Abstract
In some examples, an integrated circuit (IC) is configured to detect, by the IC, a presence of liquid in an electrical connector. The IC is also configured to, responsive to the presence of liquid in the electrical connector, remove a bias voltage from at least some conductors of the electrical connector. The IC is also configured to monitor a bus voltage of the electrical connector. The IC is also configured to, based on a value of the bus voltage determined via the monitoring, perform a mitigation action responsive to the presence of liquid in the electrical connector.
Claims20
An integrated circuit (IC) configured to:
- detect, by the IC, a presence of liquid in an electrical connector;
- responsive to the presence of liquid in the electrical connector, remove a bias voltage from at least some conductors of the electrical connector;
- monitor a bus voltage of the electrical connector;
- and
- based on a value of the bus voltage determined via the monitoring, perform a mitigation action responsive to the presence of liquid in the electrical connector.
A method, comprising:
- introducing an electrical current into an electrical connector;
- measuring a voltage in the electrical connector provided responsive to the electrical current;
- determining, based on a value of the voltage, a presence of a foreign material in the electrical connector;
- and
- responsive to the presence of the foreign material in the electrical connector, removing a bias voltage from at least some conductors of the electrical connector.
An apparatus, comprising:
- a Universal Serial Bus (USB) receptacle;
- and
- a USB controller coupled to the USB receptacle, the USB controller configured to:
- detect a presence of liquid in the USB receptacle;
- and
- responsive to the presence of liquid in the USB receptacle, remove a bias voltage from at least some conductors of the USB receptacle.
