Diodes Incorporated AP22653Q Precision-Adjustable Current-Limited Power Switches are optimized for applications that require precision current limiting or to provide up to 1.5A of continuous load current during heavy loads/short circuits. The AP22653Q Switches provide a programmable current-limit threshold between 125mA and 1735mA (typ) via an external resistor. Utilizing high current limit settings, a ±7% current limit accuracy is achieved. Rise and fall times are controlled to minimize current surges during turn on/off.

The AP22653Q provides a complete protection solution for applications subject to heavy capacitive loads and the prospect of short circuit, offering reverse current blocking and limiting, overcurrent, overtemperature, short-circuit protection, as well as controlled rise-time and under-voltage lockout functionality.

A 6ms de-glitch capability on the open-drain flag output prevents false overcurrent reporting and does not require any external components. The AP22653Q limits the output current to a safe level when the output current exceeds the current-limit threshold.

The Diodes Inc AP22653Q Precision-Adjustable Power Switches have a fast short-circuit response time for improved overall system robustness and are available in the SOT26 (Type A1) package.
