Abstract: Techniques for protecting universal serial bus (USB) Type-C dual-role power ports in computing systems are described. In an example, a first USB Type-C dual-role power port of a computing system is enabled to sink current from a high voltage external device to a power supply of the computing system. The current is transferred through a high voltage path from the first USB Type-C dual-role power port to the power supply. Simultaneously, a high voltage path from the power supply to a second USB Type-C dual-role power port of the computing system is disabled.

Abstract: The present disclosure relates to circuit protection within an information handling system and a media resource unit. In one form, an information handling system can include a first external input power port and an information handling system docking interface operable to be coupled to a media resource unit interface of a media resource unit. The media resource unit can include a second external input power port. The information handling system can also include a protection circuit including a first terminal and a second terminal. The first terminal can be coupled to the first external power port and operable to receive input power from the second external power port of the media resource unit. The second terminal can be coupled to the information handling system docking interface and operable to output protected power to the media resource unit interface.
