MLX90418KLD-AAA-014-RE

Overview

The MLX90418KLD-AAA-014-RE is a single-coil brushless DC fan driver from Melexis, 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 4.0A. The device utilizes No-Hall sensorless technology and features specific LRP (Locked Rotor Protection) settings with blank OTP configuration. It is housed in a DFN10 package.

Feature Summary

Sensorless single-coil architecture eliminating the need for Hall sensors
Configurable speed control via PWM input with programmable feedback output
Integrated protection mechanisms including locked rotor, overcurrent, and thermal shutdown

Applications

High-speed server cooling fans
General 12V fan and pump systems
Single-coil solutions replacing traditional three-phase motors

Procurement Notes

Verify the suffix RE against AAA-014-SP to confirm packaging or tape-and-reel specifications. Ensure the specific LRP configuration matches the target motor requirements. Confirm RoHS compliance status through official documentation before integration.

Selection Notes

Select this model for 12V single-coil BLDC motors requiring up to 4A drive capability. It serves as a cost-effective alternative to three-phase solutions by reducing bill-of-materials complexity. Suitable for applications needing integrated power clamping without external TVS diodes.

Part Context

Part of the MLX90418 series, optimized for server market efficiency. It enables power scaling up to 30W for 4cm and 6cm fans. The chip integrates two half-bridges with low RDSon, supporting braking currents up to 8A.
