MLX90287LZC-AAA-000-RX

Overview

The MLX90287LZC-AAA-000-RX is a Hall effect-based fan driver IC designed for single-coil brushless cooling fans. It operates within a supply voltage range of 4.5 V to 18 V and supports continuous drive currents up to 550 mA. The device accepts PWM input signals with frequencies ranging from 100 Hz to 100 KHz, or analog control via potentiometer or thermistor. It features intelligent soft start to suppress peak current and active soft switching for noise reduction. The component is housed in an SODS-8 package and functions across an ambient temperature range of -40°C to 150°C.

Feature Summary

• Fully integrated Hall effect based solution for low noise speed-controlled single-coil fans
• Directly accepts wide frequency PWM inputs without external circuitry
• Intelligent soft start mechanism ensures reliable fan startup while suppressing peak current
• Active soft switching functionality optimizes acoustic performance under all conditions

Applications

• Desktop computer cooling systems
• Gaming console thermal management
• Automotive LED headlight cooling
• Industrial equipment ventilation

Procurement Notes

Verify the NRND (Not Recommended for New Designs) status before finalizing any new product development plans. Confirm that the specific ordering suffix matches the required lead frame and reel specifications. Ensure compliance with export documentation requirements if shipping from the United States. Check RoHS and halogen-free certification details against current regulatory standards. Validate that the SODS-8 package orientation aligns with the target PCB footprint design.

Selection Notes

Select this component when driving single-coil fans requiring robust protection and flexible speed control. It is suitable for applications demanding operation across extreme temperatures from -40°C to 150°C. Choose this part for designs needing direct PWM integration without additional signal conditioning circuits. Consider the 550 mA continuous drive capability for standard 12V fan loads. Evaluate the soft-start feature necessity for systems sensitive to inrush current spikes.
