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.
