Abstract

The present invention relates to a circuit arrangement for controlling the current in loads by modulation of the pulse width, comprising at least two driver stages (10) provided for the actuation of the loads, and one or more current measuring devices (3), and at least one multiplexer (4) conducting current measurement signals by way of the load current in the driver stages to one or more current measuring devices in dependence on one or more control signals (30, 31) for the multiplexer, said control signals being produced by a checking device (5). The invention further describes a method wherein the moment of the current measurements is controlled by an organized chronological order.
