Beschreibung
Zusammenfassung:	An electronic circuit for switching and controlling a current flowing through a plurality of loads so that it is proportional to a reference signal irrespective of an unbalance and a varaition of the hFE values of current amplifying transistors wherein a current detector detects the total current flowing through the loads and the output of said detector is used as a feedback signal. When the circuit is used to control an electronically commutated motor, a motor generating a smooth and constant torque is easily obtained.
