Definitions
- Equation (2) can be easily determined using an A / D
- the direction of the current flowing through the vertical Hall elements is the same for all vertical Hall elements, since a reversal of the current direction corresponds to an angle change from ⁇ m to ⁇ m + 180 °.
- the direction of the stem is shown by an arrow in the four magnetic field sensors.
- Such a magnetic field sensor can be used, for example, in an angle transmitter, where the magnetic field sensor rotates about an axis relative to a magnet. In this case, it makes sense to align the vertical Hall elements symmetrically to an axis running perpendicular to the surface of the semiconductor chip, which axis coincides with the axis of rotation of the angle encoder in the installed state.
