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.
