery best charging algorithm can divided into three phases: trickle charge, rapid charging and stable charge.

trickle charge. For depth discharge core to charge. When core voltage in less than about 2.8 V, use a constant 0.1 C of the current charging for it.

fast charging. Core voltage trickle charge more than the threshold, improve the charging current rapid charging. Fast charging current should be lower than 1.0 C.

stable voltage. In the fast charging process, once the core 4.2 V voltage, stable voltage phase began. This is through the minimum charge current or timer or of the two joint to interrupt charge. When the minimum current below about 0.07 C, can interrupt charge. The timer is to rely on a default to trigger the timer interrupt.

Advanced battery charger with additional security function normally. For example, if the core temperature exceeds the given window, usually 0 ℃-45 ℃, charge will be suspended.

Remove some very low-end equipment, now on the market/li-ion polymer lithium ion battery solutions are integrated with the outer components or, in accordance with the characteristics of the charging to charge, this is not just to get better effect charge, but also for safety.

lithium ion/polymer battery charge is an example of applications-double input 1.2 A lithium battery charger LTC4097

LTC4097 can be used to exchange adapter or USB power supply for single quarter/polymer lithium ion battery. Figure 1 for double input 1.2 A lithium battery charger LTC4097 schemes. It USES constant current/constant voltage algorithm charging, from exchange adapter power charge, programmable filling up to 1.2 electric current A, and with USB power can be as high as 1 A, at the same time, automatic detection in each input voltage whether there. This device also provide USB the current limit. Applications include PDA, MP3 players, digital camera, light portable medical and test equipment and big color cellular phone. The performance characteristics: no external micro controller charging termination; The input power automatic detection and choice; Through the resistance from the exchange of charging adapter input can be as high as 1.2 A programming charge current; The resistance of programmable USB charging current is up to 1 A; 100% or 20% USB charging current set; The input power output and existing bias NTC (VNTC) pin as a 120 mA drive ability; NTC thermistors input (NTC) pin for temperature qualified charged; Pre-settings battery voltage with floating plus or minus 0.6% accuracy; Thermal regulation maximize charge rate and free hot air LTC4097 can be used to exchange adapter or USB power supply for single quarter/polymer lithium ion battery. The use of constant current/constant voltage algorithm charging, from exchange adapter power charge, programmable filling up to 1.2 electric current A, and with USB power can be as high as 1 A, at the same time, automatic detection in each input voltage whether there. This device also provide USB the current limit. Applications include PDA, MP3 players, digital camera, light portable medical and test equipment and big color cellular phone.

2, lithium ion/polymer battery scheme

Lithium ion/polymer battery charge scheme for different number of core, core configuration, and power types are different. At present mainly have three main charging scheme: linear, Buck (step-down) switch and SEPIC (booster and step-down) switch.

2.1 linear scheme

When the input voltage in big with the charger with sufficient clearance of core after opening voltage, it is linear scheme, especially 1.0 C fast charging current than 1 A big too much. For example, MP3 players usually only one core, capacity from 700 to 1500 mAh differ, full charge voltage is open 4.2 V. MP3 player power is usually the AC/DC adapter or USB interface, the output is the rule of 5 V; At this time, the linear scheme is the most simple, most charger of the efficiency of the scheme. Figure 2 shows for lithium ion/polymer battery solution linear scheme, basic structure and linear voltage neat device.

linear scheme charger application examples-double input Li + charger and intelligent power source selector MAX8677A

MAX8677A is double input USB/AC adapter linear charger, built-in Smart Power Selector, used for rechargeable single quarter by Li + batteries portable devices. The charger integration of the battery and the external power source and load switch charging all the power switch, so that no external MOSFET. MAX8677A ideal used in portable devices, such as smart phones, PDA, portable media players, GPS navigation equipment, digital camera, and digital cameras.

MAX8677A can work in independent USB and the power input AC adapter or two input either one of the input. When connecting external power supply, intelligent power source selector allows the system not connect battery or can and depth discharge battery connection. Intelligent power source selector will automatically switch to the battery system load, use the system did not use the input power supply parts for battery, make full use of limited USB and adapter power supply input. All the needed electric current detection circuit, including the integration of the power switch, all integration in the piece. DC input current highest limit can be adjusted to 2 A and DC and USB input all can support 100 mA, 500 mA, and USB hung mode. Charge current can be adjusted to as high as 1.5 A, thus support wide range of battery capacitive. Other features include MAX8677A thermal regulation, over-voltage protection, charging status and fault output, power supply good surveillance, battery thermistors surveillance, and charging timer. MAX8677A using save a space, hot enhanced, 4 mm x 4 mm, 24 of the pins TQFN encapsulation, regulations, work in exceptional temperature range (40 ~ + 85 ℃).

2.2 Buck (step-down) switch scheme

When A 1.0 C of the charging current more than 1 A, or the input voltage of the core than with high voltage open many, Buck or step-down plan is A better choice. For example, based on the hard drive in the PMP, often use single core lithium ion battery, the full of open is 4.2 V voltage, capacity from 1200 to 2400 mAh range. And now PMP is usually use the car kit to charge, its output voltage in a 9 V to 16 between V. In the input voltage and battery voltage is the voltage difference between high (minimum 4.8 V) will make linear scheme lowers efficiency. This kind of low efficiency, plus more than 1.2 A 1 C fast charging electric current, have serious heat dissipation problems. To avoid this kind of situation, will the Buck scheme. Figure 3 for lithium ion/polymer battery charger scheme Buck diagram, basic structure with Buck (step-down) switching voltage regulators completely the same.

2.3 SEPIC (booster and step-down) switch scheme

In some use of three or four lithium ion/polymer core series equipments, charger of the input voltage is not always greater than the battery voltage. For example, laptop computers use 3 core lithium ion battery, full charge voltage is open 12.6 V (4.2 V x3), capacity is 1800 mAh to 3600 mAh from. Power supply input or output voltage is 1 6 V AC/DC adapter, or is car kit, the output voltage in a 9 V to 16 between V. Apparently, the linear and Buck solutions are not for this group of batteries. This is about to use SEPIC scheme, it can in the output voltage is higher than when the battery voltage, can be in the output voltage less than when the battery.

3, and power detection algorithm is proposed

Many portable products use voltage measurements to estimate the remaining battery power, but the battery voltage and surplus power relationship but will with the discharge rate, temperature and battery aging degree of change, make this kind of method can top 50% margin of error. The market for longer to use product demand unceasingly strengthens, so the system design personnel need more accurate solution. Use capacity check plan come to measure battery or consumption of electricity, will be in a wide range of application power to provide more accurate estimate of the battery power.

3.1 power detection algorithm is one of the examples of application, function complete list, double the battery portable battery application design

power detection principle. Good capacity check plan at least to have battery voltage, temperature and battery electric current, measuring method; A micro 9 a; And a set of and the verification of the punishment power detection algorithm is proposed. Bq2650x and bq27x00 is full capacity check program function, with a measuring voltage and temperature of the digital converter (ADC) and a measuring electric current and charging sensor the asp. These capacity check plan also has a microprocessor, is responsible for the implementation of the Texas instruments power detection algorithm is proposed. The algorithm can compensate the lithium ion battery life.low self-discharge, aging, the temperature and discharge rate, and other factors. Chip embedded microprocessor as host system processor save these calculation burden. Capacity check program can provide remaining power state information, bq27x00 series products also offer surplus can Run Time (Run Time to Empty) host may at any Time to capacity check plan these information query, then LED indicator light through or displays will inform the user battery. Capacity check meter is very easy to use, the system processor need only configuration 12 C or HDQ communication drive can.

The battery circuit description. Figure 4 (a) can be used for identification of IC functions with typical application circuit batteries. According to the use of IC testing program is different, the battery needs to have at least three to four outside the terminal.

VCC and BAT pins will even to the battery voltage, so that for, C power and the battery voltage measurement. The battery is connected a grounding resistance smaller detection resistors, let capacity check meter high impedance SRP and SRN input can monitor sensor resistance on both ends of the voltage. Through testing the current flows through a resistor can be used to judge the battery or release the amount of electricity. Designers choose detection resistance value must be considered when resistance on both ends of the voltage can't more than 100 mV, low resistance may be more hours in current errors. Circuit board layout must ensure that SRP and SRN to testing from as close as possible to the connection of the resistor sensor resistance end; In other words, they should be the Kelvin attachment.

HDQ pin need external and resistors, this resistance should be located the host or the main application, such capacity check plan to the battery and portable devices when sleep function enable connection broken. Advice and resistance choose 10 k Ω.

battery identification. A low cost WeiMao batteries are getting more and more serious, these cells may not contain OEM requirements of security protection circuit. So, genuine battery may contain figure 4 (a) shows the appraisal circuit. When to identify the battery, the host to contain IC (bq26150, the function is cyclic redundancy check (CRC)) issued the battery packs a ask value (challenge), the CRC will contain battery according to this inquiry value and, in the building of the IC in CRC polynomial calculation the CRC value. CRC is based on the host of command and IC secret in the query of the definition of the CRC polynomial completed, the host in CRC values calculated with the calculation result of well battery comparison to identify the appraisal success.

Once the battery through the appraisal, bq26150 will issue commands to ensure that the host and quantity test plan of material lines between normal communication. When the battery connection interruption or to connect, the whole the identification process will be repeated again.

double the battery application. Figure 4 (b) for use bq26500 support double the typical application of lithium ion battery circuit. In order to support more battery, and this circuit is adding a adjustable regulators. Capacity check millions of BAT pin and the bottom of a battery anode linked to complete the variable voltage measurement of the battery.

Host to be able to read capacity check plan of variable voltage measurement battery, to make sure the end of discharging threshold and charging terminate threshold. As for the remaining state power (RemainingStateofCapacity), do not need to read can use directly.

The above bq2650x and bq27x00 etc capacity check plan provides the battery manufacturer a simple to use options, this scheme L [just measuring battery voltage to be precise, so these capacity check plan can be applied to various battery framework, and can support the battery identification and double the battery application '

3.2 power detection algorithm is an example of applications another, can apply to all kinds of general voltmeter new IC.

Today's many manufacturers can provide a variety of voltmeter IC,, the user can choose the suitable function device, to optimize the product price. Use voltmeter measurement of storage battery parameters, the separate architecture allows users in the host custom power measurement algorithm within. Eliminating embedded processor battery cost. On this to Dallase semicconductor company called cases of DS2762 chip for typical analysis. A new separate voltmeter IC, its structure see chart 5 (a) below.

DS2762 application characteristics

DS2762 is a single quarter of lithium battery voltmeter and protection circuit, integrated into a tiny 2.46 mm x 2.74 mm inversion of packaging. Due to internal integration for power detection of high precise resistance, this device is very save a space. It is the small size and incomparable high level of integration, for mobile phone battery and other similar handheld products, such as PDA, etc, are all very ideal. Integrated protection circuit continuously monitoring the battery voltage, over voltage and flow fault (charging or discharge period). Different from the independent protection IC, DS2762 allow main processor surveillance/control protection FET conduction state, such, can DS2762 through the protection of the power system and the control circuit implementation. DS2762 can also charge a battery consumption has depth, when the battery voltage within three V, provide a limit of the charging current recovery path.

DS2762 accurate monitoring battery current, voltage and temperature, the dynamic range and resolution of common satisfy any mobile communication product testing standards. The measurement of current for internally generated when the integral, realize the power measurement. Through the real-time, continuous automatic disorders correct, the precision of power measurement can be increased. The built-in measuring resistance due to eliminate manufacturing process and temperature and cause resistance change, further improve the precision of the voltmeter. Important data stored in 32 bytes, can add the lock EEPROM; 16 bytes of SRAM are used to keep dynamic data. And DS2762 all communication all through the 1-Wire, more communication interface node, minimize the battery and the connection to the host. Its main features for; Single quarter of lithium battery protector; High precision current (power measurement), voltage and temperature measurement; Optional integrated 25 m Ω measuring resistance, each DS2762 after fine-tuning alone; 0 V battery restore charge; 32 bytes can lock EEPROM, 16 bytes SRAM, 64 a ROM;
