Diodes Incorporated has announced the introduction of the AP22913, a 2A single-channel, slew-rate-controlled load switch with true reverse current blocking for high-side load-switching applications.
Single-channel high-side load switches provide an effective way of applying or removing power to a load, particularly to removable peripherals powered through a USB port.
The AP22913A load switch incorporates true reverse current blocking, which removes the normal body diode unwanted current paths to provide a solution to load switching.
With a load current of up to 2A across a wide operating voltage range, the AP22913 is designed to deliver a typical Rds(on) of 92mΩ at 1.5V and 54mΩ at 5.0V. The firm claims this achieves maximum load current handling capacity with a low forward voltage drop.
The turn-on slew rate of the device is controlled internally to provide a soft-start feature for sensitive loads while the device also features an active-high enable input to enable load switching. To ensure true reverse current blocking when disabled and in its off state, the vin and vout terminals are completely isolated internally.
