XHRA-2HPA USB_VBUS Pin for External Power Solutions

Postby DHembree » Fri Apr 15, 2016 7:06 pm

First post here. I am very new to this device. there does not seem to be a wealth of information in the data sheet regarding this, so I thought I would ask here. My system is to be powered from an external source - not USB powered. It is unclear what must be done with the USB_VBUS pin in this situation.

Thanks in advance,

Hi Dan,


Connect USB_VBUS to the VBUS pin of your USB connector; then the device can see when it is plugged in.

Have a look at the example application diagram in the data sheet.
