Overview
The MLX90416KLD-AAA-002-SP is a single-coil, Hall-less brushless DC motor driver designed for 24V applications. It supports up to 60W power and features configurable current limits up to 4A with an 8A braking current capability. The integrated half-bridge exhibits a low RDSon of 135 mOhm. Operating voltage ranges from 6.7V to 27.6V, with a junction temperature range of -40°C to 150°C. Speed control is managed via PWM input, providing feedback through a programmable FG output. The device allows for extensive parameter configuration via I2C into non-volatile memory.
Feature Summary
- Hall-less sensorless technology eliminates the need for external magnetic sensors
- Configurable speed curves support both open-loop and closed-loop control modes
- Integrated protection mechanisms include rotor lock, overcurrent, undervoltage, and thermal shutdown
- Non-volatile memory enables multiple reconfigurations via I2C interface
Applications
- 24V industrial fans
- White goods and home appliance cooling systems
- General purpose 24V pumps and blowers
Procurement Notes
Verify the specific suffix '002-SP' against the official Melexis datasheet to confirm blank OTP status and package type. Ensure compatibility with the required programming tools, such as FandriverEVB2 or FandriverProgrammerB, for initial configuration. Confirm RoHS compliance and DFN10 package dimensions match your PCB layout requirements before finalizing procurement.
Selection Notes
Select this component for 24V single-coil BLDC motor applications requiring high efficiency without external Hall sensors. It serves as a direct replacement for traditional sensorless three-phase solutions, reducing bill of materials costs. Choose this part when flexible speed curve configuration and robust protection features are critical for fan or pump reliability in consumer or industrial environments.
Part Context
This device belongs to the MLX90416 series within Melexis's fan driver portfolio. It is specifically engineered for 24V systems, distinguishing it from the 12V-focused MLX90418. The KLD suffix indicates a specific package variant, typically the DFN10 form factor, suitable for compact designs requiring exposed pad thermal management.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility if replacing legacy three-phase drivers or other single-coil alternatives.
