ABSTRACT:
A temperature monitoring circuit comprises a thermistor which is connected with a power supply rail by means of a transistor. The transistor is pulsed to connect the thermistor intermittently in circuit with the power supply. The mean power drawn by the thermistor from the power supply is reduced, causing less drain on the power supply.
