摘要
In an example embodiment, a Universal Serial Bus Type-C (USB-C) cable comprises a respective integrated circuit (IC) controller, disposed at each end of cable, that is coupled to a respective VCONN line at that end of the cable. Each IC controller comprises a power rail, a VDDD terminal, a VBUS terminal, and a VCONN terminal that is coupled to the VCONN line at the respective end of the cable. The VDDD terminal, the VCONN terminal, and the VBUS terminal are coupled to the power rail. The power rail is coupled to internal circuits of the IC controller and is configured to provide operating power to the internal circuits of the IC controller from the its VCONN terminal.
