TUSB320: IDpin's configuration.

Part Number: TUSB320
Other Parts Discussed in Thread: TPS66020,

Hi team.

I'd like to configure TUSB320 and TPS66020.

I have a question about the IDpin's configuration for TUSB320.

Is the ID pin asserted Low when the DFP or the DRP is connected?
I care if it works well When TPS66020 connecting IDpin to EN.
EN1's configuration is bellow.
*EN0 is fixed high.

High : Source pass
Low : Sink pass

Sincerely.
Kengo.

ID pin asserted low for DFP or act as DFP of DRP when an UFP is attached .

Hi Kengo,

TUSB320's ID pin is active low. ID is asserted when UFP is connected to the port and CC negotiation is completed. TUSB320 must be in DFP or DRP acting as source mode for ID to be valid. In this case ID pin will cause TPS66020 to enter SNK state when it should be in SCR 3.0A.
