Current Sensors Procurement Notes

Verify the specific suffix 'ACX' corresponds to the required high-field sensitivity (20mV/mT) for your application's current range. Confirm the 'RE' suffix indicates reel packaging if automated assembly is required. Ensure the SOIC8 package dimensions align with your PCB footprint. Check for RoHS compliance status and AEC-Q100 Grade 0 qualification requirements for automotive integration.

Current Sensors Selection Notes

Select this model when high magnetic field strength is necessary, as the ACX variant is designed for extreme fields suitable for currents up to 2000A. Consider the 250 kHz bandwidth and 2μs response time for high-speed switching applications. Evaluate the need for programmable features to tailor sensitivity and filtering to specific noise environments. Compare against ACH or ACV variants if lower current ranges are sufficient.

Current Sensors Part Context

This component belongs to the MLX91216 series, representing the second generation of high-speed IMC-Hall current sensors. It is part of Melexis' portfolio aimed at providing robust, isolated current sensing solutions for demanding automotive and industrial environments.
