8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The TUSB320 device is a Type-C configuration channel logic and port controller. The TUSB320 device can

detect when a Type-C device is attached, what type of device is attached, the orientation of the cable, and power

capabilities (both detection and broadcast). The TUSB320 device can be used in a source application (DFP), in a

sink application (UFP), or a combination source/sink application (DRP).

8.2 Typical Application

Figure 10 and Figure 11 show a Type-C configuration for the DRP mode.
