The MLX92211 is a hall-effect latch designed in mixed signal CMOS technology. The device integrates a voltage regulator, hall sensor with advanced offset cancellation system, automotive qualified EEPROIM and an open-drain output driver, all in a single package.
Based on the existing robust 922xx platform, the magnetic core has been equipped with a non-volatile memory that is used to accurately trim the switching thresholds and define the needed output magnetic characteristics (TC, Bop, Brp, Output pole funcionality).
In addition to that an ID has been integrated on the IC to have a complete traceability throughout the process flow.
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.
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 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.
