Title: Load driving circuit
Inventor: MAEDA AKIRA
IPC: G05F1/56
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To prevent unwanted radiation of switching noise or electromagnetic waves from being generated by providing a constant current outflow circuit for the outflow of prescribed current from the control terminal of the switching element when turning a load to inactive state. SOLUTION: As the switching element, an FET 1 is serially connected to an inductive load M1 and connects/disconnects a current to flow to the load M1. When a changeover switch SW is changed over to off for turning the load M1 into inactive state, the current flows out of a gate G of FET 1, the voltage of gate G decreases, the FET 1 is turned to a non-conductive state and the current of the load M1 is cut off so that the inactive state is provided. In this case, the constant current flows out of the gate G of FET 1 through a constant current circuit S1. Thus, the generation of spike voltage caused by the sudden change of the load current Id at the time of load operation stop peculiar for the inductive load is suppressed and the unwanted radiation of switching noise or electromagnetic waves is suppressed.

Abstract: PURPOSE:To cancel both an H and an L pulse as noises by providing an AND gate, an OR gate, and an RS flip-flop for making only accurate data effective. CONSTITUTION:When an input signal is thin H pulses, the thin H pulses inputted from an input signal line 15 and thin H pulses which are delayed by a delay circuit 16 are inputted to an AND gate 18 and canceled by the AND gate 18, so that no thin H pulse is outputted to an output signal line 20. When the input signal is thin L pulses, thin L pulses inputted from the input signal line 15 and thin L pulses which are delayed by the delay circuit 16 are inputted to the NOR gate 19 and canceled by the NOR gate 19, so no thin L pulse is outputted to an output signal line 21. Then the set/reset flip-flop 22 gathers the output signals of the AND gate 18 and NOR gate 19. Consequently, the thin H and L pulses are both canceled as noises.
