[FAQ] When do I select a PD controller or CC controller for USB Type-C applications?

Implementing USB Type-C can help to increase the USB ports functionally and create a more friendly experience for the end user. To implement USB Type-C one of two devices is generally always required, either a PD controller or CC controller. PD (Power Delivery) controllers allow all features of USB Type-C to be implemented. PD controllers can be used in all applications using USB Type-C and can come with a power switch integrated into the package. CC controllers allow for the main features of USB Type-C to be implemented but leave out features that require PD messages over the USB Type-C connector. CC controllers are generally used in application that require a small solution size, low power consumption and simple bring up. The table below shows a list of commonly used USB Type-C features and whether a PD controller or CC controller can be used to implement them.
