AP9214L (Not Recommended for new design)

Description

The AP9214L is a single chip protection solution specially designed for 1-cell Li+ rechargeable battery pack application.

The AP9214L includes a 1-cell Lion battery protection chip and dual N-Channel, ultra low R_SS(ON) MOSFET with common drain.

The AP9214L provides rich battery protection features and can turn-off the N-Channel MOSFET by detecting overcharge voltage/current, over discharge voltage/current, or load short circuit. AP9214L has built-in fixed delay time to save external components.
