Product details
Overview
MLX90372GVS-ACE-203-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT or PWM output, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, AEC-Q100 qualification, and supports programmable transfer characteristics (up to 32-point PWL) in a PCB-less DMP-4 package. It enables non-contacting throttle and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90372GVS-ACE-203-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional context, DMP-4 pin mapping, SENT/PWM timing constraints, stray-field immune operation mode (-203), and direct alternatives for angular/linear position sensing in high-temperature automotive environments.
Technical Context
The MLX90372GVS-ACE-203-SP implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling robust 360° absolute angle or linear displacement decoding without mechanical wear. Its on-chip DSP performs real-time signal conditioning, filtering, and piecewise-linear (PWL) transfer function interpolation using up to 32 user-defined points.
It supports two output protocols: SAE J2716 APR2016 SENT (3 µs tick, Fast or Normal mode) and PWM with configurable duty cycle resolution. The -203 option code configures it for Linear Position Strayfield Immune mode, optimized for low-sensitivity magnetic circuits with enhanced immunity to external stray fields.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-ABF-203-SP | Single-die version with identical DMP-4 Pinout-B, same -203 stray-field immune linear mode, but lacks ASIL-C certification and SENT protocol support. | Targeted at cost-sensitive industrial linear position applications where functional safety and automotive diagnostics are not required. | Select when ASIL-C and SENT are unnecessary; lower BOM cost but no safety case documentation. |
| AMS AS5055A-BQFT | 360° rotary-only Hall encoder with SPI interface, ±0.2° accuracy, no stray-field immunity or linear mode; requires external MCU for processing. | Used in non-automotive rotary encoders (e.g., robotics joints), lacking integrated signal processing and automotive qualification. | Choose only for pure rotary applications with SPI infrastructure; no drop-in replacement due to different interface, package, and magnetic architecture. |
Compared with MLX90372GVS-ACE-203-SP, the MLX90371 alternative omits safety and SENT capabilities but matches pinout and linear stray-field operation, while the AS5055A requires full redesign for interface, packaging, and magnetic circuit - making MLX90372GVS-ACE-203-SP the sole qualified solution for ASIL-C linear position sensing in DMP-4 form factor.

FAQ
What output protocols does the MLX90372GVS-ACE-203-SP support?
The MLX90372GVS-ACE-203-SP supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selectable via end-user programming. SENT operates in Normal (3 µs tick) or Fast (1.5 µs tick) mode with secure sensor format including CRC and status bits; PWM provides deterministic timing with configurable duty cycle resolution. Both outputs are driven from the same OUT terminal in the DMP-4 Pinout-B configuration.
What does the "-203" option code signify for MLX90372GVS-ACE-203-SP?
For MLX90372GVS-ACE-203-SP, the "-203" option code specifies Linear Position Strayfield Immune mode - a factory-configured magnetic front-end setting that optimizes sensitivity and noise rejection for linear displacement applications in environments with strong orthogonal magnetic interference. It is distinct from -100 (rotary stray-field) and -300 (legacy) modes and requires compatible magnet geometry and calibration.
Is MLX90372GVS-ACE-203-SP qualified for automotive use?
Yes, MLX90372GVS-ACE-203-SP is AEC-Q100 qualified for Grade 0 (-40°C to +160°C) and certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC). Its qualification covers the full DMP-4 package, including thermal performance, EMC behavior, and functional safety mechanisms such as dual watchdogs, memory ECC, and diagnostic cycle timers - all validated per automotive requirements.
How is the MLX90372GVS-ACE-203-SP powered in battery-connected applications?
The MLX90372GVS-ACE-203-SP supports dual-supply operation: it accepts either a regulated 4.5–5.5 V rail or a direct 6–18 V battery connection. Internal circuitry automatically detects the supply mode and configures overvoltage protection thresholds accordingly (e.g., 7.35 V PTC entry for 5 V mode vs. 23.0 V for battery mode). This eliminates external voltage regulation in 12 V automotive systems while maintaining robust start-up down to 3.6 V.
What package type and mounting method does MLX90372GVS-ACE-203-SP use?
MLX90372GVS-ACE-203-SP uses the DMP-4 (Dual Mould Package) with Pinout-B configuration - a PCB-less, 4-terminal surface-mount package designed for direct wire bonding or spring-contact interfacing. It has no solder pads or leads; terminals are molded into thermoset epoxy and rated for high-vibration environments. Mounting requires mechanical retention (e.g., adhesive, clip, or housing press-fit), not reflow soldering.
