Hi Team,
Module : SC66A

In our present design, we are utilizing the USB_VBUS (PIN 41,42) to power our Vision device in a OTG (Vision device) configuration. We are using the USB1_HS_DM & USB1_HS_DP (in micro USB interface) line for communication between the two. (Page no. 52)

Here, the SC66 Hardware development document doesn’t mention anything about the current source capabilities of the USB_VBUS PIN.
We are operating our Vision device in this configuration:

So, when we use the USB_VBUS PIN in the above configuration, how much current can the USB_VBUS PIN drive?
We have few device failures, so this information is critical for us, for debugging.

Kindly revert for any clarifications.

Thanks for your support
