TS3USB221E: Equivalent I/O Schematic Diagrams

K.Yaita

Part Number: TS3USB221E
Other Parts Discussed in Thread: TS5USBC402,

Hi Team,

Is there "Equivalent I/O Schematic Diagrams" for D+, D-, 1D+, 1D-, 2D+, 2D- pins?
My custromer wants to know where ESD protection diode is set for these pins.

Why not use TS5USBC402, it has better ESD performance and also has over voltage protection (OVP)?

Thanks
David

Hi David-san,

My customer has used TS3USB221E previously in his system and he wanted to know ESD discharge route.
So I asked the following.

Why do they need to know this info? This design is an old design and I can't find the exact schematic for this part, but the typical ESD structure on input will be like this.

Thanks

David

Hi David-san,

Thank you for your support.
I understand.

I think the information you provided is enough for my customer.
Let me post E2E again if we will need your further support.
