TPS65981: Internal ESD Structures

Part Number: TPS65981
Other Parts Discussed in Thread: STRIKE, PCM2705C

Hello,

What kind of internal ESD protection structures are built into the TPS65981ABTRTQT?

We have a board that will be protected inside a metal chassis and the USB cable connected to it will be fixed in place.

The current ESD protection devices are interfering with the board operation.  This has been confirmed because once we removed them the design works perfectly. 

We don't have time to redesign the board and using trace cuts/jumpers may not be an option

I am trying to gauge how much protection, if any, is built into the TPS65981ABTRTQT.

I appreciate any help you can provide.

Thanks,

Ben Schroeder
