MLX90418KLD-AAA-014-SP

Overview

The MLX90418KLD-AAA-014-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 4.0A. The device features No-Hall sensor technology, enabling open-loop and closed-loop speed control without external sensors. It offers eight configurable points for speed curves and supports speeds up to 40,000 RPM for two-pole pair motors. The component functions within a supply voltage range of 6.7V to 18V and withstands junction temperatures from -40°C to +150°C.

Feature Summary

No-Hall sensor technology eliminates the need for external Hall effect sensors
Configurable current limit up to 4.0A with 8.0A braking current support
Eight-point programmable speed curve configuration via I2C interface
Integrated protection against locked rotor, overcurrent, and thermal shutdown

Applications

High-speed server cooling fans
General 12V fans and pumps up to 30W
Single-coil BLDC motor solutions replacing traditional three-phase designs

Procurement Notes

Verify the specific OTP configuration and package variant (KLD) matches the design requirements. Confirm that the 22V clamp rating is sufficient for the target motor's back-EMF characteristics. Ensure the I2C programming tools are available for final configuration before deployment.

Selection Notes

Select this component for applications requiring high-speed performance in compact server environments. It is suitable where reducing bill-of-materials cost by eliminating Hall sensors is critical. Consider the 4.0A current limit and 22V clamp when matching motor specifications.

Part Context

This part belongs to the MLX90418 series, which focuses on single-coil fan drivers for server markets. It provides a cost-effective alternative to three-phase solutions while maintaining high efficiency and speed control precision through advanced signal processing.
