Other Parts Discussed in Thread: TUSB320LAI, TPS2069D, ESD122, TPS25810, TPD1E05U06, TVS2200, TPD6S300A,
Hello,
My customer is designing Type-C USB application (Only DFP, USB2.0, no PD) with TUSB320LAI, AM335x and TPS2069D.
Then they are asking what ESD devices are the best for this configuration.
I found some similar posts in E2E, but I’m not still clear.
Because it doesn’t use PD, VBUS is 5V. So they don’t need to think about 20V VBUS short to CC pins ideally.
So if they don’t worry about the VBUS short, just putting usual ESD component like TPD4E5U06 or ESD122 on CCx/DP/DM is enough.
But if they want to think of any irregular cases, putting TPDS6S300A on CCx/DP/DM or TPDS2S300 on CCx and ESD112 on DP/DM would be good solution.The above is my understanding. What do you think?
And how to think about VBUS pin? Is it common to put any ESD or TVS on DFP VBUS line?
