Overview
The MLX90412KLW-BAC-025-RE is a single-coil fan driver from Melexis, designed for consumer applications. It integrates a high-sensitivity Hall effect sensor and supports open-loop control with a maximum current of 1.5A at 20V. The device features adaptive commutation for low acoustic noise and high efficiency across the speed range. It utilizes a DFN-WF-10 surface-mount package.
Feature Summary
- Integrates a high-sensitivity Hall effect sensor for precise rotor position detection
- Adaptive commutation technology ensures low acoustic noise and high efficiency
- Supports open-loop speed control without external feedback components
Applications
- Consumer electronics cooling fans
- Household appliance blowers
- Small pump drives
Procurement Notes
Verify the specific suffix BAC against official documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status and humidity sensitivity handling requirements before assembly. Check for export restrictions or additional documentation needs for your region.
Selection Notes
Select this component for cost-sensitive single-coil fan applications requiring integrated sensing. Ensure the load current does not exceed 1.5A and the supply voltage aligns with the 20V rating. Consider the DFN-WF-10 package size constraints during PCB layout.
Part Context
This part belongs to the MLX90412 series of smart fan drivers. It is positioned as a consumer-grade solution, distinct from automotive-grade variants which may carry different reliability standards or extended temperature ranges.
Replacement Considerations
Check for direct substitutes within the MLX90411 or MLX90412 families. Verify compatibility of the DFN-WF-10 footprint and electrical parameters such as current limit and supply voltage.
