STM32H735VGH as VBUS powered device

shaktipg · ‎2023-11-01

I'm configuring STM32H735VGH MCU for communicating by USB_OTG full speed, Device mode and want to power it by VBUS.

Suggest me best whether power distribution switch is required or not ?

Hello @shaktipg and welcome to the ST Community .

I suggest you take a look at this video that describe USB regulator (part 6 of the video) wish allow the USB to be powered directly from Vbus without any additional part. Also, the RM0468 can provide more details.

Best Regards.
