The AP9211 is a single chip protection solution specially designed for 1-cell Li+ rechargeable battery pack application.
It includes a 1-cell Lithium ion battery protection chip and dual N-CH MOSFET with common drain. The chipset 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. Also with built-in fixed delay time to save external components.
