3 Description
The TPS65987D is a stand-alone 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 TPS65987D communicates on the CC wire using the USB PD protocol. When cable detection and USB PD negotiation are complete, the TPS65987D enables the appropriate power path and configures alternate mode settings for external multiplexers.
