MLX90411KLD-BAC-029-RE

Overview

The MLX90411KLD-BAC-029-RE is a low-noise, fully integrated single-coil fan driver from Melexis. It features an on-chip Hall effect sensor and supports supply voltages of 5V, 12V, 24V, and 32V. The device provides a maximum motor current of 960mA and includes integrated power clamping options at 20V or 40V to handle back-EMF without external TVS diodes. Designed for consumer applications in IT, home appliances, and industrial equipment, it utilizes a compact UTDFN-6 package (2.5x2.0x0.4mm).

Feature Summary

Integrated high-sensitivity Hall effect sensor eliminates the need for external magnetic components.
Adaptive commutation control optimizes efficiency across the entire operating speed range.
Built-in power clamping protects against voltage spikes from motor back-EMF.
Configurable PWM input with flexible minimum point transfer curves for precise speed control.

Applications

Cooling fans in gaming devices and personal computers
Ventilation systems in household refrigerators and appliances
Thermal management in uninterruptible power supplies (UPS)
Pump drivers in energy storage systems

Procurement Notes

Verify the specific suffix 'BAC' against the official Melexis datasheet to confirm exact electrical parameters and pinout compatibility. Confirm that the UTDFN-6 package matches your PCB footprint requirements. Ensure the selected voltage clamp rating aligns with your system's transient protection needs.

Selection Notes

Select this component for applications requiring a compact solution for single-coil fans under 15W. Choose based on the required current limit (up to 960mA) and the necessary voltage clamp level (20V for 5V/12V systems, 40V for 24V/32V systems). Consider the UTDFN-6 package for space-constrained designs.

Part Context

This part belongs to the MLX90411 family of intelligent fan drivers. It is the consumer-grade variant, distinct from the automotive-grade MLX90411L series which holds AEC-Q100 certification. The KLD suffix indicates the specific configuration and packaging for this consumer application.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other MLX90411 variants carefully, as functional differences exist between consumer and automotive grades.
