    usb3.0 controller, Surge, ESD,

    content.librarian

      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) ?

         

       

         

      Please refer to attached picture.

         

      Thanks.
