8.2.2.2 Liquid Detection

The TPS26750 supports liquid detection using the built-in internal ADC and GPIO with external circuitry. Figure 8-7 and Figure 8-8 show the hardware implementation for liquid detection with the TPS26750. The TPD4S480 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 8-3 shows the recommended components used to implement the external liquid detection circuitry. When liquid is detected, the TPS26750 takes action to protect the Type-C port. Systems using an embedded host controller can leverage the Host Interface for additional notification and control.
