MLX90297LLW-AAF-206-SP

Overview

The MLX90297LLW-AAF-206-SP is a single-coil fan driver from Melexis, designed for consumer applications. It operates on a supply voltage range of 3.3V to 18V and features an output current limit of 800mA. The device supports PWM control with a working frequency range of 100Hz to 100kHz. Packaged in an SODS-8 format, it is AEC-Q100 qualified and utilizes straight leads for surface mount installation.

Feature Summary

• Single-coil fan driver architecture optimized for low noise operation
• Configurable speed curve via internal state machine without code
• Integrated thermal protection and diagnostic capabilities

Applications

• Consumer cooling fans
• Small appliance ventilation systems
• HVAC unit auxiliary fans

Procurement Notes

Verify the specific suffix 'AAF' against the official datasheet to confirm lead type and package orientation. Confirm that the 'NRND' status does not impact existing production schedules. Ensure ESD handling protocols are followed during assembly due to the sensitive input stages.

Selection Notes

Select this component when a robust, single-coil solution is required for 12V or 24V fan systems. The integrated current limiting protects against stall conditions. Consider the SODS-8 package for compact PCB layouts where through-hole mounting is not feasible but high reliability is needed.

Part Context

This part belongs to the MLX90297 series of intelligent fan drivers. It simplifies motor control by integrating the power stage and logic into a single chip. The series targets cost-sensitive consumer markets while maintaining automotive-grade reliability standards through AEC-Q100 qualification.
