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.

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
