Description
The AP9211 is a 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-CHANNEL MOSFET with common drain.
The AP9211 provides rich battery protection features and can turn-off the N-CHANNEL MOSFET by detecting overcharge voltage/current, over discharge voltage/current, or load short circuit. AP9211 has builtin fixed delay time to save external components.
The AP9211 is available in U-DFN2030-6 package.
