User’s Manual 57 Rev. 1.2, 2018-02
To avoid switching due to mechanical vibrations of the rotor, an artificial hysteresis is recommended (Figure 5-20).

1) Depends on internal oscillator frequency variation (see Data Sheet)
2) Not subject to production test - verified by design/characterization
3) GMR hysteresis not considered
4) Minimum hysteresis without switching
5) The hysteresis has to be considered only at change of rotation direction
