An apparatus and method is directed to a thermal wake-up circuit and a thermal sensor that are utilized by another circuit. The thermal wake-up circuit monitors a temperature associated with the other circuit. The thermal sensor is activated by the thermal wake-up circuit when the temperature exceeds a first threshold level. The thermal sensor is deactivated by the thermal wake-up circuit when the temperature is below the first threshold level. In one embodiment, addition thermal sensors may be activated and deactivated by the thermal wake-up circuit. The thermal sensor and additional thermal sensors may be used to activate protection circuitry or to shut down the other circuit. Power consumption by the thermal sensor is minimized by maintaining the thermal sensor inactive until activated by the thermal wake-up circuit.
