AIC1802 Two-Cell Lithium-Ion Battery Protection IC n FEATURES l n 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 twocell 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 drains little current from the cells while in storage. Ultra-Low Quiescent Current at 10 µA (V CC =7V, VC =3.5V). Ultra-Low Power-Down Current at 0.2µA (V CC =3.8V, VC =1.
