Part Number: TPS25741
Other Parts Discussed in Thread: TPS65981, TPS65981EVM

We have used

TPS25741 for USB type-c power delivery and there is no data transmission through this port. 

What could be test cases that can be performed on USB type-C port in power point of view.

    Hello,

    Would you mind clarifying your question to me?

    Are you wanting to know how to set up the TPS25741 so that it can transmit data? Or are you just wanting to know how to set it up for Type-C PD?

    Hello,

    Do you currently own the TPS25741EVM? If not, I would suggest ordering that as it will give you the opportunity to work with the part and test different features from it. It can be found using the following link:

    http://www.ti.com/tool/tps25741evm-802

    Located in this link is also the user's guide for the EVM. This probably has the best walkthrough of how to use this part as well as shows an example of how to implement it within a schematic. The below figure is the functional block diagram for the TPS25741. This part has the ability for different power settings, which are determined based on the pin connections within the green box.

    Hi Adam,

    Thanks a lot for the info, its understandable and the EVM is just plug & play for testing this TPS25741. But my case is quite different, this TPS25741 & USB type-C are part of my system. My part is testing of this complete system, in that validation of USB type-C is part of that. As I already mentioned this tests are purely for PD there is no data transfer related testings. Finally we want to know the test cases that can be performed on this type-C. From TI portal I got the a user guide "SLVUAS7A–July 2016–Revised February 2017", few are covered in it. Would like to know the other test cases that can be performed.

    Rgds,

    Jagadeesh,

    I see. I would recommend using the TPS65981EVM to test the design and compatibility of the TPS25741 within your system. The TPS65981 has the capabilities of being either a sink, source, or dual role port allowing you to effectively test USB Type-C and Power Delivery end products. A link to purchase one as well as its user manual can be found below.

    Here's an example of how you will end up connecting your system to the EVM. Your system will be the host device acting as the DFP where as the TPS65981 will act as the UFP sinking power.

    I believe this answers your question. If so, you can close this thread by clicking This resolved my issue.
