TUSB1044: design the active cable which PD should choose

Hi,

You should look into TPS25750 but the best solution will depend on your exact power tree requirements. I recommend posting a new thread with PD controller PN to get the best recommendation.  

Hello  Malik

Thank you for your answer, but there still have some questions.

1. The device TPS25750 doesn’t support Alternate mode.
2. From my understand the active cable there is one plug and one receptacle,

both of them should add the PD device?

3. If the HUB insert the active cable how the PC’s PD get the PD message form the HUB?

Hello Malik 

Do your have any suggestion?

Hi,

Active cables should have USB-C plugs on both sides. The application you are referring to us more like a dock or adapter application

PD accounts for messaging to active cables through the use of E-markers for true active cable application e-markers should be used to communicate what data/video the cable supports.
