2.3.1 TPS25751D

The TPS25751D is a USB Type-C and Power Delivery (PD) controller providing cable plug and orientation detection for a single USB Type-C connector. Upon cable detection, the TPS25751D communicates on the CC wire using the USB PD protocol. When cable detection and USB PD negotiation are complete, the TPS25751D enables the appropriate power path for sourcing or sinking power depending on the contract negotiation and configuration.
