ABSTRACT:
An apparatus for use with a semiconductor substrate includes a digital interface, a digital-to-analog converter and a thermal sensor circuit. The digital interface stores a value that indicates a desired thermal threshold, and the digital-to-analog converter provides an analog signal that indicates the value. The thermal sensor circuit uses the analog signal to set the desired thermal threshold and indicate when a temperature of the substrate exceeds the thermal threshold.
