4.3.3 Liquid Detection and Corrosion Mitigation Overview

TPS25751AEVM supports liquid detection and corrosion mitigation to protect the system from unexpected shorts (liquid, moisture, and debris) on the USB Type-C port. In the Liquid Detection state, TPS25751A monitors the SBU, CC, or DP/DM lines for unexpected shorts to ground or high voltage (5V and above). The configuration of the pins used for liquid detection is chosen by the user. TPS25751A supports corrosion mitigation by automatically disabling the Type-C port when a short is detected. When a short is no longer detected across the monitor pins, TPS25751A enters back into normal operation. For GUI application configuration details, see USB-C PD Application Customization Tool User's Guide.
