Abstract:
An inductive load driving circuit comprising:a main transistor for supplying a current path to an inductive load, an auxiliary transistor that is connected in parallel with the main transistor, and a control circuit, having a first driver that supplies a first control signal to the control terminal of the main transistor, a first wave shaping circuit that slows the rise and fall of the first control signal, a second driver that supplies a second control signal to the auxiliary transistor, and a second wave shaping circuit that slows the rise and fall of the second control signal, and which turns on/off both the main transistor and auxiliary transistor, wherein the first wave shaping circuit has a first capacitor connected to the control terminal of the main transistor, and the second wave shaping circuit has a second capacitor connected to the control terminal of the auxiliary transistor.
