ONE-CELL LI-ION BATTERY PROTECTION IC  
FEATURES  
GENERAL DESCRIPTION  
z Ideal for One-Cell Rechargeable Li-Ion  
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.  
Battery Packs  
z High Accuracy Voltage Detection  
z Low Current Consumption:  
3μA Supply Current (Typical)  
0.1μA Shutdown Current  
z 3-Level Over Current Detection:  
Over-Current Level 1 /Over Current Level 2  
/ Short Circuit  
Each of the AAT8641 devices incorporates  
voltage comparators, bandgap reference voltage  
generator, signal delay circuit, short circuit  
detector, and digital control circuit.  
z Wide Operating Temperature Range:  
o
40 C to +85 oC  
z Small SOT25 Package  
During the charge process, when the battery  
voltage is charged to a value higher than VC1  
(Over Charge Threshold Voltage), the output of  
Cout 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 VC2 (Over Charge Release Voltage), or

when the charger is disconnected from the battery  
pack and the battery voltage level is in between  
VC1 and VC2 .

During the discharge process, when the battery  
voltage drops to a value lower than VD1 (Over  
Discharge Threshold Voltage), the output of  
Dout pin switches to low level immediately after
