MLX90411LZE-BAO-043-RE

Overview

The MLX90411LZE-BAO-043-RE is an automotive-grade single-coil fan driver from Melexis, designed for low-noise operation in demanding environments. It features a 40V integrated power clamp to handle load dump conditions and supports supply voltages from 3.2V to 32V. The device provides a current limit of 330mA and includes adaptive commutation control for efficiency and noise reduction. Packaged in a compact SOT-23-6L surface-mount format, it integrates a high-sensitivity Hall sensor and offers programmable open-loop PWM speed control with adaptive low-noise frequency generation outputs.

Feature Summary

Integrated 40V power clamp for robust protection against voltage transients
Adaptive commutation technology ensures low acoustic noise and high efficiency
On-chip Hall sensor enables precise rotor position detection without external components
Programmable I2C interface allows flexible configuration via onboard EEPROM

Applications

Automotive LED headlight cooling fans
Vehicle seat ventilation systems
Sensor cooling applications
Multimedia GPU thermal management

Procurement Notes

Verify the specific suffix 'BAO' against official Melexis documentation to confirm exact electrical parameters and pinout compatibility. Check AEC-Q100 qualification status and RoHS compliance details prior to integration. Ensure design-in reviews account for the 330mA current limit and 40V clamp specifications to match application requirements accurately.

Selection Notes

Select this component for automotive thermal management where low noise and high reliability are critical. The 40V clamp makes it suitable for direct 12V battery connections with load dump protection. Consider the SOT-23-6L package size for space-constrained PCB layouts. Verify that the 330mA output current meets the motor's operational needs.

Part Context

This part belongs to the MLX90411 series of intelligent fan drivers. It represents the automotive-grade variant (indicated by LZE) optimized for harsh environments. The series is known for integrating sensing and driving capabilities into a single chip, reducing bill-of-materials complexity compared to discrete solutions.
