Hi team,
I'm considering the USB-C interface circuit as DRP using TUSB321AI.
This circuit is configured to support DRP (Dual-Role Power) mode.
However, we want the circuit to be powered solely by the host's VBUS when the TUSB321 functions as a device.
Therefore, as shown in the attached block diagram, we believe that the VDD of the TUSB321 should be supplied from two sources—VBUS and another onboard power supply—using two ideal diode or back-to-back FETs.
In this case, what is the recommended way to connect the VDD pin of this IC to the power supply?
