Figure 3-2 shows the layout of TIDA-060040.

This layout may be used or adjusted as needed to suit any magnet and motor geometry. While this design includes options for TMAG5170 orthogonal, TMAG5170 at 45° rotation, and DRV5055, it is likewise possible to reduce the PCB layout for a single sensor option as desired.
