AP9101CAK-BBTRG1

Overview

The AP9101CAK-BBTRG1 is a battery management IC 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 to turn off external MOSFET switches. The device features a high-precision voltage detection circuit with built-in fixed time circuits, eliminating the need for external capacitors. It operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.5 V to 4.475 V. The component is housed in an SOT-25-5 package and functions reliably across temperatures from -40°C to +85°C.
