Is it possible to run this device off a (nominal ) 5V DC supply and turn off the Type-PD functionality of this device leaving only the Type-C functionality (at 3A) and the legacy functionality (e.g. USB BC 1.2 etc).
Or possibly restricting the PD advertising to 15W (5V 3A) whilst providing the Type-C and Legacy charging capability as stated above?
Many Thanks
Neil

Thanks, Fred

Hi Neil,
I think it's doable, the CCG3PA has the ability to support PD3.1 PPS and 2*legacy/proprietary charging blocks (Supports QC 4.0, Apple charging 2.4A, AFC, BC 1.2), integrates all required terminations on DP/DM lines, supports one USB Type-C port and one Type-A port.
For your application, you need a dedicated firmware support.
I'm not sure whether you can achieve your goal by configuring the existing firmware, I will confirm it.
By the way, could you kindly provide us which CCG3PA IC you selected?
Regards,
Neo
