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.
Yes, it can get damaged.
What do you mean by not working? Is it powering up? Is the board getting recognized by the PC?
