GENERAL DESCRIPTION
The AAT8635 series are protection ICs designed
to safeguard one-cell rechargeable Li-Ion battery
pack against over charge, over discharge, over
current, and short circuit. The AAT8635 series
use advanced high voltage CMOS process to
provide high accuracy voltage detection and low
current consumption.
The AAT8635 series incorporate a reference unit
and three voltage detectors. During the charging
process, when the cell voltage (
DD
V
) is charged to
a value higher than the over charge threshold
voltage (
V ), the over charge detector (COM1)
will switch the output pin (
within a delay time (
1
), and thus turning off the
MOSFET connected to the charging path. The
C
pin may change to high level again when
the
DD
V
voltage falls below “
when
DD

falls below
V while the charger is
disconnected from the battery pack.
