BQ24171: About RTHCOLD,RTHHOT

okashita.ikki

Part Number: BQ24171

Tool/software:

I want to adjust the error of the temperature sensor.
I want to perform RT1 and RT2 calculations, but what are the values of RTHCOLD and RTHHOT in the following equation?

I searched the specifications but couldn't find it.

Hi Okashita, the RTHHOT and RTHCOLD should be find in your thermistor datasheet at the temperature you would like to set as the HOT and COLD threshold.

Hi Jing

Is it sufficient to substitute the temperature range in which the temperature sensor can be used (e.g., -50°C to 125°C)?
Or is it the resistance value?

Best regards,
Okashita

Hi Okashita,

It will need to be the resistance value from the Thermistor datasheet.
