Functional Diagram 2. General Description VDD The Melexis MLX92211 is the second generation Hall- effect latch designed in mixed signal CMOS technology. Voltage Regulator Under- with Reverse Polarity Voltage The device integrates a voltage regulator, Hall sensor with Protection Lockout advanced offset cancellation system and an open-drain Temperature Bop/Brp Thermal output driver, all in a single package. Based on a brand Compensation reference Protection new platform, the magnetic core is using an improved offset cancellation system allowing faster and more Switched OUT Open-Drain Hall Output accurate processing while being temperature insensitive Plate CDS Amplifier and stress independent. In addition is implemented a negative temperature coefficient to compensate the Current Control Limit & natural behaviour of magnets becoming weaker with rise Auto-Shutoff in temperature.

With the circuit with a built-in current limit. An additional built-in reverse voltage protection, a serial resistor or automatic output shut-off is activated in case of a diode on the supply line is not required so that even prolonged short-circuit condition. A self-check is then remote sensors can be specified for low voltage operation periodically performed to switch back to normal down to 2.7V while being reverse voltage tolerant. operation if the short-circuit condition is released. The on-chip thermal protection also switches off the In the event of a drop below the minimum supply voltage output if the junction temperature increases above an during operation, the under-voltage lock-out protection abnormally high threshold. It will automatically recover will automatically freeze the device, preventing the once the temperature decreases below a safe value. electrical perturbation to affect the magnetic measurement circuitry. The output state is therefore only With latching magnetic characteristics, the output is updated based on a proper and accurate magnetic turned low or high respectively with a sufficiently strong measurement result. South or North pole facing the package top side. When removing the magnetic field, the device keeps its previous state. 390109221101 Page 2 of 16 Datasheet Rev. 010 www.melexis.com December/19
