May unused USB OTG pins be connected to ground?

frankambrosius — Fri, 03 Apr 2015 09:56:48 GMT

As clearly stated in the HDG, the unused USB OTG pins should be left floating when unused.

However, I need them (OSB_OTG_DN and DP) to be connected to ground. Is this allowed? What are the consequences of doing this?

Thank for all the help!

Regards,

Frank

Hi Frank

yes they can be connected to ground, with consequences

of small leakage.

Hi Igor,

Thank you for your reply.

Can you also indicate how much the leakage current will be?

Is this specified in the datasheet?

Hi Frank

I am afraid this was not measured, however

it is small current.
