Description

The AIC1802 battery protection IC is designed to protect lithium-ion batteries from damage due to overcharging, overdischarging, and overcurrent for two series cells in portable phones and laptop computers. It can be a part of the low-cost charge control system within a two-cell lithium-ion battery pack.

Safe and full utilization charging is ensured by the accurate 30mV overcharge detection. Three different specification values for overcharge protection voltage are provided for various protection requirements. The very low standby current of AIC1802 drains little current from the cells while in storage.
