5 TLE495G; TLE4935G; 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 Schmitt-trigger with open-collector output. A protection diode against reverse power supply is integrated. The output is protected against electrical disturbances.

6 TLE495G; TLE4935G; Functional Description Unipolar Type TLE495 (Figure 3 and 4) When a positive magnetic field is applied in the indicated direction (Figure 3) and the turn-on magnetic induction OP 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 4).

7 TLE495G; TLE4935G; Functional Description ipolar Type TLE4935/35-/45- (Figure 5 and ) When a positive magnetic field is applied in the indicated direction (Figure 5) and the turn-on magnetic induction 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 RP is exceeded. In this case the output will turn off (Release Point; Figure ).
