TIME SENSOR CIRCUIT

WIPO Patent Application WO/2010/038309

A1

A time sensor element (1) and a voltage-dividing resistor (R1) are connected in series with a power source (E1), and an FET (Q1) has its gate connected with the junction of the time sensor element and the voltage-dividing resistor. Moreover, the gate of an FET (Q2) is connected with the drain of the FET (Q1) and further with the power source (E1) through a resistor (R2). Still moreover, the source of the FET (Q2) is connected with the power source (E1), and a load (11) is connected with the drain of the FET (Q2). According to this constitution, in case the resistance in the time sensor element (1) varies with time up to a predetermined value, the FET (Q1) is turned OFF, and the FET (Q2) is also accordingly turned OFF. As a result, the power supply to the load (11) from the power source (E1) is cut off.
