Overview
The MLX90412LLW-BAC-042-RE is a fully integrated fan driver IC designed for automotive applications. It features a single coil fan driver with feedback (FG) capability, supporting up to 40V supply and 2.2A output current. The device operates in open-loop mode with 1/16 step resolution. It utilizes I2C and PWM interfaces for control. The component is qualified to AEC-Q100 standards and housed in a 10-DFN (3x3mm) package with exposed pad and wettable flank soldering.
Feature Summary
- Fully integrated control and power stage for single coil fans
- Supports I2C and PWM digital interfaces
- Includes feedback (FG) signal monitoring
- Qualified for automotive environments
Applications
- Automotive cooling fan control
- Engine compartment thermal management
- HVAC system fan drivers
Procurement Notes
Verify the specific suffix BAC against the official Melexis datasheet to confirm pinout and functional compatibility. Ensure the 10-DFN package dimensions match the PCB footprint. Confirm AEC-Q100 qualification status for the target automotive application requirements before finalizing procurement.
Selection Notes
Select this component when a single high-current fan driver with digital interface is required. The 2.2A output rating suits medium-to-large automotive cooling fans. The 1/16 step resolution provides precise speed control. Consider the 10-DFN package size for space-constrained designs requiring wettable flank visibility for inspection.
Part Context
This part belongs to the MLX90412 series of automotive fan drivers from Melexis. The series offers integrated solutions for controlling DC fans in harsh automotive environments. The LLW variant indicates specific packaging and tape/reel configuration suitable for automated assembly processes.
Replacement Considerations
Check for MLX90412LLW-BAA-042-RE as a potential alternative within the same family, verifying if the BAA suffix denotes identical electrical characteristics and pinout compatibility for direct replacement.
