    CY8C4125 ESD fail

    RoTs_4749531

      Hi,

      I am using 4125 with capsense feature in a desk lamp, when I do the ESD test, found something strange.

      My lamp is covered by plastic shell, so ESD is not easy to access into PCB borad, So I use the ground pin on the table to release ESD charge.

      It will shut down and reboot when I do this action, and will crash after several rounds.

      The behavior is very similar to excite the XRES pin, but I can also do this by using a metal rod to touch the GND pad on PCB, even some other exposed pads.

      Does anyone have the experince on this phenomenon?   

       

      Regards,

      Robert
