Functional Description Bipolar Type TLE4935/45/45-2 (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
iinduction B_RP is exceeded. In this case the output will turn off (Release Point; Figure 6).
