MLX90411KZE-BPA-043-RE

Overview

The MLX90411KZE-BPA-043-RE is a fully integrated single-coil fan driver IC from Melexis, designed for 5V, 12V, 24V, and 32V applications. It features a 40V power clamp and supports output currents up to 1A. The device utilizes a SOT-23-6 surface-mount package and operates within a temperature range of -40°C to 150°C TJ. It integrates a high-sensitivity Hall effect sensor for commutation and offers adaptive control options for low acoustic noise or high efficiency. The component supports both open-loop and closed-loop speed control via PWM input.

Procurement Notes

Verify the specific suffix BPA confirms the 40V rating and SOT-23-6 package configuration against the official datasheet before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any export restrictions or additional documentation needed for international shipping. Ensure the component status is acceptable for your design lifecycle, as it may be marked as not recommended for new designs in some regions.

Selection Notes

Select this part when a compact solution for single-coil fans is required with integrated overvoltage protection. The 40V clamp eliminates the need for external TVS diodes in higher voltage systems. Consider the SOT-23-6 package for space-constrained PCB layouts. Evaluate the thermal performance at maximum current loads to ensure adequate heat dissipation within the operating temperature range.

Part Context

This component belongs to the MLX90411 series, which includes consumer-grade variants optimized for IT, home appliances, and industrial sectors. The series provides various current limits and voltage clamping options to suit different power requirements. The MLX90411 family is known for its low-noise operation and flexible configuration capabilities through onboard EEPROM.

Replacement Considerations

Consult the official Melexis documentation for direct pin-to-pin replacements or functional equivalents within the MLX90411 family. Verify that any substitute maintains the 40V clamp specification and SOT-23-6 footprint. Cross-reference electrical parameters such as output current and operating voltage to ensure compatibility.
