Abstract
A conductive liquid path detection circuit for detecting a conductive liquid present in a receptacle connector and/or a mating connector plug is configured for discharging an electron charge from any conductive liquid present on a connector pin in the receptacle connector and/or a mating connector plug. The conductive liquid path detection circuit charges any conductive liquid present on the connector pin with an electron charge. The circuit repeatedly samples and retains the samples of the measurements of a voltage level present at the connector pin. The conductive liquid path detection circuit then analyzes the samples of the measurements to determine a slope of the samples of the measurements of a voltage level over time; and determines when an amplitude of a final measurement of the voltage level is less than a conductive liquid detection threshold level.
