Functional Description Bipolar Type TLE4935/45-2 (Figure 5 and 6)
When a positive magnetic field is applied in the indicated direction (Figure 5) and the
turn-on magnetic induction B_OP is exceeded, the output of the Hall-effect IC will conduct
(Operate Point). The output state does not change unless a reverse magnetic field
exceeding the turn-off magnetic induction |B_RP| is exceeded. In this case the output will
turn off (Release Point; Figure 6).
