Question:

How to use USB Type-C/PD Controllers of HX3C in USB PD compliant hub?

 

Answer:

HX3C is a USB PD compliant hub with two integrated USB PD controllers. This allows to design a hub with two USB PD compliant Type-C ports, one in Upstream and one in Downstream.

One of the USB PD controllers is used for providing USB PD capability to the upstream port of HX3C, whereas the second USB PD controller can be used to add USB PD capability to any one of the available downstream ports DS1, DS2 or DS4.
