    摘要: Disclosed is an electromagnetic valve driving circuit capable of reducing a load of a booster circuit. A boost driving FET 202 is connected to a route formed between the booster circuit 100 and a first terminal of an injector 3. A battery-side driving FET 212 and a battery protection diode Db are connected to a route formed between a positive-polarity side of a power supply and the first terminal of the injector 3. A freewheeling diode Df is connected at a first terminal thereof to a portion between the first terminal of the injector 3 and the battery protection diode Db, and at a second terminal thereof to a grounding side of the power supply. An injector downstream-side driving FET 220 is connected to a route formed between the second terminal of the injector 3 and the grounding side of the power supply. In addition to operating the FETs 202, 212, and 220 according to a level of a current which flows through the injector 3, a control circuit 240 activates the battery-side driving FET 212 during a period in which the boost driving FET 202 repeatedly turns on and off a plurality of times.
