摘要： A receiving circuit is described for a CAN (Controlled Area Network) system with digital data transfer via a bus with parallel, redundant pulse signal transfer via two fines. The receiving circuit includes a comparator circuit assembly for differential evaluation of the two pulse signals received via the two lines, with an offset voltage being superimposed on the pulse signal received via one of the two lines prior to said differential evaluation. The comparator circuit assembly superimposes both a positive offset voltage and a negative offset voltage. A bistable multivibrator circuit is connected between the output side of the comparator circuit assembly and the output of the receiving circuit.

摘要： An electronic system (101/102) for use in a car has an electronic control unit (10) and, in the alternative, either a passive load (11) or an active logic (12) attached thereto. The control unit (10) comprises a push-pull arrangement (20) which can provide drive signals for the load (11) as well as for the logic (12), a multiplexer (45) to alternatively forward a load drive signal of a bus signal to the arrangement (20), and a register (90) to store a mode signal. Further, the control unit (10) automatically determines whether either the load (11) or the logic (12) is attached by analyzing electrical parameters.

摘要： An electric circuit comprising at least one MOS switching transistor disposed on the side of high potential and a switchable charge pump supporting the switching-on phase of the MOS switching transistor at a pumping voltage output thereof with a pumping voltage higher than the potential of the supply voltage on the side of high potential at a pumping voltage output thereof. A control gate of the MOS switching transistor is connectable by means of a controllable switch to a high-potential-side supply voltage terminal or to the pumping voltage output depending on whether a predetermined threshold value on the switching-on ascending edge of the MOS switching transistor signal is exceeded or not.

摘要： A method and circuit configuration for closed-loop control of trigger signals of switching transistors in a resonant converter power supply circuit element having closed-loop control dependent on a zero crossing recognition, wherein a prematurely responding zero crossing detector is provided, includes comparing a period of time between the generation of a trigger signal and the switching of a power transistor with a time interval between a premature response of a zero crossing detector and an actual zero crossing. This is done in order to obtain a closed-loop control signal for controlling a deviation action threshold of the zero crossing detector.
