Abstract
According to an aspect, a switch circuit for a Universal Serial Bus (USB) connector device includes a main transistor configured to be activated during a normal operation of the switch circuit, a first voltage generator circuit configured to generate a voltage on a high local rail during an overvoltage event, a second voltage generator circuit configured to generate a voltage on a low local rail during the overvoltage event, where the low local rail is connected to a bulk of the main transistor, and a clamp circuit connected to the high local rail between the first voltage generator circuit and a gate of the main transistor, where the clamp circuit is configured to clamp the voltage between the high local rail and the gate of the main transistor during the overvoltage event.
