GENERAL DESCRIPTION
z
Ideal for One-Cell Rechargeable Li-Ion
Battery Packs
z
High Accuracy Voltage Detection
z
Low Current Consumption:
The AAT8660 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 AAT8660 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 VC1 (Over-Charge
Threshold Voltage), the output of C out pin

when the battery voltage falls lower than VC2
(Over-Charge Release Voltage), or when the
charger is disconnected from the battery pack and
the battery voltage level ranges 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 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).

AAT8660 Series
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 increase to a value greater than VOC1 , the
output of D out pin will switch to a low level
after a delay time t OC1 . If the load is removed
from battery pack, the output of D out will
identical to a discharge current. If the short
circuit current is high enough to cause VN pin
voltage increase to greater than Vshort , the output
of D out pin will move to the 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.
change to a high level again.
The mechanism of short circuit protection is
