Magnet Placement
Ideally, the center of the magnet, the diagonal center of the IC and the rotation axis of the magnet should be in one vertical line.
The lateral displacement of the magnet should be within
± 0.25mm from the IC package center or ± 0.5mm from the IC center, including
the placement of the chip within the IC package.
The vertical distance should be chosen such that the magnetic field on the die surface is within the specified limits. The typical
distance “z” between the magnet and the package surface is 0.5mm to 1.8mm with the recommended magnet (6mm x 2.5mm). Larger gaps are
possible, as long as the required magnetic field strength stays within the defined limits.
A magnetic field outside the specified range may still produce acceptable results, but with reduced accuracy. The out-of-range condition will be
indicated, when the AGC is at the limits
(AGC= 0: field too strong;
AGC=63=(3F H ): field too weak or missing magnet.
Figure 32. Bz Field Distribution Along the X-Axis of a 6mm? Diametric Magnetized Magnet
Figure 32 shows a cross sectional view of the vertical magnetic field component Bz between the north and south pole of a 6mm diameter
magnet, measured at a vertical distance of 1mm. The poles of the magnet (maximum level) are about 2.8mm from the magnet center, which is
almost at the outer magnet edges. The magnetic field reaches a peak amplitude of ~± 106mT at the poles.
The Hall elements are located at a radius of 1mm (indicated as squares at the bottom of the graph). Due to the side view, the two Hall elements
at the Y-axis are overlapping at X = 0mm, therefore only 3 Hall elements are shown.
At 1mm radius, the peak amplitude is ~± 46mT, respectively a differential amplitude of 92mT.
The vertical magnetic field B z follows a fairly linear pattern up to about 1.5mm radius. Consequently, even if the magnet is not perfectly centered,
the differential amplitude will be the same as for a centered magnet.
For example, if the magnet is misaligned in X-axis by -0.5mm, the two X-Hall sensors will measure 70mT (@x = -1.5mm) and
-22mt (@x = -0.5mm). Again, the differential amplitude is 92mT.
At larger displacements however, the B z amplitude becomes nonlinear, which results in larger errors that mainly affect the accuracy of the
system (see also Figure 34 )
