I want to confirm about VBUS pin as following.
According to the i.MX6S/DL datasheet, USB_H1_VBUS input pin seems separated from other power domains.
USB_OTG_VBUS and USB_H1_VBUS are not part of the power supply
sequence and can be powered at any time.
The LDO_USB module implements a programmable linear-regulator function from the
USB_OTG_VBUS and USB_H1_VBUS voltages (4.4 V–5.25 V) to produce a nominal 3.0 V output voltage.
Is it OK to leave USB_H1_VBUS supplying 5V for a while even all other power supply were off?
Can anyone help?
