MLX90287KZC-AAA-000-RE

Overview

The MLX90287KZC-AAA-000-RE 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 PWM input frequencies from 100 Hz to 100 KHz. The device integrates a power stage capable of driving loads up to 550 mA continuous current. It features intelligent soft-start functionality to suppress peak inrush currents and ensure reliable startup. The component is housed in an 8-pin SOIC package and is rated for operation 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 brushless fans
• Directly accepts wide PWM frequency inputs without external circuitry
• Intelligent soft start mechanism suppresses start peak current while ensuring reliable fan startup
• Active soft switching capability optimizes noise performance under all operating conditions

Applications

• Desktop computer cooling systems
• Gaming console thermal management
• Automotive LED headlight cooling fans

Procurement Notes

Verify the specific suffix configuration against official Melexis documentation, as packaging variations exist between bulk and reel formats. Confirm availability status prior to design finalization due to potential lifecycle changes. Ensure the selected variant matches the required pinout and thermal characteristics for the target PCB layout. Cross-reference the datasheet revision date to guarantee compliance with current technical specifications.

Selection Notes

Select this component when designing energy-efficient cooling solutions requiring robust integration. It is suitable for applications demanding flexible speed control via digital or analog signals. The wide operating voltage range accommodates standard 12V systems. Consider the integrated protection features and broad temperature rating for harsh industrial or automotive environments where reliability is critical.
