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.

Thermal

Protection

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.

2 General Description

The Melexis MLX92241 is a new generation of Hall-

effect switches designed in mixed signal submicron

CMOS technology.

With switching 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 device integrates a voltage regulator, Hall sensor

with advanced offset cancellation system and a current

sink-configured 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.

The MLX92241 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
