[Outline]
This IC is a one-cell lithium ion battery charge control IC for AC chargers.
The charging current and charging voltage can be optimally controlled by controlling the primary side through a photocoupler.
It incorporates a charging over timer, delay circuit for misoperation prevention, and overvoltage/overcurrent detection functions.
It includes a 2-channel LED display circuit, which allows displaying the charge status.
