4 Ouline This is a baery proec soluion IC which is inegraed wih buil-in he proecion IC o use a lihium ion/lihium polymer secondary baeries developed for 1-cell series and Dual-Nch MOSFET. I funcions o proec he baery by deecing overcharge, overdischarge, discharge overcurren, charge overcurren and oher abnormaliies as urning off inernal Nch MOSFET. The proecion IC is composed of four volage deecors, shor deecion circui, reference volage sources, oscillaor, couner circui and logical circuis. The COUT pin (charge FET conrol pin) and DOUT pin (discharge FET conrol pin) oupus are CMOS oupu, and can drive he inernal Nch MOSFET direcly. The COUT oupu becomes low level afer delay ime fixed in he IC if overcharge is deeced. The DOUT oupu becomes low level afer delay ime fixed in he IC if overdischarge, discharge overcurren or shor is deeced. On overcharge sae, if he DD volage is less han he overcharge release volage, he COUT oupu becomes high level afer delay ime fixed in he IC. On overdischarge sae, if he volage of he baery rises more han he overdischarge deecion volage wih connecing he charger, he DOUT oupu becomes high level afer delay ime fixed in he IC. Charging curren canbesuppliedohebaerydischargedupo0. Once discharge overcurren or shor have been deeced, if he sae of discharge overcurren or shor is released by opening he loads, he DOUT oupu becomes high level afer delay ime fixed in he IC. On overdischarge sae, he supply curren is reduced as less as possible. Once charge overcurren has been deeced, he sae of charge overcurren is released by opening he charger and seing he load

12 Operaion 1. Overcharge deecor (D1) The D1 moniors DD pin volage during charge. In he sae of charging he baery, i will deec he overcharge sae of he baery if he DD erminal volage becomes higher han he overcharge deecion volage(typ ). And hen he COUT erminal urns o low level, so he inernal charging conrol Nch MOSFET urns OFF and i forbids o charge he baery. Afer deecing overcharge, i will release he overcharge sae if he DD erminal volage becomes lower han he overcharge release volage(typ ). And hen he COUT erminal urns o high level, so he inernal charging conrol Nch MOSFET urns ON, and i acceps 새 charge he baery. When he DD erminal volage is higher han he overcharge deecion volage, o disconnec he charger and connec he load, leave he COUT erminal low level, bu i acceps o conduc load curren via he paraciical body diode of he inernal Nch MOSFET. And hen if he DD erminal volage becomes lower han he overcharge deecion volage, he COUT erminal urns o high level, so he inernal Nch MOSFET urn ON, and i acceps o charge he baery. The overcharge deecion and release have delay ime decided inernally. When he DD erminal volage becomes higher han he overcharge deecion volage, if he DD erminal volage becomes lower han he overcharge deecion volage again wihin he overcharge deecion delay ime(typ. 1.00s), i will no deec overcharge. And in he sae of overcharge, when he DD erminal volage becomes lower han he overcharge release volage, if he DD erminal volage backs higher han he overcharge release volage again wihin he overcharge release delay ime(typ. 16ms), i will no release overcharge. The oupu driver sage of he COUT erminal includes a level shifer, so i will oupu he - erminal volage as low level.the oupuypeofhecout erminal is CMOS oupu beween DD and - erminal volage. 2. Overdischarge deecor (D2) The D2 moniors DD pin volage during discharge. In he sae of discharging he baery, i will deec he overdischarge sae of he baery if he DD erminal becomes lower han he overdischarge deecion volage (Typ ). And hen he DOUT erminal urns o low level, so he inernal discharging conrol Nch MOSFET urn OFF and i forbids o discharge he baery. Once overdischarge has been deeced, overdischarge is released and he DOUT oupu becomes high level, if he volage of he baery rises more han he overdischarge deecion volage wih connecing he charger, or more han he overdischarge release volage wihou connecing he charger. Charging curren is supplied hrough a parasiic diode of Nch MOS FET when he DD erminal volage is below he overdischarge deecion volage o he connecion of he charger, and he DOUT erminal eners he sae which can be discharged by becoming high level,and urning on Nch MOS FET when he DD erminal volage rises more han he overdischarge deecion volage

13 When he baery volage is abou 0, if he charger volage is higher han he minimum operaing volage for 0 charging (Max. 1.2), he COUT erminal oupus high level and i acceps o conduc charging curren. The overdischarge deecion have delay ime decided inernally. When he DD erminal volage becomes lower han he overdischarge deecion volage, if he DD erminal volage becomes higher han he overdischarge deecion volage again wihin he overdischarge deecion delay ime (Typ. 20ms), i will no deec overdischarge. Moreover, he overdischarge release delay ime (Typ. 1ms) exiss, oo. All he circuis are sopped, and afer he overdischarge is deeced, i is assumed he sae of he sandby, and decreases he curren (sandby curren) which IC consumes as much as possible. (When DD=2, Max. 0.5uA). The oupu ype of he DOUT erminal is CMOS oupu beween DD and SS erminal volage. 3. Discharge overcurren deecor, Shor deecor (D3, Shor Deecor) In he sae of chargable and dischargabe, D3 moniors he volage level of - pin. If he - erminal volage becomes higher han he discharging overcurren deecion volage (Typ ) by shor of loads, ec., i will deec discharging overcurren sae. If he - erminal volage becomes higher hen shor deecion volage (Typ. 0.9), i will deec discharging overcurren sae, oo. And hen he DOUT erminal oupus low level, so he inernal discharging conrol Nch MOSFET urns OFF, and i proecs from large curren discharging. The discharging overcurren deecion has delay ime decided inernally. When he - erminal volage becomes higher han he discharging overcurren deecion volage, if he - erminal volage becomes lower han he discharging overcurren deecion volage wihin he discharging overcurren deecion delay ime (Typ. 12ms), i will no deec discharging overcurren. Morever, he discharging overcurren release delay ime (Typ. 4ms) exiss, oo. The shor deecion delay ime (Typ. 400us) decided inernally exiss, oo. The discharging overcurren release resisance is buil ino beween - erminal and SS erminal. In he sae of discharging overcurren or shor, if he load is opened, - erminal is pulled down o he SS via he discharging overcurren release resisance. Andwhenhe- erminal volage becomes lower han he discharging overcurren deecion volage, i will auomaically release discahrging overcurren or shor sae. if discharging overcurren or shor is deeced, he discharging overcurren release resisance urns ON. On he normal sae (chargable and dischargable sae), he discharging overcurren release resisance is OFF. 4. Charge overcurren deecor (D4) In he sae of chargable and dischargable, D4 moniors he volage level of - pin. If he - erminal volage becomes lower han charging overcurren deecion volage (Typ ) by abnormal volage or curren charger, ec., i will deec charging overcurren sae. And hen he COUT erminal oupus low level, so he inernal charging conrol Nch MOSFET urn OFF, and i proecs from large curren charging. I release charging overcurren sae if he abnormal charger is disconneced and he load is conneced. The charging overcurren deecion has delay ime decided inernally. When he - erminal volage becomes lower han he charging overcurren deecion volage, if he - erminal volage becomes higher han he charging overcurren deecion volage wihin he charging overcurren deecion delay ime (Typ. 16ms), i will no deec charging overcurren. Morever, he charging overcurren release delay ime (Typ. 4ms) exiss, oo

14 5. Overvolage charger deecor By monioring charger volage beween DD erminal and - erminal, and when he volage becomes higher han over volage charger deecion volage, COUT oupu becomes low level and inernal Nch MOSFET is urned o OFF. And when he volage becomes lower han over volage charger release volage, COUT oupu becomes high level and inernal Nch MOSFET is urned o ON. Please noe ha he larger value of R2, he larger deecion volage. There is no delay ime of deecion and release for his funcion
