Abstract: A method for driving an electromagnetic load, particularly a solenoid valve that influences the fuel quantity to be injected into an internal combustion engine, the duration of the driving of the solenoid valve being correctable by a delay time, characterized in that the delay time can be specified as a function of the instantaneous value of the current to the desired switch-off procedure.

Abstract: A receiving comparator for a data-transmission system comprising at least one control unit and data-transmission lines, in particular for at least one Controller Area Network (CAN) controller and one CAN bus system having a CAN bus (CB) is proposed, which is distinguished by the feature that the individual circuit elements are monolithically integrated. By generating a switching threshold which is independent of the operating voltage and temperature with the aid of a current source (I.sub.S), one prevents the CAN bus potentials from being asymmetrically influenced. The arrangement guarantees a processing of digital signals with a high data rate, whereby the input common-mode range extends up to above the supply voltage and to below ground.

Abstract: A transmitter end stage for a data transmission system comprising at least one control unit and data transmission lines, especially for a CAN bus system having at least one CAN controller and one CAN bus (CB) is proposed, characterized by the fact that the individual circuit elements of transmitter end stage 18 are integrated monolithically. As a result of the special layout and its circuit-design arrangement of the individual elements (3, 5; R1, D1, T1; R2, D2, T2; D10, D20) of the transmitter end stage, the effects of malfunctions, for example of short circuits of the data lines to ground or to the supply voltages, are reduced to a minimum. As a result of the special choice of pre-drivers (3, 5), minimum delay times are achieved, so that signals can be transmitted at a higher data rate.
