Overview
The MLX90411KZE-BZB-046-RE is a low-noise, fully integrated single-coil fan driver manufactured by Melexis Technologies NV. It operates within a supply voltage range of 3.2V to 32V and delivers an output current up to 1A. The device utilizes a SOT-23-6 surface-mount package and accepts PWM interface signals for control. Designed for consumer applications, it integrates high-sensitivity Hall effect sensors and power clamping capabilities.
Feature Summary
- Fully integrated single-coil fan driver with built-in high-sensitivity Hall effect sensor
- Integrated power clamp protection for transient voltage suppression
- Adaptive commutation control for optimized efficiency and acoustic noise reduction
- Configurable open-loop and closed-loop speed control via I2C programming
Applications
- Consumer electronics cooling fans
- Household appliance blowers
- Industrial pump drives
- Information technology thermal management systems
Procurement Notes
Verify the specific suffix BZB against official Melexis documentation to confirm exact electrical parameters and pinout compatibility. Confirm RoHS3 compliance status and moisture sensitivity level prior to integration. Check component obsolescence status as some variants may be restricted from new designs. Ensure ESD handling protocols are followed during assembly due to semiconductor sensitivity.
Selection Notes
Select this variant for applications requiring a compact SOT-23-6 footprint with integrated sensing and driving capabilities. The 40V clamp version suits higher voltage bus applications compared to 20V variants. Consider the programmable features for custom speed curves and diagnostic outputs. Evaluate thermal performance requirements relative to the maximum output current in the target enclosure environment.
Part Context
This component belongs to the MLX90411 series of intelligent fan drivers designed for cost-effective and space-constrained thermal solutions. The KZE suffix indicates a straight-pin SOT-23-6 package configuration suitable for standard surface mount assembly processes. The series supports various current limits and voltage ratings to accommodate diverse motor loads.
Replacement Considerations
Consult official Melexis substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully when considering generic equivalents.
