AP9101CK6-AMTRG1

Battery Management Overview

The AP9101CK6-AMTRG1 is a high-efficiency synchronous step-down DC/DC converter manufactured by Diodes Incorporated. It integrates two N-channel power MOSFETs and a control circuit within a compact SOT-23-6 package. The device operates with an input voltage range of 2.5V to 5.5V, delivering a programmable output voltage from 0.8V to 3.6V. It supports continuous output currents up to 1A with a switching frequency fixed at 1.5MHz. Key electrical characteristics include low quiescent current for enhanced battery life and integrated protection features such as over-current, over-temperature, and soft-start functionality.
