USB EZ-PD Type-C

Hi, I would like clarification on the use of the VDC_OUT pin on CYPD3177. I will be using this in a system where the main VBUS gate is not controlled by CYPD3177. So, VBUS_FET_EN and SAFE_POWER_EN will remain disconnected.

I would like to know the expected operation of CYPD3177 if VDC_OUT is left floating, grounded, tied to VBUS_IN, etc.

I would also like assurance that the D+/D- pins can be placed in parallel with a typical USB2 HS device, as this is not specified in the datasheet and the development board does not break out these pins.

Thank you
