Abstract
In an interface between a high-active driving circuit for driving a predetermined semiconductor power element and a microcomputer for controlling an output signal of the driving circuit, the microcomputer comprises a transistor, a collector terminal of which is an output side of the microcomputer; and the driving circuit comprises a first resistor, one end of which is directly connected with the output side of the microcomputer; a Schmidt circuit which is connected in series with the other end of the first resistor; a diode, an anode side of which is connected to a path between the first resistor and the Schmidt circuit; a power supply voltage connected with a cathode side of the diode; and a second resistor, one end of which is grounded and the other end of which is connected with a side of the first resistor being an input terminal of the driving circuit.
