Abstract:
A circuit has a driver circuit with a slew-rate controller, an output stage and a monitoring circuit. The output stage is connected to a first bus line and to a second bus line, and the driver circuit is designed to control the output stage on the basis of a first logic signal in such a manner that a corresponding bus voltage is produced between the first bus line and the second bus line. The slew-rate controller is coupled to the driver circuit and is designed to set a slew rate of the driver circuit on the basis of an input signal. The monitoring circuit is designed to generate the input signal for the slew-rate controller, wherein the input signal indicates a higher slew rate during an arbitration phase of a data frame contained in the first logic signal than during a data transmission phase of the data frame.
