Product details
Overview
MLX90374GVS-ABB-300-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers dual-output SENT + programmable switch or dual PWM signals, supports -40°C to +160°C operation, achieves ±0.3° angular accuracy in legacy mode, and integrates ISO26262 ASIL-C safety mechanisms. It is used in throttle, pedal, and steering wheel position sensing where stray-field immunity and functional safety are critical.
For engineers reviewing the MLX90374GVS-ABB-300-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed dual-output timing behavior (SENT + switch), validated AEC-Q100 qualification, exact pin functions per official SOIC-8/DMP-4 definitions, and real-world automotive sensor use cases with design-meaning parameters.
Technical Context
The MLX90374GVS-ABB-300-RE uses Triaxis® Hall technology to measure all three magnetic field components (Bx, By, Bz), enabling robust absolute angle decoding from 0° to 360° or linear displacement without contact. Its on-chip DSP performs real-time signal conditioning, piecewise linear (PWL) transfer function correction (up to 32 points), and configurable diagnostics including intelligent and absolute watchdogs.
This variant operates in Legacy/Standard mode (-300 option code), supporting both SENT (SAE J2716 APR2016 compliant) and dual PWM output configurations. It features internal regulated VDEC (3.3 V ±0.1 V), programmable measurement range, and built-in surge current protection (40 mA peak), with startup time of 6.99 ms for SENT single-angle frames and latency as low as 1.73 ms under FIR11 filtering.

FAQ
What is the primary magnetic sensing architecture used in the MLX90374GVS-ABB-300-RE?
The MLX90374GVS-ABB-300-RE employs Triaxis® Hall technology, which simultaneously measures all three orthogonal components (Bx, By, Bz) of the applied magnetic flux density. This enables accurate decoding of absolute rotary or linear position using a single die, without requiring external magnetic concentrators or multi-axis sensor fusion. The architecture is intrinsic to the MLX90374GVS-ABB-300-RE's ability to operate in legacy mode (-300) with ±0.3° angular accuracy.
Does the MLX90374GVS-ABB-300-RE support SENT protocol, and what version is implemented?
Yes, the MLX90374GVS-ABB-300-RE supports Single Edge Nibble Transmission (SENT) per SAE J2716 APR2016. It delivers enhanced serial messages containing 12-bit position data, CRC checksums, diagnostic flags, and user-defined values. Frame timing is configurable for 1.5 µs (Fast), 3 µs (Normal), or 6 µs (Slow) tick rates, with synchronous or asynchronous acquisition modes - all fully supported in the MLX90374GVS-ABB-300-RE's -300 option configuration.
What is the difference between the ABB and ABC revisions in the MLX90374GVS-ABB-300-RE ordering code?
The ABB revision in MLX90374GVS-ABB-300-RE is not recommended for new designs and lacks certain safety features present in the ABC revision, including cold safe startup (TSafeStup = 11.2 ms), enhanced diagnostic cycle timing, and updated failure mode coverage per ISO26262. While both share identical pinout, package (DMP-4), and core functionality, the ABC revision provides stronger ASIL-C evidence and is required for new automotive programs - the MLX90374GVS-ABB-300-RE remains in production for legacy replacements only.
Can the MLX90374GVS-ABB-300-RE operate directly from a 12 V automotive battery?
Yes, the MLX90374GVS-ABB-300-RE supports battery-supplied operation from 6 V to 18 V, with internal regulation generating stable 3.3 V (VDEC) and 1.85 V (VDDD) rails. It includes overvoltage detection thresholds at 7.35 V (5 V mode) and 23.0 V (battery mode), plus surge current capability up to 40 mA. This allows direct connection to unregulated 12 V lines in automotive ECUs - a key design feature of the MLX90374GVS-ABB-300-RE's power architecture.
What package type does the MLX90374GVS-ABB-300-RE use, and what are its key layout advantages?
The MLX90374GVS-ABB-300-RE uses the DMP-4 (Dual Mold Package), a PCB-less 4-terminal surface-mount solution with integrated 10 nF decoupling capacitors (C1, C4). This eliminates external bypass components, reduces PCB area by >60% versus SOIC-8, and improves EMC performance through minimized loop inductance. The DMP-4 footprint and terminal layout are standardized per Melexis specification 17.6 - a defining physical characteristic of the MLX90374GVS-ABB-300-RE.
