Technical Context
The MLX90373KVS-ABA-100-RE implements Triaxis® Hall sensing architecture with integrated IMC to resolve all three magnetic field components (BX, BY, BZ), enabling robust absolute angle decoding from magnet motion without mechanical contact. Its on-chip DSP performs real-time signal processing including multi-point linearization (up to 32 points), configurable filtering, and diagnostics.
This variant uses the -100 option code, configuring it exclusively for Rotary Stray-Field Immune mode with 4-pole magnet support and magnetic gradient sensitivity of 4.1–10 mT/mm. It communicates via 2-wire PSI5 over supply lines with 300–500 µs cycle time, 850 µs latency, and 1480–2125 µs worst-case step response - all validated under AEC-Q100 stress conditions.

FAQ
What is the primary magnetic sensing mode configured in MLX90373KVS-ABA-100-RE?
The MLX90373KVS-ABA-100-RE is factory-configured for Rotary Stray-Field Immune mode (option code -100), using magnetic gradient ∆BXY/∆XY as its primary signal. This enables accurate 0–360° absolute angle measurement while rejecting uniform external magnetic interference up to 5 mT, as validated per ISO 11452-8. The device does not operate in legacy linear or standard angular modes unless reprogrammed.
Does MLX90373KVS-ABA-100-RE require an external microcontroller to process position data?
No, the MLX90373KVS-ABA-100-RE integrates full signal conditioning, digital processing, and PSI5 output generation on-die. It outputs calibrated 12-bit position data directly via its 2-wire PSI5 interface - no external MCU or ADC is needed for basic operation. Configuration and calibration are performed once via PTC, after which the device operates autonomously.
What package type and lead configuration does MLX90373KVS-ABA-100-RE use?
The MLX90373KVS-ABA-100-RE uses the DMP-4 (Dual Mold Package) with four terminals: two VSS (ground), one VDD (supply/PSI5 output), and one N.C. (no-connect, recommended grounded). It features straight leads (STD1) per ordering code -100, is PCB-less, and designed for direct surface mounting on flex or rigid substrates without a carrier board.
How does MLX90373KVS-ABA-100-RE meet automotive functional safety requirements?
The MLX90373KVS-ABA-100-RE is certified as a Safety Element out of Context (SEooC) per ISO 26262 with ASIL-C capability. It incorporates dual independent watchdogs (IWD and AWD), CRC-protected NVRAM, ECC on critical memory, and diagnostic coverage for sensor front-end, DSP, and communication layers - all documented in Melexis' official safety manual for integration into ASIL-B or ASIL-C systems.
Can MLX90373KVS-ABA-100-RE be used in linear position sensing applications?
No - the MLX90373KVS-ABA-100-RE is specifically configured for Rotary Stray-Field Immune operation and is not intended for linear position sensing. Linear or combined linear/angular applications require option codes -300, -303, or -308 (e.g., MLX90373KVS-ABA-300-RE). Using -100 in linear configurations results in degraded accuracy and invalidates stray-field immunity claims.
