Product details
Overview
MLX90372GVS-ACC-303-RE 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, and supports programmable transfer characteristics (up to 32-point PWL) in a PCB-less DMP-4 package with Pinout-B configuration.
For engineers reviewing the MLX90372GVS-ACC-303-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin definitions, real-world automotive use cases, and confirmed alternative options for throttle, pedal, steering, and ride-height sensing designs.
Technical Context
The MLX90372GVS-ACC-303-RE implements Triaxis® Hall sensing to resolve all three magnetic field components (Bx, By, Bz), enabling robust absolute angle or linear displacement measurement without mechanical contact. Its on-chip DSP performs real-time signal conditioning, filtering, and piecewise-linear interpolation using up to 32 user-defined points.
It supports two timing modes: continuous asynchronous acquisition (588 µs typical measurement period) for PWM and SENT-without-pause, and synchronous acquisition aligned to SENT frame boundaries (960 µs typical frame period at 3 µs tick). Output is configurable as SENT per SAE J2716 APR2016 or PWM with programmable duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments including engine bay and transmission mounting. |
| Supply Voltage | 4.5–5.5 V (regulated mode) or 6–18 V (battery mode) - supports direct battery connection with integrated over/under-voltage protection. |
| Output Interface | Configurable SENT (SAE J2716 APR2016) or PWM - SENT includes error codes and user-defined data; PWM offers deterministic timing for ECU synchronization. |
| Accuracy | ±0.5° typical angular error in legacy (-300) mode - enables high-fidelity throttle and steering wheel position feedback in ASIL-C systems. |
| Transfer Function | Programmable 4/8/16/32-point PWL - allows precise linearization of non-ideal magnet trajectories without external calibration hardware. |
| Safety Certification | ISO26262 ASIL-C Safety Element out of Context - provides documented safety mechanisms (watchdog, memory ECC, diagnostics) for integration into ASIL-D systems. |
| Package | DMP-4 with Pinout-B - PCB-less dual-mold package with 4 terminals (OUT/VSS/VDD/Input), optimized for compact, high-reliability sensor assemblies. |
Pinout & Package
DMP-4 package (PCB-less dual mold) with Pinout-B configuration: compact 4-terminal surface-mount module with integrated capacitors, designed for direct magnet coupling and minimal footprint in space-constrained automotive sensors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | SENT or PWM output signal - push-pull or open-drain capable; supports pull-up to 5–18 V; short-circuit protected (25 mA typical limit). |
| 2 | VSS | Digital/analog ground reference - shared ground terminal; must be connected to low-impedance system ground for EMC and accuracy. |
| 3 | VDD | Main supply input - accepts 4.5–18 V; internal regulator generates 3.3 V analog rail (VDEC) and 1.85 V digital rail (VDDD). |
| 4 | Input | NTC or analog/digital gateway input - used for temperature compensation (e.g., NTC biasing) or auxiliary sensor interface in Pinout-B configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Front End | Simultaneous Bx/By/Bz sensing enables true 3D magnetic field decoding - eliminates need for external concentrators or multi-die solutions in rotary/linear applications. |
| Stray-Field Immunity | Validated operation under ±1 T external interference - critical for reliable pedal and throttle sensing near motors, solenoids, or high-current wiring. |
| Secure SENT Protocol | 48-bit ID + CRC + diagnostic flags in every frame - enables traceability, fault detection, and secure communication in safety-critical ECUs. |
| On-Chip DSP Processing | Real-time PWL interpolation, FIR filtering, and temperature compensation - removes requirement for host MCU computational overhead or external calibration tables. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-ACE-303-RE | Same DMP-4 Pinout-B package and -303 functionality, but ACE revision replaces ACC - includes enhanced ESD robustness and updated factory calibration. | No change in target applications; identical angular/linear sensing capability and SENT/PWM configuration. | Select ACE-303 for new designs; ACC-303 remains production-supported but not recommended for new projects per Melexis documentation. |
| MLX90371GVS-ACC-303-RE | Single-die predecessor with same DMP-4 Pinout-B, but lacks ASIL-C safety mechanisms, SENT protocol enhancements, and advanced diagnostics. | Suitable only for non-safety-critical industrial or consumer applications - not qualified for ASIL-B/C automotive functions. | Use only where functional safety certification is unnecessary; MLX90372GVS-ACC-303-RE provides mandatory safety features for OEM powertrain and chassis systems. |
Compared with MLX90372GVS-ACE-303-RE, the ACC-303 variant retains full electrical and functional compatibility but omits later silicon-level improvements; versus MLX90371GVS-ACC-303-RE, the MLX90372GVS-ACC-303-RE adds ASIL-C compliance, SENT v2.0 support, and expanded programmability - making it the only choice for current-generation automotive safety architectures.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACC-303-RE?
The MLX90372GVS-ACC-303-RE uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: four terminals labeled OUT, VSS, VDD, and Input. This PCB-less package integrates decoupling capacitance and supports direct magnet coupling. Pinout-B enables use of the Input terminal for NTC biasing or auxiliary analog/digital signals - a key differentiator from Pinout-A.
Does MLX90372GVS-ACC-303-RE support both SENT and PWM outputs?
Yes, MLX90372GVS-ACC-303-RE supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selectable via end-user programming. SENT provides 48-bit ID, CRC, and diagnostic flags per frame; PWM offers fixed-frequency, programmable duty cycle output with sub-microsecond timing precision - both are fully supported in the DMP-4 Pinout-B configuration.
Is MLX90372GVS-ACC-303-RE certified for automotive safety standards?
Yes, MLX90372GVS-ACC-303-RE is ISO26262 ASIL-C compliant as a Safety Element out of Context (SEooC) and AEC-Q100 Grade 0 qualified. It includes built-in safety mechanisms such as dual watchdog timers (IWD/AWD), memory ECC, and diagnostic cycle monitoring - all documented in the official Melexis safety manual for integration into ASIL-D systems.
What is the operating temperature range of MLX90372GVS-ACC-303-RE?
The MLX90372GVS-ACC-303-RE operates from -40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. This range is validated for continuous operation in engine compartments, transmission housings, and brake modules - with thermal performance data confirmed in Section 18.17 of the official datasheet.
Can MLX90372GVS-ACC-303-RE be programmed for custom transfer characteristics?
Yes, MLX90372GVS-ACC-303-RE supports user-programmable transfer characteristics using up to 32-point Piecewise Linear (PWL) interpolation. This is configured via Melexis' PTC software tool and stored in on-chip NVRAM. The feature enables precise linearization of magnet trajectories in applications like throttle bodies or ride-height linkages without host MCU intervention.
