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

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

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

(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.

The mechanism of short circuit protection is
