MLX90411KZE-BAA-023-RE

Overview

The MLX90411KZE-BAA-023-RE is a single-coil fan driver from Melexis, designed for consumer applications. It features an integrated high-sensitivity Hall effect sensor and supports open-loop speed control. The device operates with a supply voltage range of 3.2V to 32V and provides a current limit of 330mA. It includes a 20V power clamp for protection against back EMF. The component is housed in a SOT-23-6 package and is marked as Not Recommended for New Designs (NRND).

Feature Summary

Integrated single-coil fan driver with built-in Hall effect sensor
Supports open-loop speed control with programmable dynamic PI settings
Includes 20V integrated power clamp for back EMF protection
Features FG/RD diagnostic output options

Applications

Consumer electronics cooling fans
Household appliance blowers
Industrial pump applications

Procurement Notes

Verify the NRND status before implementation, as this part is not recommended for new designs. Confirm that the 330mA current limit and 20V clamp specifications align with the specific load requirements. Ensure the SOT-23-6 package footprint matches the PCB layout. Check for alternative automotive-grade versions if higher reliability or different packaging is required.

Selection Notes

Select this component for low-noise, cost-effective single-coil fan control in consumer devices. The 20V clamp is suitable for 5V and 12V systems without external TVS diodes. Consider the MLX90411LLD variant if AEC-Q100 automotive qualification or a smaller UTDFN package is needed. Verify that the open-loop control meets the application's precision requirements.

Part Context

This part belongs to the MLX90411 family of intelligent fan drivers. It is specifically the consumer-grade version (indicated by 'K' in the suffix) utilizing a SOT-23-6 package. Unlike the automotive L-series, it lacks AEC-Q100 certification but offers similar core driving capabilities optimized for general-purpose thermal management.
