The TPS2022D: The N-channel MOSFET delivers a typical on-resistance of 33 mOhm, keeping conduction losses low in USB hubs, industrial sensors, and general-purpose power distribution. A status flag output signals the fault condition to the host controller.
No external Vcc supply is required — the switch is self-powered from the load rail.
