2.3.3. Thermistor Interface (J104)

The thermistor input is used to detect an over temperature condition in a motor using a positive temperature
coefficient sensor. As the temperature of the sensor increases, so does the resistance. Under normal
operating conditions, the resistance of the thermistor is low (i.e., 100 ohms) which will result in a low input
signal. If the increasing temperature causes the thermistor's resistance to increase, the signal will be seen
as a logic high, triggering an over temperature fault.
