We have lineup of charge control IC that are suitable for charging 1-cell Li-ion battery and Li polymer battery.
This IC features stable charging by high accurate voltage/current control.
High safety is achieved by abnormal protection by battery temperature detection using external thermistor, and charging timer.
In addition, it is possible to support a wide range of charging voltage and charging current, so can be built a charging system compatible with various battery.
