TLE4905L, TLE4935L, TLE4945L, TLE4945-2L
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 B_OP is exceeded, the output of the Hall-effect IC will conduct (Operate Point).
When the current is reduced, the output of the IC turns off (Release Point; Figure 4).
