TPS25751: Bin file for BQ25731

Hi Darren, 

Thank you for reaching out!

I will provide the binary files by the end of the week. 

Best Regards, 

Aya Khedr

Hi Aya, 

Thank you very much. I'll await the files. 

Hi Darren, 

No problem. I will follow up soon. 

Best Regards, 

Aya Khedr

Thanks. 

One last thing as I forgot it in the specs. I would need the BQ25731 to work at 400kHz and not at 800kHz. 

Thanks again. 

Hi Darren, 

The BQ25731 defaults to 400kHz so that should not be a problem. 

Best Regards,

Hi Darren, 

See full flash binary files attached. 

Please let me know if you have any questions/concerns.

Hi,

Thanks for the updated BIN files.

May we please get a modification of the provided BIN files for a TPS25751 coupled with a BQ25731 which will enable a "plugevent"  on GPIO11?

Thanks and Regards

Hi Darren, 

I will look into this and get back to you by tomorrow.

Hi, 

Sorry for late reply. We were on summer holidays. We'll test the BIN files and let you know. 

Thanks again

Hi,

We are currently testing these bin files and so far everything looks good except one particular issue. In OTG mode, a particular device (a 7inch monitor) is negotiating for 9V. During bootup, the device takes 9V 1.5A but after around 3sec, the device fails to boot and we see the current going down to a constant 0.3A. When we tested this device on other USB-C PD sources, we see that the device boots up correctly and takes 9V 1.5A steadily. As such, we are suspecting that the device has some current peaks during bootup which are driving our USB-C PD into some sort of protection. In this regards, what was the peak current percentage set for the source PDOs? Can these be set to 200% for the sake of testing?

Today is holiday in USA please allow some time to get back to you. 

Hi Darren, 

Do you have PD logs of the behavior observed with the monitor? 

Best Regards, 

Aya Khedr

Hi Aya, 

No. We where just shown a video of the issue happening on a prototype system we sent to a client, and we currently have no ways to get log. Is it possible to have the same bin files with the peak current percentage set to 200% for testing purposes?

On a second note, is there any planned date when the application customization tool for the TPS25751 will include the BQ25731?

Hi Aye,

Thanks. I will be able to check these files during this week and will get back to you.

Regards

Hi Aye, 

The files worked and the issue was resolved. Thanks.

I look forward for the updated GUI release.
