Advanced Analog Technology, Inc. AAT8641 Series Product information presented is current as of publication date. Details are subject to change without notice ONE-CELL LI-ION BATTERY PROTECTION IC FEATURES GENERAL DESCRIPTION z Ideal for One-Cell Rechargeable Li-Ion Battery Packs z High Accuracy Voltage Detection z Low Current Consumption: The AAT8641 series are designed for the protection of one-cell rechargeable Li-Ion battery pack against over charge, over discharge, over current and short circuit. They use CMOS process to provide high accuracy voltage detection while consuming relatively low amount of current. Each of the AAT8641 devices incorporates voltage comparators, bandgap reference voltage generator, signal delay circuit, short circuit detector, and digital control circuit. During the charge process, when the battery voltage is charged to a value higher than VC1 3μA Supply Current (Typical) 0.1μA Shutdown Current z 3-Level Over Current Detection: Over-Current Level 1 /Over Current Level 2 / Short Circuit z Wide Operating Temperature Range: − 40 z o C to +85 oC Small SOT25 Package PIN CONFIGURATION (Over Charge Threshold Voltage), the output of C out pin switches to low level, i.e., the VN pin level. The output of Cout pin will switch to high level when the battery voltage is at a level lower than VC 2 (Over Charge Release Voltage), or TOP VIEW COUT VN when the charger is disconnected from the battery pack and the battery voltage level is in between VC1 and VC 2 . During the discharge process, when the battery voltage drops to a value lower than VD1 (Over D OUT GND Discharge Threshold Voltage), the output of D out pin switches to low level immediately after the internal delay time elapses. The output of D out pin will switch to high level when the battery voltage is at a level higher than VD 2 – – 台灣類比科技股份有限公司 – Advanced Analog Technology, Inc. – Page 1 of 25 V2.0 Advanced Analog Technology, Inc. AAT8641 Series (Over-Discharge Release Voltage). Over Current Level 1 Voltage ( VOC1 ) is used to monitor the amount of discharge current. If the discharge current is high enough to cause VN pin voltage to be greater than VOC1 , the output of D out pin will switch to low level after a delay time tOC1. If the load is removed from battery pack, the output of D out will change to high exactly the same as discharge current. If the short circuit current is high enough to cause VN pin voltage to be greater than Vshort , the output of D out pin would fall to low level after a delay time t short , and the output of D out level will change to high when the load is removed from battery pack. again.
