Diodes Incorporated AP9211S-AD-HAC-7

Description
The AP9211 is a single-chip protection solution designed for 1-cell Li rechargeable battery pack applications. It includes a 1-cell Lithium ion battery protection chip and dual N-CH MOSFET with common drain. The AP9211 provides battery protection features and can turn off the N-CH MOSFET by detecting overcharge voltage/current, overdischarge voltage/current, or load short circuit. It has built-in fixed delay time to save external components.
