2. General Description
The Melexis MLX92221 is a new generation of Hall-effect
switches designed in mixed signal submicron CMOS
technology.
The device integrates a voltage regulator, Hall sensor with
advanced offset cancellation system and a current sinkconfigured output driver, all in a single package.
Based on a brand new 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 a
temperature coefficient is implemented to compensate the
natural behaviour of certain types of magnets becoming
weaker with rise in temperature.

RE (Reel)
The included voltage regulator operates from 2.7 to 24V,
hence covering a wide range of applications. With the builtin 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.

In an event of a drop below the minimum supply voltage
during operation, the under-voltage lock-out protection will
automatically freeze the device, preventing the electrical
perturbation to affect the magnetic measurement circuitry.
The output current state is therefore only updated based on
a proper and accurate magnetic measurement result.
The two-wire interface not only saves one wire, but also
allows implementation of diagnostic functions as reverse
polarity connection and malfunction detection.
The on-chip thermal protection also switches off the output
if the junction temperature increases above an abnormally
high threshold. It will automatically recover once the
temperature decreases below a safe value.
With latching magnetic characteristics the supply current
state is turned high by a sufficiently strong South Pole
facing the package branded side. Toggling the state of the
supply current from high to low is possible by applying low
or no magnetic field.
The MLX92221 is delivered in a Green and RoHS compliant
Plastic Single-in-Line (TO-92 flat) for through-hole mount or
PCB-less design or in 3-pin Thin Small Outline Transistor
(TSOT) for surface mount process
