Abstract: A system of monitoring and protecting integrated circuits against damage due to over temperature conditions functions to monitor the temperature of an IC and either shut down its input clock signal or assert its reset line if case temperatures rise to high. Heat dissipated by an integrated circuit is sensed by a temperature sensor. The temperature sensor is thermally coupled to the integrated circuit via thermal glue or other thermally conductive means. The output of temperature sensor is input to temperature sensor circuitry which converts the low level output of the temperature sensor into a signal that can be read by a processor. The processor is suitable programmed to monitor the output of temperature sensor circuitry. When the temperature of the integrated circuit rises past a predetermined threshold value, the processor outputs a control signal to the clock generator circuitry causing it to switch off its clock signal input by the integrated circuit or asserts the chips reset line.
