Abstract
A method and a control unit for driving a control circuit (1) are suggested which make possible an improved distribution of the generated power loss. A component (15), especially of a motor vehicle, is driven via at least two outputs (5, 10) of the control circuit (1). Each output (5, 10) is connected pairwise to one of several potentials (40, 45) via controllable switch means (20, 25; 30, 35) and a drive voltage (UA) is formed for the component (15) from a difference between the potentials at the two outputs (5, 10). A pregiven clocked course of the drive voltage (UA) is adjusted by switching more than one of the controllable switch devices (20, 25; 30, 35).
