Part Number: BQ76952

Hello Sir:

Please refer our attached file.

952 gg file.xlsx

That is our gg file, in our application, we don't use DSG and CHG driver outputs.

We only use DDSG and DCHG, we try to configure 0x2A or 0xAA on Settings:Configuration:DDSG/DCHG Pin Config

But which were no use, these two pins has no output voltage.

Please kindly teach us how to setup it.

Looking forward your feedback.

Thanks a lot.

Hi Statham,

I recommend reading this FAQ to see if there's any consideration that you may be missing: [FAQ] BQ76952: Do the DCHG and DDSG signals on the BQ769x2 follow the CHG and DSG FET driver pin states? - Power management forum - Power management - TI E2E support forums.

Also, it looks like the gg file was converted to an xlsx file, and looking at it DCHG and DDSG pin config are both 0x00, which doesn't seem right. Could you double check that this is the most up to date config file?

Regards,
