AP22652/3 Current Limited Switches

Diodes' AP22652 and AP22653 are single-channel, precision adjustable, current-limited switches optimized for applications requiring precision-current limiting. A key feature of the devices is their programmable current-limit threshold, between 125 mA and 2,665 mA, set using an external resistor. Current-limit accuracy ±10% can be achieved at high current-limit settings. This flexibility allows for a wide array of applications. The AP22652 and AP22653 offer a robust solution as they offer controlled turn-on and turn-off, overcurrent protection, sudden short-circuit protection, reverse-current protection, and a flag that signals the system if the overcurrent event is longer than 6 ms. Internal overtemperature protection ensures a robust system design that recovers from an overcurrent event. The AP22652 has an active-low enable, whereas the AP22653 has an active-high enable. All devices are available in SOT26 and W-DFN2020-6 packages.
