Description

The AP9234L family is a single chip protection solution specially designed for 1-cell Li+ rechargeable battery pack application.

The AP9234L includes a 1-cell high accuracy Lion battery protection chip and dual N-CH, ultra low RSS(ON) MOSFET with common drain.

The AP9234L provides rich battery protection features and can turn-off the N-CH MOSFET by detecting overcharge voltage/current, over discharge voltage/current, or load short circuit. AP9234L has built-in fixed delay time to save external components.

The AP9234L integrated highly accurate detection circuits and can compensate according to internal MOSFET Rsson performance to ensure extremely high charge/discharge current accuracy under both room and full temperature.

AP9234L is available in U-DFN2535-6 package.
