Overview
The MLX90411KZE-BAB-046-RE is a low-noise, fully integrated single-coil fan driver manufactured by Melexis Technologies NV. Designed for consumer applications in IT, home appliances, and industrial sectors, it supports supply voltages ranging from 3.2V to 32V. The device features an SOT-23-6 surface-mount package and delivers a maximum output current of 660mA. It integrates a high-sensitivity Hall effect sensor and includes built-in power clamping capabilities. The component is optimized for fans, blowers, or pumps with power ratings up to 15W.
Feature Summary
- Fully integrated single-coil fan driver with built-in high-sensitivity Hall effect sensor
- Integrated power clamping functionality for protection against back EMF
- Adaptive commutation control for low acoustic noise and high efficiency
- Supports both open-loop and closed-loop speed control modes
Applications
- Fan motor drivers for IT equipment
- Blower control in home appliances
- Pump drivers in industrial systems
Procurement Notes
Verify the specific suffix BAB against official Melexis documentation to confirm exact electrical characteristics and pinout compatibility. Check component status as some variants may be marked not recommended for new designs. Ensure supply chain sources provide valid RoHS compliance data and moisture sensitivity level information before integration into production schedules.
Selection Notes
Select this model for applications requiring compact SOT-23-6 packaging and integrated magnetic sensing. It is suitable for 5V, 12V, and 24V systems where low noise and efficient commutation are critical. Consider the 660mA current limit when sizing for loads exceeding 15W. Verify that the integrated power clamping voltage matches the system's transient requirements without external TVS diodes.
Part Context
This part belongs to the MLX90411 family of intelligent fan drivers from Melexis. The KZE suffix indicates a straight-lead SOT-23-6 package variant within the consumer-grade segment. It complements other variants like the LLD (UTDFN) and automotive-grade versions, offering a balance of performance and form factor for space-constrained consumer electronics.
Replacement Considerations
Direct substitutes include other MLX90411 variants with compatible packages, such as MLX90411KZE-BAA-046-RE. Cross-model replacement requires verification of current limits and clamping voltages. Automotive-grade equivalents like MLX90411LZE require AEC-Q100 certification checks.
