Dear Team,

Our customers also have the following problems:

How long does it take for the CC PIN of TPS25810 to detect changes to nPOL and nUFP have output?

Another question is what is the define of deglitch as below?

Thanks a lot!

Hello Jimmy,

The values you showed in the above screenshot answer this question. For asserting deglitch time, what this value is saying is that it will take approximately 150ms for UFP, POL, AUDIO, DEBUG to be asserted once an event has been presented. And vice versa for the de-asserting.

Hope this helps answer your question

Hi team,

We appreciated your great support!

May I ask why the CC PIN has not been activated, but the IC already knows that something is inserted as below?

Is it related to the DRP operation principle of the IC?

Many Thanks!

Jimmy
