Abstract:
Certain aspects of the present disclosure generally relate to methods and apparatus for providing overvoltage protection for circuitry coupled to connector ports, such as USB-C ports. One example circuit for overvoltage protection between a connector port and a signal node corresponding to the connector port generally includes a first switch having a first terminal for coupling to the connector port and having a second terminal for coupling to the signal node; a first resistive element coupled in parallel with the first switch; a first transient protection circuit coupled between the signal node and a reference potential node; and a control circuit having an input coupled to the signal node and having a first output coupled to a control input of the first switch.
