3.7. Magnetic Characteristics at TJ = –40 °C to +140 °C, VDD = 4.5 V to 24 V,
Typical Characteristics for VDD = 12 V
Magnetic flux density values of switching points.
Positive flux density values refer to the magnetic south pole at the branded side of the package.

Note: For detailed descriptions of the individual types, see pages 10 and following.
The magnetic limits given above refer to parts in the original packaging. Mechanical stress on the hall sensitive areas
on the chip surface may generate an additional magnetic offset, which can slightly change the magnetic switching
points. This behavior is a physical phenomenon and not a malfunction of the sensor. Mechanical stress on the hall plates
can be caused, for example, by overmoulding the plastic package or by wide range temperature changes like soldering
or operating the parts at extreme temperatures.
Please use a sensor of the HAL 5xx family if higher robustness against mechanical stress is required.
