AP22653 Overview
The AP22652, AP22653, AP22652A, and AP22653A are singlechannel, precision-adjustable, current-limited switches optimized for applications that require precision current limiting, or to provide up to 2.1A of continuous load current during heavy loads/short circuits. These devices offer a programmable current-limit threshold between 125mA and 2665mA (typ) via an external resistor. Current-limit accuracy ±10% can be...
