Applications
This IC is a high-precision constant-voltage/constant-current power control IC for lithium-ion battery charge
using a p-MOSFET as a power driver. It was developed for use with 1 to 3-cell chargers, and a constant
current value can be set freely with an external resistor. It has a built-in amplifier for detecting low battery
voltage. The lithium-ion battery charge function can be added to conventional chargers by using this IC.
