[FAQ] How to design for over temperature protection with a thermistor and a comparator

Is there a solution for over temperature protection using a comparator with external hysteresis? My automotive design requires the comparator output to toggle high when a temperature of 100C is reached. I would like the toggle low temperature to be 80C to act as some temperature recovery. I would like to use an open-drain/open-collector comparator.
