Abstract: An electronic device includes a first switch configured to connect a VCONN supply terminal of a Universal Serial Bus Type-C (USB-C) controller to a first configuration channel (CC) terminal of the USB-C controller in response to a USB-C connector being in a first orientation. A first current may flow through the first switch. The electronic device also includes an overcurrent component coupled to the first switch. The overcurrent component includes a second switch associated with the first switch. The second switch has a second current associated with the first current. The overcurrent component is configured to determine whether the first current is greater than a threshold current based on the first current and the second current. The overcurrent component is also configured to close the first switch in response to determining that the first current is greater than the threshold current.

Abstract: An electronic device includes a first electronic circuitry portion configured to connect a VCONN supply terminal of a Universal Serial Bus Type-C (USB-C) controller to a first configuration channel (CC) terminal of a plurality of CC terminals of the USB-C controller. The first CC terminal of the USB-C controller is to be directly connected to a first CC terminal of a plurality of CC terminals of a USB-C receptacle. The electronic device further includes a second electronic circuitry portion electrically coupled to the first electronic circuitry portion and configured to detect a voltage across the first CC terminal of the USB-C controller and the VCONN supply terminal. The second electronic circuitry portion is to decouple the VCONN supply terminal from the first CC terminal of the USB-C controller when the voltage is greater than a predetermined threshold.

Abstract: A device includes a USB-C controller instantiated as a first integrated circuit, the USB-C controller comprising a first pair of terminals to communicate with a first communication protocol that is other than USB, a second pair of terminals to communicate with a second communication protocol that is other than USB, and a third pair of terminals, each of which is to be coupled to a corresponding SBU1 terminal or SBU2 terminal of a type-C receptacle. The controller further includes a multiplexer to selectively couple the first pair of terminals to the third pair of terminals and the second pair of terminals to the third pair of terminals. The controller further includes a series of cascaded, low-voltage n-type field-effect transistors (LVNFETs) coupled between the multiplexer and each terminal of the third pair of terminals.

Abstract: An electronic device includes a power switch configured to receive a voltage on a first terminal. The first terminal is coupled to a voltage regulator. The power switch is also configured to provide the voltage to a second terminal. The second terminal is coupled to a VBUS terminal of a Universal Serial Bus Type-C (USB-C) connector. The electronic device also includes a protection circuit comprising a comparison component coupled to the first terminal and the second terminal. The comparison component is configured to detect a first voltage at the first terminal detect a second voltage at the second terminal. The protection circuit is configured to determine whether the second voltage is within a threshold voltage of the first voltage and adjust operation of the power switch in response to determining that the second voltage is within the threshold voltage of the first voltage.

Abstract: An electronic device includes a first switch configured to connect a first configuration channel (CC) terminal of a Universal Serial Bus Type-C (USB-C) controller to a VCONN supply of the USB-C controller. The first CC terminal of the USB-C controller being is to directly connect to the first CC terminal of a USB-C receptacle. The electronic device includes a second switch configured to connect a second CC terminal of the USB-C controller to a control channel physical layer logic (PHY) of the USB-C controller. The second CC terminal is to directly connect to the second CC terminal of the USB-C receptacle. The electronic device includes an overvoltage detection and protection circuit configured to deactivate the first switch or the second switch when a voltage exceeding a predetermined threshold is detected. The first switch and the second switch are each coupled to the overvoltage detection and protection circuit.
