Abstract:
In an example embodiment, a method for a Universal Serial Bus Type-C (USB-C) controller is provided. The method comprises: coupling a control channel PHY of the USB-C controller to a first configuration channel (CC) terminal of the USB-C controller; coupling a VCONN supply terminal to a second CC terminal of the USB-C controller; detecting that a voltage across the second CC terminal of the USB-C controller and the VCONN supply terminal is greater than a predetermined threshold; and in response to detecting that the voltage is greater than the predetermined threshold, decoupling the VCONN supply terminal from the second CC terminal of the USB-C controller.
