Zusammenfassung:	An electronic control unit includes a booster circuit, a high-side switch, multiple low-side switches, a controller, a diode and a Zener diode. The booster circuit charges a booster capacitor to boost a power supply voltage supplied from a battery. The high-side switch drives an inductive load with a current through an output voltage of the booster circuit and the power supply voltage. The low-side switches are selectively turned on or off to control individual cylinders in an internal combustion engine. The controller controls the booster circuit, the high-side switch, and the low-side switches. The diode allows a current to flow back to the booster capacitor from a connection node between the inductive load and the low-side switches. The Zener diode is connected between the diode and the battery. The Zener diode clamps a voltage applied to the booster capacitor.
