MLX90287LLD-AAA-000-SP

Overview

The MLX90287LLD-AAA-000-SP is a fully integrated Hall effect-based fan driver IC designed for energy-efficient cooling fan applications. It supports single-coil brushless fans with an operating supply voltage range of 4.5 V to 18 V and can drive continuous currents up to 550 mA. The device accepts PWM input frequencies from 100 Hz to 100 kHz or analog signals for speed control. It features intelligent soft start to suppress peak current and active soft switching for low noise operation. The component operates within a temperature range of -40°C to 150°C and is housed in an 8-pin SOIC package.

Feature Summary

Fully integrated power stage and control logic for single-coil brushless fans
Supports PWM, analog, and temperature-based speed control methods
Intelligent soft start mechanism ensures reliable fan startup while limiting peak current
Active soft switching functionality optimizes acoustic performance across all operating conditions

Applications

Desktop computer cooling systems
Gaming console thermal management
Automotive LED headlight cooling fans
Industrial and aerospace harsh environment cooling

Procurement Notes

Verify the obsolete status indicated by Mouser before procurement planning. Confirm availability through authorized distributors as standard stock may be limited. Ensure the 8-pin SOIC package variant matches the target PCB footprint. Validate that the 4.5 V to 18 V supply range aligns with system requirements. Check for any specific automotive qualification certifications required for the end application.

Selection Notes

Select this component for applications requiring robust control of single-coil fans without external circuitry. It is suitable for environments demanding wide temperature tolerance up to 150°C. Choose this part when low noise operation and precise speed regulation via PWM or analog signals are critical. It addresses most standard 12 V fan applications due to its 550 mA continuous drive capability.

Part Context

This device belongs to the MLX90287 series of fan driver ICs. It serves as a specialized solution for cooling fans in IT equipment and automotive sectors. The series focuses on integrating power and control functions into a single chip to simplify design and improve reliability in speed-controlled fan applications.
