ONE-CELL LI-ION BATTERY PROTECTION IC
FEATURES
Ideal for One-Cell Rechargeable Li-Ion Battery Packs High Accuracy Voltage Detection Low Current Consumption:
3A Supply Current (Typical) 0.1A Shutdown Current
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 VC1 (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 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
C out
(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 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 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.
