Abstract
A temperature-based cooling device controller includes a register to store a threshold temperature value, a thermal sensor, and cooling activation logic to activate an active cooling device in response to an interrupt signal. The thermal sensor includes a current source, a voltage reference coupled to the current source to provide a bandgap reference voltage, wherein the bandgap reference voltage is substantially constant over a range of temperatures, programmable circuitry providing an output voltage that varies with the integrated circuit temperature and in accordance with the register value, and a comparator, wherein the comparator generates an interrupt signal if a difference between the output voltage and the bandgap reference voltage indicates that the threshold temperature has been exceeded.
