7.3.1 Magnetic Flux Direction

As shown in Figure 14, the DRV5056 is sensitive to the magnetic field component that is perpendicular to the die inside the package.

Figure 14. Direction of Sensitivity

Magnetic flux that travels from the bottom to the top of the package is considered positive. 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.
