<p>An inductive load driving device and a method for driving the same device in which the rise of load current at an initial stage of driving can be executed at high speed. To this end, the device comprises a plurality of step-up circuits (21, 31) for alternately applying a high voltage to the same inductive load within a predetermined period of time to thereby allow a load current to rise at high speed respectively, a holding current output circuit (43) for applying a predetermined voltage to the same inductive load after the load current has risen to thereby hold the load current at a predetermined value, a plurality of switching means (46, 47) adapted to be switched in such a manner that the respective outputs of the plurality of step-up circuits (21, 31) and the holding current output circuit (43) can alternatively connected to the same inductive load, and a control logic circuit (44) for switching the plurality of switching means (46, 47) in a predetermined sequence.</p> |
