PROBLEM TO BE SOLVED: To provide solenoid valve drive device having improved power efficiency with a simple structure.SOLUTION: A solenoid valve drive device includes: a switching element that has a high-pressure side main terminal, a low-pressure side main terminal and a control terminal, and is connected to a coil in series between one end and the other end of a direct current power source; and a control unit that has a power source terminal, a reference terminal and a signal output terminal, and performs on-off drive to the switching element. The power source terminal is connected to the high-pressure side main terminal, the reference terminal is connected to the low-pressure side main terminal, and the signal output terminal is connected to the control terminal.SELECTED DRAWING: Figure 1 |
