Hello,
Would you be able to give more information on the Type-C port this device is being used in? Specifically why they are wanting to implement a protection device like the TPD6S300 if there is no CC controller?
We just want to use it on a regular type C for the computer without ThunderBolt. From the Intel guideline, the CC1/CC2 connect to the Thunderbolt PD, but we are not using Thunderbolt so no PD is needed. so right now, we only have C_CC1 and C-CC2 connect to the CC1 and CC2 of the USB C.
Hello Binh,
There are other times when a PD controller is needed, not just for Thunderbolt. For example, if you want to support >5V, you will need a USB Type-C PD controller. If you want to support alternate modes like DisplayPort, you will need a USB Type-C PD controller.
If you could share the entire Type-C requirements that would be helpful
Hi Adam.
we only support 5V for USB C. We want to have USB 3.0 speed on USB-C and running DisplayPort in the USB Type-C port too.
is there a reason why we need the PD controller if we running DisplayPort?
Thanks
The DisplayPort negotiation that takes place on a Type-C port occurs between the two PD controllers. So if you would like to support DisplayPort on your Type-C port, you must implement a PD controller. There is really no way around this requirement since the DisplayPort negotiation happens on the CC pins which connect to a Type-C PD controller.
Device that we would recommend to allow for this negotiation is the TPS65987D
This make sense. Just want to confirm, The C_CC1 and C_CC2 of the TDP6S300 will go to the CC1/CC2 of the USB Type C connector. The CC1/CC2 of TDP6S300 will go to the Type-C PD.
Do you recommend other product beside TPS65987D. The problem with TPS65987D is the operating temperature.
We need to operate minimum of -40C-+70C
Would the TPS65994ADRL work?
Thank you

Yes that is exactly right
For the device recommendation, if you require the lower temp range, then the TPS65994AD would be the correct device to use.
