    摘要： The transceiver features a fast de-excitation circuit, by means of which the transceiver can be very quickly de-energized or de-excited after sending of signals. The fast de-excitation circuit can be realized in the simplest case as a controllable switch with series-connected resistor. The transceiver is thus ready to receive signals again very fast, i.e. in the range of a few oscillation periods. With bidirectional data communication between transceiver and transponder the danger of malfunctions is avoided or at least reduced to a minimum level.

    摘要： A transmitter unit generates a carrier signal in the form of a periodic bipolar signal. The carrier signal has intrapulse periods between two pulses of different polarity. A transmission antenna is operated with the bipolar signal. To prevent the harmonic oscillations of the transmitted signals from having excessively great amplitudes, the intrapulse period is defined such that the amplitude of the first harmonic of the transmitted oscillation, ascertained by Fourier analysis, is greater than 90% and the amplitude of the third harmonic oscillation is less than 25%, in comparison with the amplitude of the fundamental oscillation of a rectangular oscillation without intrapulse periods.

    摘要： A circuit with switchable functionality has a first integrated circuit, which has, in a first operating mode, full functionality and which has, in at least one other operating mode, a functionality which is reduced in comparison with the full functionality. The circuit further has an output terminal to which a coupling element can be coupled, an identification device which identifies whether a first supply potential has been applied to the output terminal via the coupling element and in this case produces a status signal with a first value and otherwise produces a status signal with a second value, a setting device, which sets the full or reduced functionality as a function of the value of the status signal in the first integrated circuit. The invention also relates to an electronic component having such a circuit arrangement.

    摘要： A method and a device for an open-load diagnosis of a switching stage includes the steps of turning off the switching transistor if, after a first delay time has elapsed since an appearance of a control signal, the output voltage is less than a first reference voltage, and if, after a second delay time has elapsed, the output voltage is less than a second reference voltage, then, with the switching transistor in the on state again, comparing the output current flowing through the switching transistor with a reference current, and if the output current is less than the reference current, effecting an open-load indication. The device includes a switchable buffer amplifier; a switching transistor, second and third transistors, a reference current source, first and second comparators, and a control circuit connected to the buffer amplifier, to the second and third transistors, and to the first and second comparators.

    摘要： Actuator configuration, in particular, for actuating an injection valve of an internal combustion engine, includes an electrically activated actuator, a power switch for activating the actuator, a control input for receiving a control signal for actuating the power switch from an external control unit through a control line, and a diagnostic circuit connected at an input end to the actuator and/or to the power switch. For sensing the operating state, the control input is connected to at least a switching element in order to influence the electrical input characteristics, and the diagnostic circuit is connected at the output end to the switching element in order to influence the input characteristics as a function of the operating state and, as a result, to permit remote diagnostics by the external control unit through the control line. A method for actuating an injection valve of an internal combustion engine is also provided.

    摘要： Electrical consumers receive load current from a supply voltage via two or more power switches. A false-closure detection device includes a measuring device and a diagnostic device for the detection of faults. The measuring device is connected parallel to the power switches and the electrical consumer lying in series with the switches. A diagnostic voltage is compared as the output signal of the measuring device with a reference value for the detection of false closures in the load circuit.
