Overview
The MLX90412KLW-BAA-042-SP is a single-coil fan driver integrated circuit manufactured by Melexis. It operates with a supply voltage range of 3.5V to 32V and delivers an output current of 2.2A. The device supports I2C and PWM interfaces for control. It features flat open-loop operation and includes a feedback generator (FG) output. The component is housed in a DFN-WF-10 package, specifically a 10-DFN (3x3) with exposed pad, designed for surface mount installation.
Feature Summary
- Integrates full control and power stages for single-coil fan applications
- Supports I2C and PWM interface protocols for flexible system integration
- Includes built-in feedback generator for speed monitoring
- Designed for flat open-loop operation modes
Applications
- Consumer electronics cooling systems
- Single-coil fan driving in home appliances
- Industrial blower control units
Procurement Notes
Verify the specific suffix BAA-042-SP against official Melexis documentation to confirm exact configuration parameters. Check RoHS compliance status and moisture sensitivity level requirements before storage and assembly. Confirm export restrictions if shipping from restricted regions. Ensure the DFN-WF-10 package handling guidelines are followed during PCB fabrication.
Selection Notes
Select this component for applications requiring a dedicated single-coil driver with integrated power stages. The 2.2A output capability suits moderate power fan loads. Verify that the 3.5V to 32V supply range matches the system design. Consider the DFN-WF-10 package size constraints for the target enclosure. Confirm compatibility with I2C or PWM control logic levels used in the host controller.
Part Context
This part belongs to the MLX90412 series of motor and motion controllers. It is categorized under PMIC - Power Management ICs within the Motor / Motion / Ignition Controllers & Drivers product line. The series focuses on integrated solutions for fan and pump driving, combining sensing and power delivery in a compact form factor.
Replacement Considerations
Consult official Melexis substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully when considering generic replacements.
