Abstract:
An electronic circuit, comprising:a switch element for controlling power supplied to a load, the switch element including a metal-oxide-semiconductor field effect transistor (MOSFET);wherein the MOSFET is of enhancement type and includes a drain electrode, a gate electrode and a source electrode, with the source electrode being coupled to a ground level; and,wherein the load is to be coupled between a power source and the drain electrode of the MOSFET; and,an activation element, coupled to said switch element, for activating said switch element to control power supplied to the load, said activation element including a sensor for sensing whether there is a change in condition and for delaying activation by said activation element of said switch element upon sensing a change in condition, said activation element further including a capacitor and a switch;wherein the capacitor is coupled between the power source and the switch of said activation element;wherein the switch of said activation element is coupled between the capacitor and the gate electrode of the MOSFET; and,wherein said sensor is coupled between the gate electrode of said switch element and the ground level.
