Abstract
An electronic heating module includes a heating transistor operated in its linear region as a current source. The temperature of the heating transistor is detected and used to control whether the heating transistor is turned on or off. Further control of the heating transistor is provided via a feedback control loop that monitors a voltage at one terminal of the heating transistor.
