Abstract: A current detecting resistor is inserted in an H-bridge circuit constructed to cause the flow of a current to an inductive load in both forward and reverse directions by four semiconductor switching elements and flywheel diodes respectively connected in reverse parallel to the semiconductor switching elements. An inductive load driving method and an H-bridge circuit control device prevent an erroneous operation caused by noise generated at the current detecting resistor. When a current flowing through the inductive load is controlled by a detection voltage generated by the current detecting resistor, the value of the detection voltage is ignored immediately after the connection of the inductive load to a power source. There is no risk that an erroneous operation is caused by a rush current and/or a through current.
