Overview
The MLX90411KZE-BAC-046-RE is a low-noise, integrated single-coil fan driver manufactured by Melexis Technologies NV. It operates within a supply voltage range of 3.2V to 32V and supports a maximum output current of 660mA, with peak capabilities up to 1A. The device features an integrated 40V power clamp for transient protection and utilizes a SOT-23-6 surface-mount package. Designed for open-loop speed control via PWM input, it incorporates adaptive commutation for efficiency and noise reduction.
Feature Summary
- Integrated high-sensitivity Hall effect sensor for precise rotor position detection
- Adaptive commutation control optimizing efficiency across the full speed range
- Built-in 40V power clamp eliminating external transient voltage suppression requirements
- Configurable PWM input with selectable pull-up or pull-down resistors
Applications
- Single-coil fan motors in consumer electronics
- Blower motors in home appliances
- Small pump drives in industrial equipment
- Thermal management systems in IT hardware
Procurement Notes
Verify component authenticity through authorized Melexis distributors. Confirm RoHS3 compliance and MSL level 3 handling requirements during storage. Check for NRND status implications regarding long-term availability. Ensure PCB layout adheres to thermal dissipation guidelines for the SOT-23-6 package to maintain performance reliability under continuous operation.
Selection Notes
Select this variant for applications requiring 40V transient tolerance and 660mA current limits. The SOT-23-6 package suits space-constrained designs. Verify compatibility with existing PWM control signals and FG output configurations. Consider alternative current ratings if load demands exceed specified limits. Ensure system voltage remains within the 3.2V to 32V operational window.
Part Context
Part of the MLX90411 family of integrated fan drivers. Distinguished by its specific electrical ratings and packaging configuration. Designed as a drop-in replacement for discrete motor drive solutions. Offers simplified design implementation through integrated sensing and power stages.
Replacement Considerations
MLX90411KZE-BAA-046-RE offers identical electrical specifications and pinout compatibility. Both variants share the same functional architecture and package dimensions. Verify exact ordering suffix alignment to ensure mechanical and electrical interchangeability in existing assemblies.
