Hello Cory,
Sincere apologies for the delay in response, I was checking internally with the concerned team for the feasibility of your application. Please find the responses below:
-The HX3PD PD controller can support only 2 ports and act as a source. So, you would have to add external PD controller for the other two ports and modify the firmware accordingly.
-Please note that HX3PD PD ports are designed for PD Source role and not designed for DRP role so the device could only be sinking power.
-The PD contract related information from HX3PD PD controller can be sent through the DMC as it acts as I2C master for the PD controller on the I2C_1 interface.
Best Regards,
Sananya
