3 Introduction
The TPS65994 is a stand-alone USB Type-C and Power Delivery (PD) controller providing cable plug and
orientation detection at the USB Type-C connector. Upon cable plug and orientation detection, the TPS65994
communicates on the CC line using the USB PD protocol. When cable detection and USB PD negotiation are
complete, the TPS65994 enables the appropriate power path and configures external multiplexers and alternate
mode settings. This user guide describes how the TPS65994 EVM can be used to test DisplayPort alternate
mode as well as USB Data. This guide also contains testing procedures of DP alternate mode as well as various
PD power configurations. The EVM is customizable through the TPS65994 Configuration Tool. Additionally, the
EVM is equipped with Tiva MCU and Aardvark connector to SPI or I2C interfaces for debugging and
development.
