    How to protect  D+/D- data line in self-powered design

    takafumi.ono

      I am working at small device maker.

         

      Where we are using the CY68013 to product .

         

      Two devices that were shipped recently has been returned in failure.

         

      I have received reports that D+/D- line is a short circuit. (shorted internally, not by board solder)

         

       

         

      What is the cause of a short circuit?

         

      Would there a way to protect on the circuit?

         

       

         

      for past few years, problems did not occurred.
