as DRP, a vbus switch is needed to control Vbus . Pls check DRP or DFP design on datasheet.

We added a mosfet as switch for controlling VBUS. But still we are confused that by what signal the gate of mosfet will be controlled.

Designed schematics is attached. Please let me know

when in DFP mode, after CC detection completed, ID goes low and using ID to control mosfet.
