BQ24093: bq24093 NTC resistor K factor

Part Number: BQ24093
Other Parts Discussed in Thread: BQ24091

The bq24091/3 are designed to work with a 100k NTC. （100k NTC β = 3370）

I'd like to know what condition β = 3370 is under, it's not clear in the specs. Can you confirm that for me?

Hi Yunzhong,

β value commonly given over 25/50℃ or 25/85℃ . Is this what you are referring to?

I see ，but I'd like to know what temperature value β = 3370 refers to in the spec.
