TPS25810 / Source VCONN Discharge

Other Parts Discussed in Thread: TPS25810

Hi Team,

There is USB Type-C ECN(Engineering Change Notice) for "Source VCONN Discharge" in usb.org.
The content is "Add a new state, UnattachedWait.SRC, to the Source Connection State Diagram".

Does TPS25810 support it?
My customer wants to know it.

I downloaded USB3.1 specification from following link and see USB Type-C ECN for Source VCONN Discharge.pdf in usb_31_080416\USB Type-C\USB Type-C ECNs.

Hi Yaita-san,

I did receive an answer but it is no since TPS25810 was released/designed before the ECO.

Hi Eric-san,

Thank you for your support.
I understood TPS25810 doesn't support ECN for "Source VCONN Discharge".

Is there any plan to support it?
For example, any workaround with TPS25810 or design new device etc.

Best Regards,
Yaita
