AP9101CK6-BATRG1

Battery Management Overview

The AP9101CK6-BATRG1 is a single-cell battery management IC from Diodes Incorporated, designed for lithium-ion and lithium-polymer rechargeable batteries. It provides protection by detecting overcharge voltage, overdischarge voltage, overcharge current, and overdischarge current to turn off external MOSFET switches. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages between 2.3 V and 4.28 V. It features low power consumption with a typical operating current of 3 µA at +25°C and 3.5 V. The component is housed in an SOT-26-6 package and functions reliably across a temperature range of -40°C to +85°C.
