MLX90411KZE-BAB-026-RE

Overview

The MLX90411KZE-BAB-026-RE is a single-coil fan driver from Melexis, designed for consumer applications. It features an integrated high-sensitivity Hall effect sensor and supports supply voltages of 5V, 12V, and 24V. The device provides a maximum motor current of 660mA and includes a 20V power clamp to handle back EMF without external TVS diodes. Packaged in a surface-mount SOT-23-6 housing, it offers open-loop speed control with adaptive commutation for low acoustic noise and high efficiency across the operating range.

Feature Summary

• Integrated high-sensitivity Hall effect sensor for precise commutation
• Built-in 20V power clamp eliminates need for external transient voltage suppressors
• Adaptive commutation ensures low acoustic noise and high efficiency
• Supports open-loop speed control with programmable dynamic PI settings

Applications

• Consumer electronics cooling fans
• Home appliance blowers
• Industrial pump drives
• Small DC motor applications under 15W

Procurement Notes

Verify component authenticity through authorized Melexis distributors or certified partners. Confirm package integrity and pin alignment against the SOT-23-6 specification sheet prior to assembly. Ensure ESD handling protocols are followed during storage and placement. Cross-reference the ordering suffix with the specific electrical configuration required for the target application voltage and current limits.

Selection Notes

Select this variant when a 20V clamp rating is sufficient for the system's back EMF requirements. The 660mA output current suits loads below 15W. Choose the SOT-23-6 package for standard surface-mount reflow processes. This model targets consumer-grade environments rather than automotive AEC-Q100 certified applications. Validate that the open-loop control strategy meets the specific speed regulation needs of the fan design.

Part Context

This part belongs to the MLX90411 family of single-coil fan drivers. It shares core architecture with other variants differing in voltage clamping levels (20V vs 40V) and current limits. The KZE suffix indicates the SOT-23-6 package type. It is distinct from the automotive-grade L-series parts which carry AEC-Q100 certification and wider temperature ranges.

Replacement Considerations

MLX90411KZE-BAA-026-RE: Similar 20V clamp and 660mA current but may differ in FG/RD output configurations.
