  • Architectures for detecting USB type-C device exposure to liquids
    Patent number: 12045111
    Abstract: A system includes a USB-C receptacle including first and second non-GPIO pins and a USB-C controller including a first GPIO pin connected to a pull-up resistor and a second GPIO pin connected to a pull-down resistor, a pair of non-GPIO pins including a third non-GPIO pin corresponding to the first non-GPIO pin and a fourth non-GPIO pin corresponding to the second non-GPIO pin. The pair of GPIO pins is selectively connectable to the pair of non-GPIO pins using a multiplexer, and liquid exposure detection circuitry configured to cause a first voltage for the first GPIO and a second voltage for the second GPIO to be measured, determine whether the first and second voltages each satisfy a threshold condition, and in response to determining that the first and second voltages each do not satisfy the threshold condition, cause operation of the USB-C receptacle to be suspended.
