output driver, all in a single package. Based on the
existing platform, the magnetic core is using an improved
offset cancellation system allowing faster and more
accurate processing while being temperature insensitive
and stress independent. In addition is implemented a
negative temperature coefficient to compensate the
natural behaviour of magnets becoming weaker with rise
in temperature.

Amplifier
The included voltage regulator operates from 2.7 to 24V,
hence covering a wide range of applications. With the
built-in reverse voltage protection, a serial resistor or
diode on the supply line is not required so that even
remote sensors can be specified for low voltage operation
down to 2.7V while being reverse voltage tolerant.

2 General Description
With latching magnetic characteristics, the output is
turned low or high respectively with a sufficiently strong
South or North pole facing the package top side. When
removing the magnetic field, the device keeps its previous
state.
The Melexis MLX92215 is the second generation Hall-
effect latch designed in mixed signal CMOS technology.
The device integrates a voltage regulator, Hall sensor with
advanced offset cancellation system and an open-drain
