Abstract
A temperature monitoring circuit and control system for compensating for self-heating effects of a thermistor used for measuring a temperature within a system includes a thermistor, a pull-up resistor, a node configured to receive a reference voltage, and a node configured to supply a sensed voltage; the control system measures a voltage across the thermistor; determines a thermistor resistance based on a known supply voltage and a known biasing impedance supplying current to the thermistor; determines thermistor temperature based on the thermistor resistance; determines a thermal rise value due to thermistor self-heating based on the known supply voltage, the thermistor's heat dissipation constant, and the calculated thermistor resistance; and creates a compensated thermistor temperature value by subtracting the thermal rise value from the determined thermistor temperature thus providing a more accurate measurement of the device being monitored by the thermistor.
