Overview
The MLX90416KLD-ABA-004-SP is a single-coil fan driver IC from Melexis, designed for 24V brushless DC motors. It features No-Hall sensor technology with an integrated clamp voltage of 30V and a configurable current limit of 4.0A. The device supports open-loop and closed-loop speed control via PWM input, offering up to 8 configurable points for speed curves. It utilizes blank OTP memory for configuration and operates within a supply voltage range of 6.7V to 27.6V. The package is DFN10 (3.5x3 mm²) with an exposed pad.
Feature Summary
- No-Hall sensor technology for single-coil BLDC motor driving
- Configurable current limit up to 4.0A with 8.0A braking capability
- Integrated power clamp at 30V eliminating external TVS requirements
- Blank OTP memory allowing multiple reconfigurations via I2C
Applications
- 24V industrial fans
- White goods and home appliance cooling systems
- General purpose 24V pumps and blowers
Procurement Notes
Verify the specific suffix 'SP' against official Melexis documentation to confirm it denotes a sample or special packaging variant distinct from standard production reels. Ensure the blank OTP configuration matches project requirements before ordering, as post-programming changes may be limited depending on the exact hardware revision. Cross-reference the DFN10 footprint dimensions with PCB layout guidelines to ensure mechanical compatibility.
Selection Notes
Select this component when designing 24V single-coil fan applications requiring high current handling up to 4A without external sensing components. It is suitable for replacing traditional three-phase solutions in compact designs. Consider the integrated 30V clamp for cost reduction by omitting external TVS diodes. Verify that the required speed control strategy aligns with the available open-loop or closed-loop modes supported by the blank OTP configuration.
Part Context
This part belongs to the MLX90416 series of intelligent fan drivers. It shares the core architecture with variants like MLX90416KLD-ABA-004-RE but differs in packaging and delivery format. The series is characterized by its no-code plug-and-play functionality and robust protection features including rotor lock protection, under-voltage protection, and over-temperature shutdown.
Replacement Considerations
MLX90416KLD-AAA-004-SP is a documented alternative within the same family, differing primarily in bulk packaging versus the specific SP designation. Both share identical electrical specifications including the 30V clamp and 4.0A current limit. Verify package compatibility and OTP programming status before substitution.
