Hi support,

I have a project using CY7C65631 as a HUB USB 4 ports. Currently, I am using PWR# pins to enable external USB power switch. I already checked on the CY7C65631 datasheet but I do not know the PWR# pin status when the HUB USB power off.

Could you please help us on this case?

Thanks,

Ty

Hello Ty,

- The default state of the PWR# pin of the CY6C65631 is floating (Z). This is mentioned in the datasheet in table 3.

- When the hub is powered OFF, the PWR# pin remains floating and will not be driving LOW on the output line.

Best regards,

Srinath S
