Overview
The MLX90419KLD-AAA-004-SP is a single-coil fan driver from Melexis, designed for automotive applications. It operates with a supply voltage range of 6.7 V to 18 V and delivers an output current of 2.4 A at an output voltage of 20 V. The device features a clamp voltage of 29 V and utilizes a No-Hall sensor architecture. Packaged in SMD/SMT format, it includes blank OTP memory for customization. This component serves as a motor controller and driver within the MLX90419 series.
Feature Summary
- Single-coil fan driver architecture optimized for direct motor control
- No-Hall sensor integration eliminates external magnetic sensing requirements
- Blank OTP memory allows for flexible configuration during manufacturing
Applications
- Automotive cooling fan systems
- Motor motion control circuits
- Ignition system drivers
Procurement Notes
Verify the specific suffix 'SP' against official Melexis documentation to confirm tape and reel packaging details. Ensure the 2.4 A output current rating aligns with your thermal management design. Cross-reference the 29 V clamp voltage with your load specifications to prevent overvoltage conditions. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement.
Selection Notes
Select this component when a single-output high-current drive is required without Hall sensor feedback. The 6.7 V to 18 V input range suits standard automotive electrical environments. Consider the SMD package for automated assembly processes. Verify that the 2.4 A continuous current capability meets the peak and steady-state demands of the target fan or motor load.
Part Context
This part belongs to the MLX90419 series of motor controllers and drivers by Melexis Technologies NV. The series focuses on integrated solutions for automotive thermal management and ignition applications. The KLD suffix typically indicates a specific package type and temperature grade, while AAA denotes the functional variant. The SP suffix often signifies a specific shipping or packaging configuration.
Replacement Considerations
Check for MLX90419KLD-AAA-002-SP as a potential alternative within the same series. Verify pin compatibility and electrical parameters such as output current and voltage ratings. Ensure the replacement maintains the No-Hall architecture if sensorless operation is required. Consult official substitution guides for any functional differences.
