MLX91220KDC-ABR-020-RE

Current Sensors Overview

The MLX91220KDC-ABR-020-RE is a board-mount current sensor from Melexis, utilizing Hall effect technology for bidirectional AC/DC measurement. It features a 20A detection range with 100mV/A sensitivity and ±0.6% linearity. The device operates on a 4.5V to 5.5V supply, drawing a maximum of 26mA. It offers a 300kHz frequency response and a 2µs response time. Output is ratiometric voltage. It is housed in an 8-SOIC package (3.99mm width) and rated for -40°C to +125°C operation. It holds AEC-Q100 qualification.

Current Sensors Feature Summary

• Integrates differential Hall sensing elements within the package to minimize external magnetic interference.
• Factory calibrated for plug-and-power deployment without requiring end-of-line calibration.
• Supports both ratiometric mode for supply-dependent applications and fixed output modes.

Current Sensors Applications

• On-board chargers (OBC)
• DC-DC converter high-side monitoring
• Automotive power management systems

Current Sensors Procurement Notes

Verify the specific suffix '020' confirms the 20A rating against project requirements. Ensure the SOIC-8 package dimensions align with PCB footprint constraints. Confirm AEC-Q100 automotive qualification status matches system reliability standards. Check moisture sensitivity level (MSL 3) handling procedures during assembly.

Current Sensors Selection Notes

Select this component for applications requiring isolated current sensing up to 20A with high bandwidth. The ratiometric output simplifies interface with varying supply voltages. Consider the 2µs response time for fast transient detection needs. Verify thermal performance within the specified -40°C to +125°C ambient range.

Current Sensors Part Context

Part of the MLX91220 series, designed for robust current sensing in electric vehicle and industrial environments. Uses proprietary IMC-Hall technology for high reliability. Differentiated by its integrated sense conductor and high voltage isolation capabilities within a compact surface-mount package.

Current Sensors Replacement Considerations

MLX91220KDC-ABR-025-RE: Offers 25A rating instead of 20A. MLX91221KDC-ABR-020-RE: Operates on 3.3V supply instead of 5V. Verify pinout compatibility and sensitivity adjustments when substituting.
