3.6 USB Type-C Connector: DFP and UFP

The DFP and UFP USB Type-C® connectors share a similar design. Both use a TVS2200 to help protect against transient voltage events, ESD diodes, and capacitors to bias the SS signals. From a evaluation perspective, the DFP port should be used to evaluate the TPS25814 as a port controller, and the UFP port should be used when evaluating the data capabilities of the EVM.
