AAT AAT8640

The AAT8640 series are designed to protect one-cell rechargeable Li-Ion battery pack against High Accuracy Voltage Detection over-charge, over-discharge, over-current and Low Current Consumption: short circuit. They use CMOS process to provide 3μA Supply Current (Typical) high accuracy voltage detection and low current consumption. The output of C out pin will switch to high level PIN CONFIGURATION TOP VIEW VN VDD COUT 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.
