TLE4905L, TLE4935L, TLE4945L, TLE4945-2L Circuit Description The circuit includes Hall generator, amplifier and Schmitt-Trigger on one chip. The internal reference provides the supply voltage for the components. A magnetic field perpendicular to the chip surface induces a voltage at the hall probe. This voltage is amplified and switches a Schmitttrigger with open-collector output. A protection diode against reverse power supply is integrated. The output is protected against electrical disturbances.
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 BOP 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).
TLE4905L, TLE4935L, TLE4945L, TLE4945-2L 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 BOP 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 BRP is exceeded. In this case the output will turn off (Release Point; Figure 6).
