CCG2 USB Type-C Power Bank Solution

[BrFo_2046856]

The CCG2 USB Type-C Power Bank Solution page listed below indicates the design is able to act as a DRP (dual role port).    It calls out  CYPD2134-24LQXIT as one of the 2 major components on the board.

Looking at the CCG2 datasheet, the CYPPD2134 appears its meant for a DFP Role.    

Based on the CCG2 datasheet, I would infer that the Power Bank solution would require a CYPD2122 where the role is specified as DRP.   Am I missing something which would enable the CYPD2134 to function as a DRP in this design?

Hi,

Your understanding is correct. CYPD2134 can only function as DFP.  If you want to build a DRP design, then you can only choose CYPD2122.
