To avoid switching due to mechanical vibrations of the rotor, an artificial hysteresis is recommended (Figure 4-18).

1) Depends on internal oscillator frequency variation (Section 4.3.7)

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
