  • Patent number: 11621553
    Abstract: An electrical assembly (100) having a first ground connection (145), a second ground connection (155), and a supply connection (135). The electrical assembly is designed for connecting with an electrical voltage between the supply connection (135) and at least one of the ground connections (145, 155). The assembly (100) includes a first electrical consumer (110) which is connected to the supply connection (135) and the first ground connection (145). A component (120) connects the second ground connection (155) to the first consumer (110). The component (120) is designed to produce a predetermined voltage drop.

  • Patent number: 11581891
    Abstract: A vehicle analog comparator circuit for communication interfaces designed to detect an actuation of an actor. The circuit comprises a unit for producing a supply voltage for supplying the actor, a unit for producing a reference voltage to be compared with the supply voltage, a transistor input stage, a node point EDMx between the actor, the unit for producing a supply voltage and the transistor input stage, and a digital evaluation unit to process the output signal from the transistor input stage such that whether or not the actor is actuated is detected. The transistor input stage comprises a transistor circuit with a first transistor is connected to the node point EDMx, and a second transistor connected to the reference voltage. A collector resistance for limiting the collector current of the second transistor, as well as a base resistance for the two transistors. Alternatively, a current mirror is provided.

  • Patent number: 7596442
    Abstract: In a motor vehicle control unit having a digital control circuit for controlling the electric current, in a way which is robust with respect to the voltage ripple of a vehicle on-board power system, of a control magnet valve for a motor vehicle hydraulic device with simultaneously improved dynamic behavior in response to jumps in a setpoint value current as a reference variable of the control circuit, at least one adaptive correction filter whose filter time can be adjusted dynamically on the basis of the change in level of the setpoint value current is provided in the feedback branch of the digital control circuit.
