Current control and protection for universal serial bus type-C (USB-C) connector systems

A system, comprising:

• a Universal Serial Bus Type-C (USB-C) connector;
• and
• a power switch configured to:
• receive a voltage on a first terminal, wherein the first terminal is coupled to a voltage regulator;
• provide the voltage to a second terminal, wherein the second terminal is coupled to a VBUS terminal of the Universal Serial Bus Type-C (USB-C) connector;
• and
• a protection circuit comprising a comparison component coupled to the first terminal and the second terminal, wherein:
• the comparison component is configured to:
• detect a first voltage at the first terminal;
• and
• detect a second voltage at the second terminal;
• and
• 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.

A method, comprising:

• detecting a first voltage at the first terminal;
• detecting a second voltage at the second terminal;
• determining whether the second voltage is within a threshold voltage of the first voltage;
• and
• adjusting operation of the power switch in response to determining that the second voltage is within the threshold voltage of the first voltage.
