For the formulas defined in the spec sheet, am I correct in using Vcold = 0.705 and Vhot = 0.479?
Hi mfraguglia,
Thank you for contacting the MPS Forum. The NTC equations actually depend on the NTC resistor you choose. The datasheet does a great job of explaining the formula calculation, I recommend reading the Resistor Selection for the NTC Sensor on page 30. Essentially, choose the temperature limits you are comfortable with and you will be able to get the resistance of the NTC at said temperatures. After that, you can calculate for the voltage f the Cold and Hot limits.
Thanks,
