摘要
In a current controlling apparatus for controlling a load current flowing through a load, a reference level generating circuit generates a reference level signal, and a reference signal generating circuit generates a reference signal in accordance with the reference level signal. A bridge circuit includes a plurality of semiconductor elements so that the semiconductor elements are turned ON and OFF to supply the load current to the load. A sensing circuit senses the load current, to thereby generate a sense signal in accordance with the load current. A current correction circuit including a correction comparator compares the sense signal with the reference level signal to generate a correction signal, so that the reference signal is corrected by the correction signal.
