    摘要: 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.

    摘要: 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. Alternatively or in addition to the NAND gate, the Hall sensor can have a NOR gate, which is connected with the third connection location using a first input connector, and with the fourth connection location using a second input connector, and has an output connector for output of a second error signal.
