Although I am a college college student but recently I went to the test site of the Futamata River by the license renewal I was suddenly inverse of an Afro hair woman like Esperanza Spalding but my hair style was so beautiful but my face was so beautiful that I exchanged the tension and exchanged the line that day Although I broke up but the message arrived and it was invitation of the gong consomme so it got even more tension Soon after talking to the department's friends I gathered members and gathered at the private room pub in Ikebukuro yesterday Esperanza Spalding Because I got urgent, I joined up late, so I started drinking with men and women 3, for the time being, for the time being I started to drink 4 girls 3 and the situation of the three girls was obviously crazy and everyone's cute but the face is cute, but the behavior has been consistently suspicious and constantly dull Absolutely by moderation We are not trying to fit together what the matter These children are becoming uneasy but I come with pins at once so that they are all virgins and not quite accustomed to men so I think they are getting nervous so tense If that happens, the men are reincarnated again in the meaning that it is exciting but even if we struggle hard we can not relax their tensions, oh well, if you are confused with what you've done already Unexpected development One of three visited us to take out the booklet from the bag as a matter of fact and began to distribute it to our male team and it seems that if we look closely it is a group name that we have never heard of as an admission guide for emerging religion but we are staggering as to what I got to say that they started to recruit us seriously and spirited about the wonder of the cult and the greatness of the guru and the depth of history and the appreciation of the interests But all three of the girls changed their hands a little while ago and now we are relaxing and we have to stay silent for the time being silent as soon as we go into time like hell and fall apart suddenly the branch of the private room suddenly As the girls screamed at once with all the girls shouting "Guru-sama!" As they all looked at, look at them and wear a rag in the whole body and gods of Afrohair with a golden stick stand standing and see well with Esperanza Spalding While placing a nice smile on the placard, "There is a great success! Although it was all written as it was written as it was all It was a genuine thing seemed to be the entrance guidance of the cult but if it asked what you want to do is to cooperate with friends of the design major, The greetings and the history of the cult and so forth are written carefully and photographs and illustrations are abundantly used and the layout is also getting stuck. I thought that this wasteful energy pouring condition is usually thoughtful but usually they are beauty and theater theater circle Doing it and it seems to be an actor fellow there, just a while ago I came up with this fake religion Dokkari and looked for a target It seemed me that I was captured in the truth so it seems that three of my friends took care of the collaboration but since I was made a solicitude Girls who were suspiciously behaviorally suspicious because they got tension relaxed at once Espana spallding was also funky at the highest Espana Spalling was also funky so I was already enjoying it too much I drunk quite drinking I felt memory flew from the way I seemed to have collapsed apparently but when I woke up 4 men were at an internet cafe and everyone remembered too much I am not sure, girls are not found anywhere Even if I line it to Esperanza Spalding I will not be read Alright, while thinking that gossip with beauty students is dangerous, I wrote this in a private room of a net cafe now.


私は大学生ですが、最近は二代目川の試験場に免許更新で行きました。私は突然エスペランサ・スパルディングのようなアフロ髪の女性とは逆でしたが、私の髪型はとても美しいですが、私の顔はとてもきれいでしたその日に緊張を交わしてその日のラインを交換しましたが、メッセージが届きましたが、それはゴングコンソムの招待で、もっと緊張しました。すぐに部署の友人と話した後、私はメンバーを集め、池袋プライベートルームパブに集まりました昨日エスペランサ・スパルディング緊急事態になったので、私は遅く入社したので、当分の間、私は男女3人で飲み始めました。私は4人の女の子3を飲み始めました.3人の女の子の状況は明らかに狂っていました。誰もがかわいいが、顔はかわいいですが、その行動は一貫して疑わしく、常に鈍いです。絶対に適度には私たちは一緒に取り組もうとしていません。不安ですが、私は一度にピンを持ってくるので、彼らはすべて処女であり、男性にはあまり慣れていないので、彼らは緊張していると思います。そのようなことが起きれば、男性は再び興奮するという意味で生まれ変わりますあなたがすでに行ったことと混同している場合は、緊張を緩和することはできません。予期せぬ開発3人のうち1人が、実際にバッグから小冊子を取り出して、男性に配布し始めました私たちが密接に見ると、それは新興宗教入学ガイドとしては聞いたことのないグループ名ですが、私たち真剣私たち募集し始めると言うことを驚かせていますカルトの偉大さと歴史の深さと利益尊重しかし、少女の3人はすべて少し前に手を変え、今はリラックスしているので、私たちは静かなまま静かにしなければならないすぐw地獄のように時間が掛かり、突然個室の枝が崩壊する突然、女の子たちが一瞬に叫んで「女達さま」と叫んだ。彼らが見ているように、それらを見て、全身にぼかしをかけ、アフロヘアの神々を金色の杖で立って立て、Esperanza Spaldingとよく会ってください。プラカードに素敵な笑顔を浮かべている間、「大成功です!それはすべて書かれたようにすべて書かれていました。それはカルトの入口指針と思われる本物のものでしたが、あなたがしたいことを尋ねるなら、デザイン専攻の友人と協力することです、挨拶歴史写真イラスト豊富に使われてレイアウトも詰まっているこの無駄エネルギー注ぎ込みは普通思慮深いと思っていましたが、通常は美しさと演劇劇場サークルですそこの俳優になってください、ちょっと前に、私はこの偽の宗教のDokkariを思いついて目標を探しました。私は真実に捕らえられたようでしたので、3人の友人が協力してくれたようです私は恋人となったので、疑わしい行動が疑わしい女の子たちは緊張感を緩和していたので、Españaも最高のファンキーであった。Spallingもファンキーだったので、私はすでにそれを楽しんでいた。私は明らかに崩壊したようでしたが、私が目を覚ましたときインターネットカフェに4人の男性がいて、みんながあまりにも多くを思い出していました。私はよく分からない、女の子はどこにも見られません。私はEsperanza Spaldingに行けても、美容師とのゴシップ危険だと思って、ネットカフェプライベートルームにこれを書きました。


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
