BQ76972: NTC Temperature Coefficient Calculator

Tool/software:

Hello,

I just submitted a zip file to the BQ769x2 Thermistor Coeff Calculator to use the GPC tool.

However, I am aware of this post https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/998410/bq76952-temperature-accuracy-without-calibration

I was curious of the the GPC tool gives the best results for coefficients now, or if there is an internal tool I should be aware of. I've attached the CSV file of the NTC data I will be using in this design.

    Hi Alec, 

    The Thermistor Coeff Calculator GPC tool, is the previously "internal more accurate way of calculating the thermistor", that was now released to the public. That post is from 4 years ago, where we used to have an excel tool instead of the Coeff calculator SW. This GPC release is the most accurate way to calculate your coefficients. 

    Regards,
