Since CCG4 is target for HOST, and HOST is not requirements for PPS source supply requirements on terminal products, for example Notebook.
May I know the applications on CCG4 for this requirements?
We use CCG4 for dock, based on the Cypress CCG4 dock ref design. As such, you need PPS both for the docking USB-C port (since Android phones now support desktop docking) and the secondary port which typically used to charge the mobile via the dock. Especially now with the new generation of mobile phone with very larg batteries (e.g. Samsung Ultra 5G) and PPS charging up to 45W customers wants this.
We use Southchip DC/DC converter with support for 20mV programmable voltage control, so supporting PPS from that point of view is simple.
Would it be possible to get a custom FW for CCG4 where you have enabled PPS (we are under NDA). Or are there any HW requirements for support PPS which is not available on CYPD4226.
CCG4 firmware SDK cannot support PPS currently. And the schedule of adding PPS support into CCG4 is not planned. If you are urgent for this, you could try to use CCG3PA on your end which is supporting PPS by default.
We are so sorry for any inconvenience.
