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.
