Hi,

But I found R_S is -759ohm, is it mean BQ24075 can't support this temperture? Thanks!

Hello Jeff,

With your chosen NTC, there are no resistor values that can achieve a 0°C to 45°C temperature range.

I recommend checking out the BQ24075T, which uses a voltage-based TS function and will allow you to achieve this range. The calculator for it is included in the same spreadsheet you're using.

Best regards,

Alec
