MLX90287LZC-AAA-000-SP

Overview

The MLX90287LZC-AAA-000-SP is a Hall effect-based fan driver IC designed for single-coil brushless cooling fans. It operates within a supply voltage range of 4.5 V to 18 V and supports continuous load currents up to 550 mA. The device accepts PWM input signals with frequencies between 100 Hz and 100 KHz, or analog control via potentiometer or thermistor. It features intelligent soft start to suppress peak current and active soft switching for low noise operation. The component is AEC-Q100 qualified and housed in an SODS-8 package.

Feature Summary

Fully integrated Hall effect based solution for driving single-coil brushless fans
Supports speed control via wide-range PWM input or analog signals without external circuitry
Intelligent soft start functionality to ensure reliable startup while suppressing peak current
Active soft switching mechanism for optimized acoustic performance

Applications

Cooling fans for desktop computers
Thermal management in gaming consoles
Automotive LED headlight cooling systems

Procurement Notes

Verify the NRND status before finalizing designs, as this component is not recommended for new designs. Confirm export documentation requirements if shipping from the United States. Ensure the SODS-8 package orientation matches the PCB footprint. Validate that the target application falls within the specified 4.5 V to 18 V operating range and does not exceed the 550 mA continuous current limit.

Selection Notes

Select this component for applications requiring a robust, single-chip solution for 12 V nominal cooling fans. It is suitable for environments demanding operation across -40°C to 150°C. Choose this part when compatibility with Intel PWM specifications is required or when analog temperature-based speed regulation is preferred over digital interfaces. Ensure the design accommodates the specific SODS-8 package constraints.

Part Context

This part belongs to the MLX90287 series of fan drivers manufactured by Melexis. It is categorized under Motor/Motion/Ignition Controllers & Drivers within the PMIC segment. The device is specifically engineered for energy-efficient cooling designs in IT equipment and automotive sectors, providing a complete power stage and control logic in one package.
