Abstract
A system includes a first USB Type-C Power Delivery (USB-C/PD) port and a control circuit operatively coupled to the first USB-C/PD port. The control circuit is configured to determine whether a short circuit condition has occurred based on a first threshold voltage. The control circuit is also configured to turn off a ground isolation switch when short circuit condition occurs. The control circuit is further configured to determine a whether a voltage on a ground line is less than a second threshold voltage. The control circuit is further configured to turn on the ground isolation switch when the voltage on the ground line is less than the second threshold voltage. The control circuit may perform one or more error recovery operations after turning on the ground isolation switch.
