TPS25750: Application Customization tool generating wrong file

Hi Darren,

If you are currently in development, you should not be using the TPS25750 for new designs. The successor part, the TPS25751 was recently released to market and it is a pin to pin replacement with the intent of solving the issues found with the TPS25750.

Is there planned any solution to solve this bug?

The planned solution is the TPS25751.

Most of the support has been moved to the new device, and support for the TPS25750 is limited. If possible, we strongly encourage switching to the TPS25751.

I spoke to Alex and he provided some feedback.

Did you try the binary file he shared for the TPS25750EVM? It should be configured for the 731.

TPS25750_EVM_Source_Sink.bin

What is your intended use case for the TPS25750?

Power roles?

• Source/Sink?
• What power levels

Data?

Can you share the json you are using? I can take a look to see if there are any issues from the .json.

Thanks and Regards,

Chris

HI, Chris,

Thank you for the quick reply. I tired to find sourcing for the TPS25751 to get samples but I cannot find the device on top distributors (mouser, digi-key, tme etc..). Would it be possible to get some samples directly from TI for prototyping? 

Thanks for this binary. I had tried it already and it works in source. But I don't know its exact configuration. Can I get this info pls?.

My intended use case if for both source and sink with the below options on the Application customization tool

Both source and sink (EVM choice) 

60W source, 60W sink

Preferred power role as source

No USB Data, No vendor ID, No product ID

BQ25731 charger

Charging voltage = 16.752V, current = 3.072A

The json file is the following

{"questionnaire":{"version":"7.0.4.7","answers":[0,3,3,0,0,null,1,null,1,null,2,16.752,3.072,null,null],"options":{},"configID":"0000","vendorID":"0000"}}

Thanks

The device is in the process of releasing and samples should be available on the web soon. If you reach out to your local TI sales team, they should be able to help you 

I'll see if I can get the original json file and share an updated binary. Please give me a couple days to get back to you.

Thanks and Regards,

Hi Chris, 

Thanks. I'll wait for your reply. 

Hi Chris, I order the TPS25751 and received them today. After I soldered one of the samples, I opened the Customization Application tool and realized that the BQ25731 is not supported. 

So right now, I am in a position where I either need a fix for the TPS25750, or need the TPS25751 application to support the BQ25731 or else I would need to re-design using the BQ25713. On the other hand, I noticed that the BQ25731 and BQ25713 has practically the same register map. Can I select the BQ25713 in the application tool and download the data to be used on the BQ25731 for testing?

Hi Chris, 

The bin file you sent me worked! Thanks. 

is there a way I could manage to modify the bin file myself if need different settings?

Hi Darren,

Unfortunately, there is no way for you to modify the bin file yourself.

If you have specific questionnaire settings, I can try to update the bin for you.

Otherwise, you may have to wait for the next GUI update that should include the BQ25731.

Thanks and Regards,

Chris
