A heat control and temperature monitoring system (HCTMS) utilizes a thermal sensor to sense the junction temperature of a component, which becomes self-heated due to the quiescent leakage current inherent to the component upon the application of power to the component.

The method further includes reliably initializing the system by applying full system power and triggering a defined initialization sequence/procedure.
