Description

The AP9221 is a single-chip protection solution specially designed for 1-cell Li+ rechargeable battery pack applications.

The AP9221 includes a 1-cell Lithium ion battery protection chip and dual N-CH MOSFET with common drain.

The AP9221 provides rich battery protection features and can turn-off the N-CH MOSFET by detecting overcharge voltage/current, overdischarge voltage/current, or load short circuit. The AP9221 has built-in fixed delay time to save external components.

The AP9221 is available in the U-DFN2030-6 (Type C) package.
