AP9101CK6-ACTRG1

Battery Management Overview

The AP9101CK6-ACTRG1 is a single-cell lithium-ion or lithium polymer battery protection IC from Diodes Incorporated. It operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages between 2.5 V and 4.375 V. The device features ultra-low current consumption, drawing only 3 µA in operation mode at +25°C with a 3.5 V supply. It provides comprehensive protection against overcharge, overdischarge, overcharge current, and overdischarge current by controlling external MOSFET switches. The component is housed in an SOT-25-5 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.
