Abstract: A protection circuit for an electric appliance that is configured to control power supply to an associated electrical component of the appliance such as a heating device, lamp or motor in the event that unsafe conditions are detected. The protection circuit includes a first comparator module configured to compare an operating parameter input signal to a threshold value and to output a first control signal to a first switching circuit configured to control power flow to the associated electrical component.
