7.3.1 Magnetic Flux Direction

As shown in Figure 12, the DRV5057-Q1 is sensitive to the magnetic field component that is perpendicular to the top of the package.

DRV5057-Q1 drv5057-q1-direction-of-sensitivity.gifFigure 12. Direction of Sensitivity

Magnetic flux that travels from the bottom to the top of the package is considered positive in this document. This condition exists when a south magnetic pole is near the top (marked-side) of the package. Magnetic flux that travels from the top to the bottom of the package results in negative millitesla values. Figure 13 shows flux direction.
