    usb3.0 controller, Surge, ESD,

      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 is 3.2V~6.0V of this chipset.


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