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.
