### Thermistor Temperature Sensor

The thermistor is a temperature sensitive resistor. The output of the thermistor is buffered to create feedback voltage on Pin 1 of the power connector. Refer to Table 3 and equation below for thermistor temperature vs. Pin 1 feedback voltage.

Thermistor:

Betatherm 0.3K1CG2

R = Thermistor

Resistance Ω

A = 0.0018590668

B = 0.0002367000

C = 0.0000007811

R is the resistance of the thermistor. The resistance of the thermistor can be calculated from the voltage on pin 1 using the following equation.
