9.2.2.2 Liquid Detection
The TPS25751 supports liquid detection using the built-in internal ADC and GPIO with external circuitry. Figure
9-8 and Figure 9-9 show the hardware implementation for liquid detection with the TPS25751. The TPD2S300
is used to protect the GPIO, ADC, and LDO_3V3 pins from over voltage conditions when there is liquid shorting
VBUS to the SBU1/2 pins. Table 9-3 shows the recommended components used to implement the external liquid
detection circuitry. When liquid is detected, the TPS25751 takes action to protect the Type-C port. Systems using
an embedded host controller, can leverage the Host Interface for additional notification and control.
