5 General Description

The Melexis MLX92232 is the second generation programmable Hall-effect sensor 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.

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. 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 open drain output is fully protected against short-circuit with a built-in current limit. An additional automatic

output shut-off 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.

Furthermore the MLX92232 features a full set of programmable parameters that can be adjusted in the application in order

to achieve the highest possible system accuracy by compensating the mechanical tolerances.

An Integrated Magnetic Concentrator option (IMC) has been added to sense the lateral field component. This is adding more

flexibility in the module design. A dual die option is also available for applications that need a secondary output; these can be

programmed independently from each other.
