AP9214L-AH-HSBR-7

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-CH, ultra low RSS(ON) MOSFET with common drain.

The AP9214L provides rich battery protection features and can turnoff the N-CH MOSFET by detecting overcharge voltage/current, over discharge voltage/current, or load short circuit. The AP9214L has built-in fixed delay time to save external components. The AP9214L is available in U-DFN2535-6 package with two kinds of pin options.
