Section 3 - Applications
Introduction
Solid-state switches have been available for many years. In various applications, Hall- Effect Sensors (Hall ICs)
have replaced mechanical contact switches completely. In the mid 1980s the ignition points in automobiles
were replaced by Hall ICs. The automotive market now consumes more than 40 million Hall ICs per year.
Melexis has been manufacturing high quality Hall-Effect Sensors and signal conditioning ASICs for nearly a
decade, and has pioneered the next generation of programmable sensors and sensor interfaces.
This section contains some fundamental information about Hall-Effect sensors, magnetics, and the added value
of programmable sensors and sensor interfaces. It is intended to be useful for the novice as well as the expert.
Design Kit Materials
This section refers to magnets and devices which are included in the Melexis Hall-Effect Sensor Design Kit or
the MLX90308 demo kit. Contents of these kits are listed below. These items can be ordered directly from the
factory by contacting Melexis at (603) 223-2362.

Melexis Reference Magnets
Melexis offers calibrated magnets for use as a reference magnetic field available in 3 ranges. These are for ref-
erence only, and are not calibrated from a traceable source nor are they intended for calibration of any type of
instrumentation. They are intended for programming MLX linear Hall ICs, and for general lab reference.
