AP9211SA-AK-HAC-7

AP9211SA-AK-HAC-7 is an AP9211 series single-chip protection solution specially designed for 1-cell Li+ rechargeable battery pack application. The AP9211 includes a 1-cell Lithium ion battery protection chip and dual N-CH MOSFET with common drain. The AP9211 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. The AP9211 has built-in fixed delay time to save external components. Typical applications include Li+ rechargeable battery pack.
