TPS65982: Sink capability setting when there is no need to draw current

Part Number: TPS65982

Hi Team,

My customer’s product needs to support DRP(Toggling R_p/R_d) for Interoperability with Source/Sink peripherals. 

But the application fundamentally pretends as Source. And they don’t want it to be Sink except the case connecting with Provider only peripherals. So they assigns PP_HV as sink path and it left open since their application doesn’t need to pull current.

Then, they have a question about FW setting on Sink PDO.

Does Type-C standard including PD spec allow the following configuration (Supported DRP but no PDO supported as Sink)?

If it's allowable, What’s happened if TPS65982 doesn’t have Sink PDO as below?

If it’s NOT allowable, how much current shoud be set for  operating currents? 

Regards,

Takashi Onawa
