AP9101CAK-BPTRG1

Overview

The AP9101CAK-BPTRG1 is a single-chip protection IC developed by Diodes Incorporated for lithium-ion and lithium-polymer rechargeable battery packs. It integrates high-precision voltage detection circuits to monitor overcharge, overdischarge, overcharge current, and overdischarge conditions, automatically turning off external MOSFET switches during abnormalities. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.4 V to 4.5 V. It features low current consumption of 3 µA in operation mode and utilizes an SOT-25-5 surface-mount package.
