Functional Description Unipolar Type TLE4905 Figure 3 and 4

When a positive magnetic field is applied in the indicated direction Figure 3 and the turn-on magnetic induction BOP is exceeded, the output of the Hall-effect IC will conduct Operate Point . When the magnetic field is reduced to a value smaller than the release point, the output of the IC turns off Release Point Figure
