DIODES AP9214L-AA-HSBR-7

AP9214L is a single-chip protection solution specifically designed for single-cell lithium-ion rechargeable battery pack applications. AP9214L integrates a single-cell lithium-ion battery protection IC and dual N-channel MOSFETs with ultra-low on-resistance (R SS(ON)) in a common-drain configuration. AP9214L provides comprehensive battery protection functions, capable of turning off the N-channel MOSFETs by detecting overcharge voltage/current, overdischarge voltage/current, or load short circuit. AP9214L features built-in fixed delay times, eliminating the need for external components. AP9214L is available in a U-DFN2535-6 package with two pin configuration options.
