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.
