MLX91220KDC-ABR-020-TU

Current Sensors Overview

The MLX91220KDC-ABR-020-TU is a board-mount current sensor from Melexis, utilizing Hall effect technology for bidirectional AC/DC measurement. It features a sensitivity of 100mV/A and operates within a frequency range of DC to 300kHz. The device supports a supply voltage of 4.5V to 5.5V with a maximum supply current of 26mA. It offers a response time of 2µs and maintains linearity accuracy of ±0.6%. The component is housed in an 8-SOIC package (3.90mm width) and functions across an operating temperature range of -40°C to 125°C.

Current Sensors Feature Summary

• Integrates dual on-chip overcurrent detection outputs to reduce reliance on external comparators
• Factory calibrated for plug-and-play operation without requiring end-of-line calibration
• Employs differential sensing via two Hall plates to minimize external magnetic interference

Current Sensors Applications

• Automotive onboard chargers (OBC)
• DC-DC converter high-side monitoring
• Industrial motor control systems

Current Sensors Procurement Notes

Verify the specific suffix TU indicates tube packaging when sourcing. Confirm AEC-Q100 qualification status for automotive applications. Ensure compatibility with 5V supply rails and check isolation voltage ratings against system requirements. Validate pinout alignment for SOIC-8 footprint during PCB design integration.

Current Sensors Selection Notes

Choose this model for applications requiring isolated current sensing with integrated overcurrent protection. The fixed sensitivity of 100mV/A suits systems needing predictable analog output scaling. Consider the 300kHz bandwidth for high-frequency switching environments. The 8-SOIC package facilitates surface-mount assembly in compact designs.

Current Sensors Part Context

This part belongs to the MLX91220 series of integrated current sensors. It represents a second-generation in-package solution designed for robust reliability in power electronics. The series emphasizes low impedance and high bandwidth while maintaining electrical isolation between primary and secondary sides.

Current Sensors Replacement Considerations

MLX91220KDC-ABR-020-RE serves as a reel-packaged alternative with identical electrical characteristics. MLX91220KDC-ABR-020-SP offers single-unit spool packaging. Verify that substitution parts maintain the same 100mV/A sensitivity and SOIC-8 form factor.
