Description
The AP9234L family is a single-chip protection solution specially designed for 1-cell Li+ rechargeable battery pack application.
The AP9234L includes a 1-cell high accuracy Li+ battery protection chip and dual N-CH, ultra low RSS(ON) MOSFET with common drain.
The AP9234L provides rich battery protection features and can turnoff the N-Channel MOSFET by detecting overcharge voltage/current, overdischarge voltage/current, or load short circuit. AP9234 has builtin fixed delay time to save external components.
