Simultaneous usb and vin power - openmv cam h7 plus

Dear all,
I am designing an application where the cam will be powered by an external dc/dc converter with 5v output and I plan to connect it to the vin pin.

When updating firmware I will need to connect to the board with a usb cable.

This may bring the 5v usb and onboard regulator output together.

Is there any protection on the openmvcam h7 plus to prevent damages in this situation?
Same situation with other camera modules?

Thanks,
Lorenzo

The H7 Plus has protection for this. It will choose the VIN input over the USB and things will work fine.

USB into VIN can never happen.

VIN disabled USB input and the mosfet will not let current go backwards when off.

Thankyou so much for the answer!
…. And for the schematic.
