AP9101CK6-ASTRG1

Battery Management Overview

The AP9101CK6-ASTRG1 is a single-chip protection IC for 1-cell lithium-ion or lithium polymer batteries, manufactured by Diodes Incorporated. It detects overcharge voltage (3.5V to 4.5V), overdischarge voltage (2.0V to 3.4V), and associated current abnormalities to control external MOSFETs. The device operates within a supply voltage range of 1.5V to 5.5V and features low power consumption of 3.0µA in operation mode. It utilizes an SOT-26-6 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Battery Management Feature Summary
