を特徴とするリニアソレノイド駆動回路。 A control pulse generation circuit generates an overexcitation signal and a duty signal at different timings in response to a control signal, and the overexcitation signal and duty signal from this control pulse generation circuit are input, and the overexcitation signal is current amplified. At the same time, it is driven by a current drive output circuit that amplifies the current by making the peak value of the duty signal smaller than the peak value of the overexcitation signal, and a stepped signal consisting of the overexcitation current and duty current from this current drive output circuit. In the linear solenoid drive circuit, the current drive output circuit includes a first transistor to which the overexcitation signal is supplied, a second transistor to which the duty signal is supplied, and a linear solenoid drive circuit comprising a first transistor and a solenoid. a transistor that is supplied with a signal from the second transistor and outputs a current sufficient to drive the solenoid; and a control transistor that is supplied with a signal from the second transistor and whose output is controlled so that the output does not exceed a predetermined current. A linear solenoid drive circuit characterized by comprising:
