Describes

This IC is high-side protection IC for lithium-ion / lithium polymer rechargeable batteries, which includes high-accuracy voltage detection circuit, delay circuit, and triple boost charge pump to drive an external charge / discharge FET. It is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent.

By using an external overcurrent detection resistor, this IC realizes high-accuracy overcurrent protection with less effect from temperature change. 

Applications

● Lithium-ion rechargeable battery pack

● Lithium polymer rechargeable battery pack
