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.

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 magnetic field is reduced to a value smaller than the release
point, the output of the IC turns off (Release Point; Figure
4).
