GENERAL DESCRIPTION
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
1
C
V (Over-Charge
Threshold Voltage), the output of
out
C
pin
switches to the low level, i.e., the
VN
pin level.
The output of
out
C
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
C1
and
V
C2
.
During the discharge process, when the battery
voltage drops to a value lower than
1
D
V
(Over-Discharge Threshold Voltage), the output
of
out
D
pin switches to low level immediately
after the internal delay time elapses. The output
of
out
D
pin will switch to high level when the
battery voltage is at a level higher than
2
D
V
(Over-Discharge Release Voltage).

AAT8660 Series
Over current level 1 voltage (
1
OC
V
) 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
1
OC
V
, the
output of
out
D
pin will switch to a low level
after a delay time
1
OC
t
. If the load is removed
from battery pack, the output of
out
D
will
change to a high level again.
The mechanism of short circuit protection is
identical to a discharge current. If the short circuit
current is high enough to cause VN pin voltage
increase to greater than
short
V
, the output of
out
D
pin will move to the low level after a delay
time
short
t
, and the output of
out
D
level will
change to high when the load is removed from
battery pack.
