BQ24030: BQ24030 temperature monitoring

Eugene Kozhukhov

Part Number: BQ24030

Can I use 100k NTC thermistor (in datasheet is 10k) with bq24030 charger? Or can I leave TS pin floating in case I don't need battery temperature monitoring?

Hi,
Since the TS pin has a constant current source and set voltage thresholds, you can only use a 10k NTC thermistor. You can just place a normal 10K resistor on this pin if you don't intend to use it.

Hi Raheem,

Thanks for your quick reply! Yes, I already found this simple solution in EVM board schematic.
