Sensors Location and Placement Tolerances

Figure 6-2 shows the location of the AMR sensor and X, Y Hall elements, along with the placement tolerances inside the TMAG6181-Q1.

GUID-20230914-SS0I-3N78-BZZZ-V11SSSWQ9RGN-low.svg Figure 6-2 Location of AMR Sensor and Hall Elements

The center of the AMR and Hall sensors lie in the center of the package. Figure 6-3 shows the tolerances of the die rotation within the package. This causes a reference angle error (Φ) of ± 3°.
