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 RSS(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.
