Overview
The MLX90297LLW-ABF-206-RE is a single-chip fan driver manufactured by Melexis using mixed-signal CMOS technology. It is designed to drive single-coil brushless DC (BLDC) motors. The device operates within a supply voltage range of 3.3 V to 18 V and supports an output current of 960 mA. It utilizes a DFN-WF-10 package for surface mount installation. The component is qualified under the AEC-Q100 standard, ensuring reliability for automotive and consumer applications.
Feature Summary
- Integrates a voltage regulator, Hall sensor with advanced offset elimination, and power H-bridge in a single package.
- Enables efficient motor speed control via PWM input signals applied to the output half-bridge driver.
- Allows configurable speed curves through the adjustment of external resistors.
- Provides robust protection including 9 kV HBM electrostatic discharge (ESD) resistance.
Applications
- Driving single-coil DC brushless motors in consumer electronics
- Fan control systems requiring configurable speed profiles
- Automotive cooling applications compliant with AEC-Q100 standards
Procurement Notes
Verify the specific suffix codes against the official datasheet to confirm pinout and functional configuration. Ensure the selected variant matches the required operating voltage and current specifications for the target BLDC motor application. Confirm package compatibility during PCB layout design.
Selection Notes
Select this component when a compact solution for single-coil BLDC motor driving is required. It is suitable for designs needing integrated magnetic sensing and power output without external discrete components. Consider the DFN-WF-10 footprint constraints and the need for external resistors for speed curve configuration.
Part Context
This part belongs to the MLX90297 family of single-chip fan drivers from Melexis. These devices are engineered to reduce bill of materials costs and PCB size by integrating all necessary functions for fan control into one chip. The family targets both automotive and consumer markets with high integration levels.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if substituting with other MLX9029x variants or different manufacturers' single-coil fan drivers.
