4.4 Liquid Detection and Corrosion Mitigation Overview

TPS25751EVM 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, TPS25751 monitors the SBU lines for unexpected shorts to ground or high voltage (5V and above). TPS25751 supports Corrosion Mitigation by automatically disabling the Type-C port when a short is detected. When a short is no longer detected across the SBU pins, TPS25751 enters back into normal operation. See the hardware implementation in Figure 4-11, for hardware requirements and see also the TPS25751 USB Type-C® and USB PD Controller with Integrated Power Switches Optimized for Power Applications data sheet.

Note: Liquid Detection and Corrosion Mitigation and BC1.2 cannot be configured in the same system. Both applications utilize GPIO4 and GPIO5 of TPS25751 for different functions.
