MLX91217LVA-ACA-002-CR

Current Sensors Overview

The MLX91217LVA-ACA-002-CR is a high-speed IMC-Hall current sensor IC designed for inverter and converter applications. It features a 400 kHz bandwidth with a 2 microsecond response time, supporting current measurement ranges from 1A to 2000A. The device offers flexible 3.3V or 5V power supply options and includes dual overcurrent detection (OCD) capabilities. Factory calibrated for offset, sensitivity, filtering, and internal OCD thresholds, it utilizes IMC-Hall technology with a U-shaped shield for interference resistance.

Current Sensors Feature Summary

• Dual overcurrent detection functionality simplifies module design by reducing the need for external comparators
• Flexible power supply voltage supports both 3.3V and 5V operation for broader system integration
• IMC-Hall technology provides high signal-to-noise ratio and robustness against external magnetic interference

Current Sensors Applications

• Motor control systems requiring fast response times
• Inverter and converter topologies
• High-bandwidth power electronics applications

Current Sensors Procurement Notes

Verify the specific suffix codes against official Melexis documentation to ensure correct calibration settings and packaging configuration. Confirm that the selected variant matches the required current range and output type for your application. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Current Sensors Selection Notes

Select this component when high bandwidth and rapid transient response are critical for power conversion efficiency. The dual OCD feature allows for simplified protection circuitry compared to standard sensors. Ensure the mechanical assembly accommodates the U-shaped shield for optimal magnetic shielding performance in high-vibration environments.

Current Sensors Part Context

This model belongs to the second-generation high-speed current sensor series from Melexis. It builds upon previous generations by integrating advanced diagnostic features and higher bandwidth capabilities. The IMC-Hall technology differentiates it from conventional Hall sensors by offering superior immunity to stray magnetic fields common in dense power modules.

Current Sensors Replacement Considerations

MLX91216: Offers similar IMC-Hall technology but with a 250 kHz bandwidth instead of 400 kHz. Suitable if lower bandwidth is acceptable. MLX91218: Provides comparable 400 kHz performance and dual OCD features; verify pinout and calibration compatibility before substitution.
