Abstract
Aspects of the invention include a semiconductor device that includes a voltage-controlled type semiconductor element connected to a primary side of an ignition coil for supplying a voltage to an ignition device of an internal combustion engine, a first resistor and a second resistor inserted in series in a supplying path of an input signal for controlling a gate of the voltage-controlled type semiconductor element and a current control circuit including a current limiting circuit for controlling current flowing through the voltage-controlled type semiconductor element. Aspects of the invention also include a first by-pass forming element that is connected in parallel to the second resistor and by-passes the second resistor in a turning ON process of the voltage-controlled type semiconductor element, and a second by-pass forming element that is connected in parallel to the first resistor and the second resistor.
