MLX90412KLW-BAA-025-RE

Overview

The MLX90412KLW-BAA-025-RE is a single-coil fan driver from Melexis, designed for consumer applications. It integrates a high-sensitivity Hall effect sensor and power stage within a DFN-WF-10 package. The device supports open-loop control with a maximum output current of 1.5A and operates at a supply voltage up to 20V. It features an integrated power clamp to handle back-EMF without external TVS diodes. The component is surface-mountable and includes frequency generator outputs for speed monitoring.

Feature Summary

Integrated single-coil fan driver with built-in Hall sensor
Open-loop control architecture for simplified implementation
Integrated power clamp eliminates need for external protection components
Frequency generator output enables rotational speed detection

Applications

Consumer electronics cooling fans
Household appliance blowers
Small pump motor control

Procurement Notes

Verify the obsolete status (NRND) before integration into new designs. Confirm that the 20V rating aligns with system requirements, as higher voltage variants exist. Ensure the DFN-WF-10 package footprint matches PCB layout constraints. Check export compliance documentation if shipping from restricted regions.

Selection Notes

Select this model for low-noise, cost-sensitive consumer applications requiring up to 1.5A drive current. Choose over automotive versions when AEC-Q100 qualification is unnecessary. Consider the 40V variant if operating voltages exceed 20V or if transient spikes are significant. Verify interface compatibility with host controller PWM signals.

Part Context

Part of the MLX90412 series, which offers integrated sensing and driving solutions for small motors. The KLW suffix indicates specific pinout and packaging configuration. This series targets the consumer market with optimized noise and efficiency profiles compared to industrial counterparts.
