Overview
The MLX90412GLW-BAA-042-RE is a fully integrated automotive fan driver IC from Melexis, designed for single-coil applications. It operates with a supply voltage range of 3.5V to 32V and delivers an output current of 2.2A. The device supports I2C and PWM interfaces for control. It features a flat open-loop configuration with a fault guard (FG) function and is rated for junction temperatures up to 160°C. Packaged in a 10-DFN (3x3 mm) surface-mount package with wettable flanks, it meets AEC-Q100 automotive qualification standards.
Feature Summary
- Fully integrated control and power stage for single-coil fan drivers
- Supports I2C and PWM interface protocols for flexible system integration
- Includes Fault Guard (FG) functionality for enhanced system safety
- Designed for high-temperature operation with a 160°C junction temperature rating
Applications
- Automotive cooling fan control systems
- Engine compartment thermal management
- High-temperature motor driver applications requiring open-loop control
Procurement Notes
Verify the specific suffix 'GLW' against the official Melexis datasheet to confirm the exact electrical characteristics and packaging details. Ensure compatibility with the target vehicle's communication protocol requirements. Confirm that the 160°C thermal rating aligns with the application's environmental constraints. Check for any export restrictions or additional documentation required for procurement in your region.
Selection Notes
Select this component when a robust, automotive-grade solution for single-coil fans is required. It is suitable for applications needing precise digital control via I2C or simple PWM signals. Consider the 10-DFN package size for space-constrained PCB layouts. Verify that the 2.2A output current meets the load requirements of the intended fan motor.
Part Context
This part belongs to the MLX90412 series of automotive fan drivers. It is distinct from variants like the LLW model, which may offer different control loops or temperature ratings. The GLW suffix typically denotes specific performance characteristics within the family. It serves as a dedicated driver for managing cooling fans in demanding automotive environments.
Replacement Considerations
Consult the official Melexis replacement guide for verified substitutes. Direct pin-to-pin replacements must match the 10-DFN package and electrical specifications. Generic equivalents are not recommended due to strict automotive reliability standards.
