The AP22654QWU-7 from Diodes Incorporated is a Single-Channel Precision Adjustable Current Limit Switch that is ideal for applications that require precision current limiting, or to provide up to 3.1 A of continuous load current under heavy loads/short-circuit events. It requires an input voltage of 3 - 5.5 V and delivers an output current of up to 3 A. This AEC-Q100-qualified switch offers a pin-strapped current-limit threshold from 0.4 A to 3.56 A via an external resistor and has its rise and fall times controlled to minimize current surges during turn on/off to achieve a maximum current limit accuracy. It offers a fast short-circuit response time for improved overall system robustness and provides a complete protection solution for applications subject to heavy capacitive loads. This RoHS-compliant switch limits the output current to a safe level when the output current exceeds the current-limit threshold. It is available in a surface-mount package that measures 2.8 x 2.6 x 0.7 mm and is suitable for automotive ECU supply rail power distribution and switching and automotive ECU supply rail precision current limiting applications.
