Voltage protection for universal serial bus Type-C (USB-C) connector systems

A system, comprising:

• a Universal Serial Bus Type-C (USB-C) connector;
• a first switch configured to connect a first configuration channel (CC) terminal of a Universal Serial Bus Type-C (USB-C) controller to a first CC terminal of the USB-C receptacle;
• a second switch configured to connect a second CC terminal of the USB-C controller to a second CC terminal of the USB-C receptacle;
• and
• a voltage protection circuit configured to deactivate one or more of the first switch and the second switch when a voltage exceeding a predetermined threshold is detected, wherein the voltage protection circuit comprises;
• a first set of rectifying elements coupled to the first CC terminal of the USB-C receptacle;
• and
• a second set of rectifying elements coupled to the second CC terminal of the USB-C receptacle.

A method, comprising:

• receiving a first voltage via a first switch coupled to a first configuration channel (CC) terminal of a Universal Serial Bus Type-C (USB-C) controller and a first CC terminal of a USB-C receptacle;
• receiving a second voltage via second switch coupled to a second CC terminal of the USB-C controller and a second CC terminal of the USB-C receptacle;
• detecting that the first voltage or the second voltage exceeds a threshold voltage;
• and
• turning off, in response to the first or second voltages exceeding the threshold voltage, the first switch and the second switch.
