MLX90418KLD-AAA-002-SP

Overview

The MLX90418KLD-AAA-002-SP is a single-coil brushless DC fan driver designed for high-speed server applications. It operates on a 12V supply with a clamp voltage of 22V and supports a configurable current limit up to 2.8A. The device utilizes Hall-less sensor technology for open-loop and closed-loop speed control, offering a maximum speed of 40,000 RPM for two-pole pair motors. It features an integrated half-bridge with low RDSon, providing 8A braking current capability. The chip includes non-volatile memory for multiple I2C configurations and offers protection against locked rotor, undervoltage, overcurrent, and thermal shutdown conditions.

Feature Summary

Hall-less single-coil technology eliminates the need for external sensors
Configurable speed curves and soft-start options for flexible motor control
Integrated power clamp removes the requirement for external TVS diodes
Non-volatile memory allows for repeated reconfiguration via I2C interface

Applications

High-speed server cooling fans
General 12V fans and pumps up to 30W
Replacement for traditional sensorless three-phase solutions

Procurement Notes

Verify the specific suffix 'SP' indicates the standard sampling or production configuration as defined by Melexis. Confirm that the KLD package code corresponds to the required DFN10 footprint. Ensure the blank OTP setting matches the intended default operational parameters without requiring additional programming steps during initial deployment.

Selection Notes

Select this component when designing compact 12V fan systems requiring reduced bill-of-materials complexity compared to three-phase alternatives. It is suitable for applications needing high rotational speeds up to 40,000 RPM and precise speed regulation via PWM input. Consider the integrated protection features for robust operation in demanding thermal environments.

Part Context

This part belongs to the MLX90418 series, which targets the server market with efficient single-coil solutions. It replaces complex three-phase drivers, simplifying design while maintaining performance. The series supports various power levels and integrates advanced diagnostic features for reliable fan management in critical infrastructure applications.
