Method for operating a hall sensor arrangement and hall sensor arrangement

摘要

According to a method for operating a Hall sensor assembly, at least two values (I1, I2) of an input signal (I) of a Hall sensor (11) of the Hall sensor assembly (10) having different magnitudes are set and the associated values (V1, V2) of an output signal (V) of the Hall sensor (11) are determined. Furthermore, a residual offset value (k, VOFF) of the output signal (V) is determined according to the values (V1, V2) of the output signal (V) that were determined at the at least two values (I1, I2) of the input signal (I).

1. A method for operating a Hall sensor arrangement, comprising:
setting at least two different values of an input signal of a Hall sensor of the Hall sensor arrangement that differ with respect to their amount and determining the associated values of an output signal of the Hall sensor, wherein the output signal is only provided after the complete execution of the phases of a cycle of the current spinning technique and the value of the input signal is constant during the phases of the cycle of the current spinning technique such that a first value of the output signal is measured at a first value of the input signal and a second value of the output signal is measured at a second value of the input signal; and determining a residual offset value of the output signal in dependence on the values of the output signal that were determined at the at least two values of the input signal.
