Overview
The MLX90411LZE-BAF-043-RE is a fully integrated fan driver IC from Melexis Technologies, designed for automotive applications. It operates within a supply voltage range of 3V to 28V and features a 40V power clamp. The device supports an output current up to 600mA and is housed in a SOT-23-6 surface-mount package. It includes a built-in high-sensitivity Hall effect sensor for closed-loop speed control with ±1.5% accuracy. The component is AEC-Q100 qualified and operates across a temperature range of -40°C to 150°C TJ.
Feature Summary
- Fully integrated driver with control and power stages
- Built-in high-sensitivity Hall effect sensor
- Integrated 40V power clamp protection
- Closed-loop speed control capability
Applications
- Automotive fan control systems
- Blower motor drivers
- Pump control applications
Procurement Notes
Verify the specific suffix BAF against the official Melexis datasheet to confirm pinout and functional configuration. Ensure compatibility with the target system's voltage requirements, as this variant specifies a 40V clamp. Confirm that the SOT-23-6 package aligns with the PCB footprint design. Check for any export restrictions or humidity sensitivity handling requirements during storage and assembly.
Selection Notes
Select this component when automotive-grade reliability and closed-loop speed regulation are required. The 40V clamp makes it suitable for systems with potential back-EMF spikes exceeding standard limits. Compare against other MLX90411 variants if different current ratings or packaging options like UTDFN are preferred. Ensure the application benefits from the integrated Hall sensor rather than requiring external feedback mechanisms.
Part Context
This part belongs to the MLX90411 series of low-noise single-coil fan drivers. The series offers various configurations for consumer and automotive markets, differing in voltage clamping, current limits, and packaging. The LZE suffix typically denotes the SOT-23-6 package form factor within this family.
Replacement Considerations
Consult the official Melexis cross-reference guide for verified substitutes. Direct replacements must match the SOT-23-6 package, 40V clamp rating, and automotive qualification status.
