Description

The AIC1803 is designed to protect the lithiumion battery from damage or degrading the lifetime due to overcharging, overdischarging and overcurrent for three-cell lithium-ion battery powered systems such as notebook PCs. It can also provide the cell-balancing "bleeding" function to automatically discharge the overcharged cell until the overcharge condition is released.

Safe and full utilization charging is ensured by the accurate ±30mV overcharge detection. Four different specification values for overcharge protection voltage are provided for various protection requirements. The very low standby current of AIC1803ACS drains little current from the cell while in storage.
