The MLX92211 is the 2nd Gen 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.\nBased 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 is implemented a negative temperature coefficient of -1,100 ppm/degC to compensate the natural behavior of magnets becoming weaker with rise in temperature.\nThe included voltage regulator operates from 2.7 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.\nIn 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.\nThe 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.\nThe 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.\nWith 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.\nThe MLX92211 is delivered in a Green compliant 3-pin TSOT for surface-mount process.\n

The MLX92211 targets applications requiring Hall-effect latch magnetic characteristics. Constructed on a proprietary mixed signal CMOS process technology, the MLX92211 integrate a Hall sensor element with advanced offset cancellation mechanism, a voltage regulator and an open-drain output driver in industry standard 3-pin SIP and TSOT23 packages.\nThe programmable architecture enables high accuracy switching thresholds and an integrated factory programmed thermal compensation value to be set. These features simplify manufacturing of precision, thermally stable sensor modules using low cost magnet materials, while avoiding complex, expensive temperature testing.\nCovering a wide operational voltage range (2.7V to 24V) and supporting an extensive operational temperature range (-40°C to +150°C), these AEC-Q100-qualified devices are highly suited to use in the most demanding of automotive and industrial settings. Output current limit, under-voltage lockout and thermal shutdown ensure on-going reliability, while also lowering the overall bill of materials required. Target automotive applications for the MLX92231 and MLX92211 include seat positioning systems, clutch position sensors, brake light sensors. Both ICs are also suitable for industrial position sensing roles in robotics, factory automation equipment, material handling, valve positions and process controls.\nThe MLX92211 feature a low voltage capability, differentiating them from other Hall-effect sensor solutions on the market, by allowing them to interface with microcontrollers and other digital ICs placed on supply lines at <3V. This maximizes their versatility and permits incorporation into system designs that are beyond the scope of competing devices. The built-in reverse voltage protection feature does not require a serial resistor or diode on the supply line, so that even remote sensors can be specified for low voltage operation down to 2.7V while still being reverse voltage tolerant.\n
