負荷の電流検出回路。An inductive load, a switching element, and a first resistor are connected in series, and a series circuit consisting of a second resistor and a diode is connected in parallel to the inductive load. The switching element is directionally coupled so that the voltages are applied in the same direction, and the voltages of the first, second and second resistors are level-converted and summed so that they are continuous during conduction and cut-off of the switching element. Current detection circuit for inductive loads.
