Diodes Incorporated announced the introduction of the AP22913, a 2.0A single-channel, slew-rate-controlled load switch with true reverse current blocking (TRCB) 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 large output capacitors (100µF) associated with the USB port and self-powered USB peripherals create the possibility that the load switch may become reverse-biased, which creates the potential of reverse current flowing from the load to the source, potentially causing damage to other components or active cables. The AP22913A load switch incorporates TRCB, which removes the normal body diode unwanted current paths to provide a cost-effective and space-efficient solution to load switching (more info).
