AP9101CK-AXTRG1

Battery Management Overview

The AP9101CK-AXTRG1 is a battery management IC from Diodes Incorporated, designed for single-cell lithium-ion and lithium-polymer rechargeable batteries. It provides comprehensive protection by detecting overcharge voltage, overdischarge voltage, overcharge current, and overdischarge current, subsequently turning off an external MOSFET switch to safeguard the battery. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.8 V to 4.4 V. It features low current consumption, with typical operation mode current of 3.0 µA at +25°C and power-down mode current of 0.01 µA. The component is housed in a SOT-25-5 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.
