I came up with an idea using USB Power Delivery / Quick charge. I did some research in the topic, but please excuse me if my terminology is not correct.
The device I would like to make is a fairly simple charge controller for phones/notebooks. It only has 2 type-c connectors, one for the power source and one for the phone/notebook which has to be charged. The phone/notebook is running some software which is communicating with the charge controller over USB, using this the user is able to limit the charge speed or set battery limit (e.g: stop at 80%).
During my research I found your company product EZ-PD™ CCG3PA which seems a perfect fit to this problem. I watched the video series and read some specifications/articles on the topic, but I'm still not sure if this idea is feasible.
As an expert what do you think is this idea feasible?
Are there any similar products which I'm unaware of?
Are there any common pitfalls which I should be aware of?

I have a total of 16 PWBs build of which two I am unable to program the CYUSB4357-BZXC. I checked all the supply voltages, chip selects , and so forth and everything seems okay. On one PWB, I've replace the flash and USB HUB twice and still can't program the USB HUB. Additionally the PWB was X-ray'd in that area and nothing out of the ordinary was observed. Via X-ray both the USB connector and transient protection devices seem soldered down properly. I'm not sure what to do next. What specific signals, voltages does the USB HUB need for programming? I included my design implementation and screen capture of the programming errors. What signals should I be concerned with? I did notice D+/D- levels appear to be transitioning logic low/logic high versus looking at a those signals on a working device where the levels are much faster and smaller (differential voltages).

Our firmware is monitoring a fault gpio line from a load switch that is asserted when a connected device is faulting and pulling too much current. If fault condition does not clear within certain time I call app_disable_pd_port() to disable further activity on the port.
After a delay and when the fault flag has cleared I want to enable the port again. What is the correct way to do this? There is no symmetric API call to enable the port.
