Hi,
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.
NOTE
USB_OTG_VBUS and USB_H1_VBUS are not part of the power supply
sequence and can be powered at any time.
4.3.2.3 LDO_USB
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?
Solved! Go to Solution.
Dear Igor igorpadykov
Just in case,
Is it acceptable to keep same situation(all powers off except USB 5V) over 72 hours?
Thanks
Hi torus1000
yes acceptable.
Best regards
