Diodes Incorporated AP9214LA-AG-HSB-7

Description
The AP9214L is a single-chip protection solution designed for 1-cell Li rechargeable battery pack applications. It includes a 1-cell Li-ion battery protection chip and dual N-CH, ultra-low Rss(ON) MOSFETs with a common drain. The AP9214L provides comprehensive battery protection features and can turn off the N-CH MOSFETs by detecting overcharge voltage/current, overdischarge voltage/current, or load short circuit. It has built-in fixed detection delay time to eliminate the need for external components. The AP9214L is available in a U-DFN2535-6 package with two pin options.
