BQ20Z60R1 NTC temperature coefficient meaning

Team,

What does the "Ext temp coef 1..4" plus "min AD" plus "max temp" correspond to as found p 212/213 of sluu386? I guess 1 to 4 correspond to polynomial coef but how about "min AD" and "max temp"?

Do we have something similar to this suitable for BQ20Z60?


thanks

    Hi Olivier,

    All of these parameters have to do with modeling the external thermistor (note: internal thermistor constants should not be altered).  

    I have attached a a link to SLUA398, which includes an app note and a spreadsheet for calculating these constants.

    Best,

    Justin
