ONE-CELL LI-ION BATTERY PROTECTION IC
FEATURES
Ideal for One-Cell Rechargeable Li-Ion
Battery Packs
High Accuracy Voltage Detection
Low Current Consumption:
GENERAL DESCRIPTION
The AAT8661 series are designed to protect
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 and low current
consumption.
Each of the AAT8661 devices incorporates
voltage comparators, bandgap reference voltage
generator, signal delay circuit, short circuit
detector, and digital control circuit.
In the charge process, when the battery voltage is
charged to a value greater than V
C1
(Over-Charge
Threshold Voltage), the output of C
out
pin
switches to the low level, i.e., the
VN
pin level.
The output of C
out
pin will switch to high level

when the battery voltage falls lower than V
C2
(Over-Charge Release Voltage), or when the
charger is disconnected from the battery pack and
the battery voltage level ranges between V

.
During the discharge process, when the battery
voltage drops to a value lower than
V
D1
(Over-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
V
D 2
(Over-Discharge Release Voltage).
