USB Superspeed Peripherals

Anonymous
Not applicable

I used the usb3.0 controller (CYUSB301X) for USB camera.

   

A few days ago, cameras did not working.

   

I supply 5V power for usb_vbus using 5V SMPS then I found power off surge. ( max : 7~8V , 10~20 nano second )

   

 

   

I wonder this power off surge can give a damage to CYUSB301X ?

   

The operating condition of this chipset is 3.2V~6.0V .

   

But can give a damage to the chipset through the very short time (10~20 nano seconds , not micro second) ?

   

 

   

Please refer to attached picture.

   

Thanks.
