The TPS65994AE is a stand-alone USB Type-C and Power Delivery (PD) controller providing cable plug and orientation detection for two USB Type-C connectors. Upon cable attachment, the TPS65994AE performs cable detection according to the USB Type-C specification. It also communicates on the CC wire using the USB PD protocol. When cable detection and USB PD negotiation are complete, the TPS65994AE enables the appropriate power path and configures alternate mode settings for external multiplexers.
