TLE4905/35/45-2 (Unipolar/Bipolar Magnetic Field Switches) have been designed
specifically for automotive and industrial applications. Reverse polarity protection is
included on-chip as is output protection against negative voltage transients.
Typical applications are position/proximity indicators, brushless DC motor commutation,
rotational indexing etc.

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 BOP 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).

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