Overview
The MLX90297KLD-SAF-308-RE is a single-chip fan driver designed for driving single-coil DC brushless motors (BLDC). It utilizes mixed-signal CMOS technology and integrates a voltage regulator, Hall sensor with advanced offset elimination, and a power output H-bridge. The device controls motor speed via PWM input signals through the half-bridge driver's switching action. It supports a wide operating voltage range from 3.3 V to 18 V and features configurable speed curves adjusted via external resistors.
Feature Summary
- Integrates voltage regulator, Hall sensor, and power H-bridge in a single package
- Enables efficient speed control through PWM input signal processing
- Allows speed curve configuration via external resistor adjustment
- Complies with AEC-Q100 standards for automotive reliability
Applications
- Single-coil DC brushless motor drives
- Automotive cooling fan systems
- Consumer appliance fan drivers
Procurement Notes
Verify the specific suffix 'SAF-308-RE' against official Melexis documentation to confirm exact factory programming parameters and packaging specifications. Ensure compatibility with the required supply voltage range of 3.3 V to 18 V for the target application design.
Selection Notes
Select this component when a low BOM cost and compact single-layer PCB design are required for single-coil BLDC applications. The integrated solution eliminates the need for discrete components, reducing size while maintaining high magnetic sensitivity and robust operation under varying electrical conditions.
Part Context
This part belongs to the MLX90297 series of single-chip fan drivers manufactured by Melexis. The series is characterized by its ability to drive single-coil fans efficiently using mixed-signal CMOS technology, offering a complete solution within a small footprint suitable for space-constrained environments.
Replacement Considerations
Consult official substitution lists for direct replacements. Generic equivalents may not replicate the integrated Hall sensor offset elimination or the specific AEC-Q100 compliance characteristics of the original component.
