Hi Biser,
The question is different from e2e.ti.com/.../2835778 which I posted.

I would like to confirm whether AM3517 could work with 4.4V VBUS power or not.
Am I making sense?

Best regards,
Hitoshi

Hello,

No, this is not recommended. Please keep in mind that although VBUS_VALID is 4.4V, the USB specification requires VBUS =>4.75V (depending on topology).
