The AIC1804 is designed to protect the lithiumion battery from damage or degrading the lifetime due to overcharging, overdischarging and overcurrent for three- or four-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.
