Abstract: Described are mechanisms and methods to facilitate power saving in Type-C connectors. Some embodiments may comprise an interface to a Configuration Channel (CC) signal path and to a ground signal path of a Universal Serial Bus (USB) Type-C connector port, a first circuitry, and a second circuitry. The first circuitry may be operable to place toggled values on the CC signal path. The second circuitry may be operable to couple the ground signal path to a detection signal path. The placement of the toggled values on the CC signal path is enabled when the detection signal path carries a first value that corresponds with the USB Type-C connector port being connected to a USB Type-C device, and may be disabled when the detection signal path carries a second value that corresponds with the USB Type-C connector port not being connected to a USB Type-C device.
