ABSTRACT:
In an IC having a power dissipating element, an integral thermocouple is located so as to respond to the thermal gradient in the IC chip that results from such power dissipation. Control circuitry, also on chip, responds to the thermocouple output and acts to limit dissipation to produce a predetermined maximum thermal gradient.
