Product details
Overview
MLX90374GDC-ABC-200-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC designed for absolute linear position sensing in harsh environments. It delivers robust stray-field immune operation, dual PWM or SENT + programmable switch outputs, and meets AEC-Q100 Grade 0 (−40°C to +160°C) and ISO 26262 ASIL-C safety requirements. Used in automotive pedal and throttle position sensing where high reliability and EMC resilience are critical.
For engineers reviewing the MLX90374GDC-ABC-200-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOIC-8), confirmed linear stray-field immune configuration (-200 option code), dual-output timing specs, functional safety architecture, and validated alternative options for automotive position sensing designs.
Technical Context
The MLX90374GDC-ABC-200-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling precise decoding of magnet position without mechanical contact. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics with up to 32 points and configurable filtering (FIR11/FIR1111).
It operates in continuous asynchronous acquisition mode (TangleMeas = 528–588 µs) for PWM/SENT output, with SENT compliant to SAE J2716 APR2016 and dual PWM featuring redundant error reporting. The ABC revision includes cold-safe startup (TSafeStup = 11.2–12.4 ms) and enhanced diagnostics versus legacy ABB.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90375GDC-ABC-200-RE | Successor device with extended temperature range (−40°C to +175°C), improved INL (±0.15% FS), and faster SENT startup (≤5.2 ms) | Targeted for next-gen powertrain and transmission control where higher junction temp margin is required | Select MLX90375GDC-ABC-200-RE for new designs needing enhanced thermal headroom and tighter linearity |
| TAS5754MRTWR | TI Hall-effect linear position sensor with I²C interface, ±0.5% FS accuracy, and −40°C to +150°C rating; no SENT/PWM dual output or ASIL-C certification | Used in industrial automation where functional safety is not mandated and I²C bus integration is preferred | Choose TAS5754MRTWR only when I²C communication and lower cost outweigh need for automotive safety compliance and dual-output redundancy |
Compared with MLX90374GDC-ABC-200-RE, the MLX90375GDC-ABC-200-RE offers higher thermal resilience and precision but shares identical SOIC-8 pinout and programming interface; TAS5754MRTWR provides I²C flexibility but lacks ASIL-C support, SENT compatibility, and stray-field immunity validation for linear position use cases.

FAQ
What is the primary magnetic sensing architecture used in the MLX90374GDC-ABC-200-RE?
The MLX90374GDC-ABC-200-RE employs Melexis' proprietary Triaxis® Hall technology, which simultaneously measures all three orthogonal components (Bx, By, Bz) of the applied magnetic flux density. This 3D capability enables accurate absolute position decoding for both linear and rotary motion without mechanical contact, and is fundamental to its stray-field immune performance in the -200 configuration.
Does the MLX90374GDC-ABC-200-RE support SENT protocol, and if so, which version?
Yes, the MLX90374GDC-ABC-200-RE supports SENT protocol compliant with SAE J2716 APR2016. It operates in both normal (3 µs tick time) and fast (1.5 µs tick time) modes, with configurable frame lengths and support for enhanced messages containing error codes and user-defined data. SENT operation is enabled via factory programming and user configuration of the SENT_SEL_SR_RISE/FALL parameter.
What does the "-200" option code signify for the MLX90374GDC-ABC-200-RE?
The "-200" option code identifies the MLX90374GDC-ABC-200-RE as configured for linear position sensing with stray-field immunity. This includes optimized magnetic front-end calibration, DSP filter settings, and factory-programmed transfer characteristics tailored to reject interference from external magnetic sources-critical for placement near motors, solenoids, or ignition systems in automotive applications.
Is the MLX90374GDC-ABC-200-RE pin-compatible with earlier revisions like ABB?
No, the MLX90374GDC-ABC-200-RE is not pin-compatible with ABB-revision devices. While both use the SOIC-8 package, the ABC revision introduces updated internal diagnostics, cold-safe startup, and enhanced SENT timing behavior that require corresponding firmware and system-level validation. Melexis explicitly states ABB is "not recommended for new designs" due to missing ABC features.
What safety certifications apply to the MLX90374GDC-ABC-200-RE?
The MLX90374GDC-ABC-200-RE is certified to AEC-Q100 Grade 0 (−40°C to +160°C) and qualified as an ISO 26262 ASIL-C Safety Element out of Context (SEooC). It incorporates hardware-level safety mechanisms including dual watchdogs (IWD and AWD), memory ECC, diagnostic cycle timers, and a safe startup sequence-enabling integration into ASIL-B or ASIL-C automotive systems with appropriate system-level decomposition.
