The MLX92211 is the second generation Hall-effect latch IC designed in mixed signal CMOS technology. The device has a broad operational temperature range which spans from -40 °C to 150 °C. 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 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 there is a negative temperature coefficient implementing to compensate the natural behavior of the magnetics over temperature.

The included voltage regulator operates from 2.7 V to 24 V, 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 2.7 V while being reverse voltage tolerant.

In the 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 state is therefore only updated based on a proper and accurate magnetic measurement result.

The open drain output is fully protected against short-circuit with a built-in current limit. An additional automatic output shutoff is activated in case of a prolonged short-circuit condition. A self-check is then periodically performed to switch back to normal operation if the short-circuit condition is released.

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 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 MLX92211 is supplied in a choice of either a 3-pin TO-92-Flat for through-hole mount assembly or in 3-pin TSOT for surface mount assembly. The MLX92211 is AEC-Q100 qualified.
