2 Multi Port Source Policy Management

The Source Policy Manager is a feature of the TPS65988 (dual port) PD controller that allows the system to restrict power sourced when both the port controllers inside the TPS65988 device are in the Source role. This feature is enabled by setting MultiPortSourcePolicy to 1 (Bit #7 of byte 13 of the Global System Configuration Register (0x27)). This feature is also dependent on two other bits:

  • TBTControllerType [Bits 5:4 of Global System Configuration Register (0x27)]

  • Prevent High Current Contract Event (GPIO Input configuration (port specific))
