MLX90411LZE-BAA-043-RE

Overview

The MLX90411LZE-BAA-043-RE is an automotive-grade single-coil fan driver from Melexis, designed for low-noise operation in thermal management systems. It integrates a high-sensitivity Hall effect sensor and power stage within a compact SOT-23-6 package. The device supports a supply voltage range of 3.2V to 40V and features a current limit of 330mA. It includes integrated power clamping for transient protection and offers adaptive commutation options to minimize acoustic noise and maximize efficiency across the operating speed range.

Feature Summary

Integrated high-sensitivity Hall effect sensor for precise rotor position detection
Adaptive commutation control for optimized efficiency and minimal acoustic noise
Built-in power clamping circuitry for robust transient voltage protection
Configurable open-loop PWM speed control with flexible minimum point transfer curves

Applications

Automotive LED headlight cooling fans
Vehicle seat ventilation fans
Sensor cooling fans
Multimedia GPU cooling fans

Procurement Notes

Verify component authenticity through authorized Melexis distributors or direct channels. Confirm AEC-Q100 qualification status and RoHS compliance prior to integration. Ensure proper handling of moisture-sensitive devices according to specified reflow profiles. Validate that the specific suffix corresponds to the required voltage clamp and current limit parameters for the target application design.

Selection Notes

Select this variant for applications requiring a 330mA output current limit and 40V power clamping capability. The SOT-23-6 package is suitable for space-constrained PCB layouts. Consider alternative packages like UTDFN if smaller footprint is prioritized over pin configuration. Ensure the system operates within the specified -40°C to 150°C junction temperature range for automotive reliability.

Part Context

This component belongs to the MLX90411 family of single-coil fan drivers. It is specifically designated as the automotive-grade version (L-series) compared to consumer variants. The LZE suffix indicates the SOT-23-6 surface-mount package type. This series is engineered to replace discrete driver solutions by integrating sensing, control, and power stages into a single chip.
