The TC622 and TC624 are programmable solid state temperature switches designed to replace mechanical switches in sensing and control applications. Both devices integrate the temperature sensor along with a voltage reference and all required detector circuitry to form a stand-alone temperature switch. The desired temperature set point is set by the user with a single external resistor.
