AP9101CAK-AUTRG1

Overview

The AP9101CAK-AUTRG1 is a single-chip protection IC designed for lithium-ion and lithium-polymer battery packs. It integrates high-precision voltage detection circuits to monitor overcharge, overdischarge, overcharge current, and overdischarge current conditions. The device controls external MOSFET switches to isolate the battery during fault events. It features a built-in fixed time circuit that eliminates the need for external capacitors, reducing component count. The IC operates within a supply voltage range of 1.5 V to 5.5 V and supports detection voltages from 2.4 V to 4.5 V with typical quiescent current of 3 µA in operation.
