7.4.4 Dead Battery Operation

For most automotive applications, PD dead battery operation is not required. Short the RPD_G1 and RPD_G2 pins to ground so that the dead battery resistors are not provided to the connector CC1 and CC2 pins.

For this application, dead battery support is required, so short RPD_G1 to CC1 and short RPD_G2 to CC2. Shorting the pins is done to ensure the dead battery resistors are present, even when no system power is provided.

For more information on the TPD4S480-Q1 dead battery operation, see the CC Dead Battery Resistors Integrated for Handling the Dead Battery Use Case in Mobile Devices section of the data sheet.
