  • Patent number: 11397223
    Abstract: A Hall sensor has a Hall sensor element, which has multiple connection points spaced apart from one another. A supply source serves for feeding an exciter current into the Hall sensor element and is connected to a first and a second connection point of the Hall sensor element. The Hall sensor has a first and a second comparison device. The first comparison device has a first input connected to a third connection point of the Hall sensor element, a second input connected to a reference signal generator for an upper reference value signal, and an output for a first comparison signal. The second comparison device has a third input connected to the third connection point, a fourth input connected to a reference signal generator for a lower reference value signal, and an output for a second comparison signal. The outputs are connected to an evaluation device for generating an error signal as a function of the first and second comparison signal.

  • Patent number: 10845431
    Abstract: A Hall sensor has a Hall sensor element, having multiple connection locations and a current supply source or voltage supply source, which has a first and a second supply connector for output of a supply current or a supply voltage. The first supply connector is connected or can be connected with a first connection location to feed a current into the Hall sensor element, and the second supply connector is connected or can be connected with a second connection location of the Hall sensor element. The Hall sensor has a NAND gate, which is connected with the first connection location of the Hall sensor element using a first input, and with the second connection location of the Hall sensor element using a second input, and has an output for output of a first error signal.

  • Patent number: 10571347
    Abstract: A pressure sensor (10) has a carrier chip (20) in and/or on which at least one sensor element (30) is integrated, the measuring signal of which depends on the mechanical stress in the carrier chip (20). The carrier chip (20) is connected on its back side in a flat and material-locking fashion to a solid body (50), the modulus of elasticity of which differs from the modulus of elasticity of the carrier chip (20). The carrier chip (20) has at least two independent and longitudinal grooves (80a, 80b) between which the sensor element (30a, 30b) is arranged. The pressure sensor has a bias voltage circuit (40) and is used in a common rail injection system.
