BQ40Z50-R2: thermistor

Hi

I use BQ40Z50_R2

Which model is suitable for thermistors?

I'm using 3950K now. If I change it to 3435K, does that make any difference?Do we need to recalibrate, do we need to recalibrate, do we need to loop through this?Are the two parameters compatible?

thanks

    Hi, David

        The NTC used on bq40z50EVM is 103AT-2

       If you use this NTC, you do not need to modify NTC parameters if you use this type of NTC. otherwise you need to optimize the NTC parameters before you do calibration.

       Calibration Temperature is needed what ever NTC you will be using to get better temperature accuracy. This can be done with built in tools in bqStudio. Affected parameters are modified by gauge automatically after calibration is done.
