Overview
The MLX90412LLW-BAA-045-RE is an automotive-grade, single-coil fan driver from the Melexis MLX90412 series. It integrates a high-sensitivity Hall effect sensor and power stage for open-loop speed control. The device operates within a supply voltage range of 3.5 V to 40 V and supports a current limit of 1.5 A. It features adaptive commutation for low acoustic noise and high efficiency across the full speed range. The component utilizes I2C and PWM interfaces for configuration and control, housed in a compact 10-DFN (3x3 mm) package.
Feature Summary
- Integrates a high-sensitivity Hall effect sensor with a fully integrated power stage for single-coil motor driving.
- Features adaptive commutation technology to minimize acoustic noise and maximize efficiency throughout the operating range.
- Supports flexible control via I2C interface and PWM input for open-loop speed regulation.
Applications
- Automotive cabin ventilation fans
- Engine cooling system blowers
- Thermal management pumps
Procurement Notes
Verify the specific suffix -045-RE against the official datasheet to confirm the exact current limit and packaging details. Note that this part number carries an NRND (Not Recommended for New Designs) status; alternative models within the MLX90412 family should be evaluated for long-term availability and support before finalizing procurement plans.
Selection Notes
Select this component for applications requiring robust automotive reliability and low-noise operation in single-coil fan systems. Ensure the design accommodates the 3.5 V to 40 V supply range and 1.5 A current capability. Verify that the 10-DFN footprint fits the PCB layout constraints and that thermal dissipation requirements are met under maximum load conditions.
Part Context
This device belongs to the MLX90412 series, designed specifically for automotive thermal management. It replaces discrete solutions by integrating sensing, control logic, and power drivers into a single chip. The series is characterized by its ability to handle high voltages and currents while maintaining precise speed control through digital interfaces.
Replacement Considerations
Consult the MLX90412 product flyer for direct substitutes. Potential alternatives include other variants within the MLX90412 family with different current ratings or packaging options, provided they meet the same automotive qualification standards.
