GENERAL DESCRIPTION
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 V
C1
(Over Charge Threshold Voltage), the output of
C
out
pin switches to low level, i.e., the VN pin
level. The output of C
out
pin will switch to high
level when the battery voltage is at a level lower
than V
C 2
(Over Charge Release Voltage), or
when the charger is disconnected from the battery
pack and the battery voltage level is in between
V
C1
and V
C 2
.
During the discharge process, when the battery
voltage drops to a value lower than
V
