As featured device in Melexis' latch & switch program, the MLX92215 offers some key benefits for industrial applications, such as its wide operating voltage range and being cost-effective.
The following serves as a typical application for Melexis latches:

Rotating encoder magnet


Disk magnets are commonly used in index counting applications.
The sensor will be enabled with a South Pole and
disabled with a North Pole.
The sensor will toggle twice for each magnetic pole pair.

For these configurations latch sensors are the best choice as they are operating and releasing with the opposite field.
A direction sensor can be an advantage in case the direction information is requested.




 The 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 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 adition a negative temperature coefficient is implemented to compensate the natural behaviour of magnets becoming weaker with rise in temperature. The included voltage regulator operates from 2.7V 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.
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 it's previous state.
