Product details
Overview
MLX90372GVS-ACE-301-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT output with SAE J2716 APR2016 compliance, operates from -40°C to +160°C, features ISO26262 ASIL-C safety certification, and uses the PCB-less DMP-4 package (Pinout-B) with built-in capacitors for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90372GVS-ACE-301-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, pin-level design meaning, real-world application cards, and two validated alternative parts for angular/linear position sensing in high-temperature automotive systems.
Technical Context
The MLX90372GVS-ACE-301-RE 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 contact. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics-up to 32 points-and configurable SENT frame structure with error codes and user-defined values.
This variant uses DMP-4 Pinout-B (VSS/VDD/OUT/Input), where Input serves as NTC or analog/digital gateway, and operates in SENT 3µs mode with capacitor configuration #2. It is qualified to AEC-Q100 and certified as ISO26262 ASIL-C Safety Element out of Context (SEooC), with fail-safe state duration of 9.8–34.6 ms after digital single-event faults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | SENT or PWM output signal - Drives ECU input directly; supports push-pull or open-drain modes per configuration. |
| 2 | VSS | Analog/digital ground reference - Shared return path for supply and signal; requires low-impedance PCB connection. |
| 3 | VDD | Main power supply input - Accepts regulated 4.5–5.5 V or battery 6–18 V; internal regulator generates 3.3 V analog rail. |
| 4 | Input | NTC or analog/digital gateway - Enables temperature compensation or auxiliary signal injection without external circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous Bx/By/Bz measurement enables true 3D magnetic field decoding for absolute angle or linear position without mechanical stops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-ACE-300-RE | Same DMP-4 Pinout-B package and SENT/PWM capability, but configured for standard legacy mode without enhanced stray-field immunity tuning. | Used where magnet topology is well-controlled and external EMI is minimal; lacks -301's optimized stray-field rejection for high-noise zones. | Select when cost sensitivity outweighs need for highest noise immunity in proximity to high-current actuators. |
| MLX90371GVS-ABD-301-RE | Predecessor generation with identical DMP-4 Pinout-B and -301 option code, but lacks ISO26262 ASIL-C SEooC certification and advanced SENT diagnostics. | Valid for legacy designs where functional safety decomposition is not required; no support for 32-point PWL or Secure Sensor format. | Choose only for backward-compatible replacements where ASIL-C evidence and enhanced diagnostics are not mandated. |
Compared with MLX90372GVS-ACE-301-RE, the -300 variant offers identical form-factor and protocol support but reduced stray-field resilience, while the MLX90371 lacks ASIL-C safety qualification and modern SENT features-making the -301 optimal for new ASIL-B/C system designs requiring robustness and diagnostics.

Yes, the MLX90372GVS-ACE-301-RE supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selectable via end-user programming. SENT is the default and recommended mode for diagnostic-rich applications, while PWM provides deterministic timing for legacy ECU interfaces. Output mode selection does not require hardware changes-only reprogramming of the device's NVRAM.
What is the function of the Input pin on the MLX90372GVS-ACE-301-RE DMP-4 Pinout-B package?
On the MLX90372GVS-ACE-301-RE DMP-4 Pinout-B package, Pin 4 (Input) functions as an NTC thermistor interface or analog/digital gateway. It enables direct temperature compensation of magnetic measurements or injection of auxiliary signals (e.g., switch status or analog voltage), eliminating external signal conditioning circuitry and reducing system BOM count.
Is the MLX90372GVS-ACE-301-RE certified for functional safety applications?
Yes, the MLX90372GVS-ACE-301-RE is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC). It includes documented safety mechanisms-including watchdog timers, memory ECC, and diagnostic cycles-and is qualified to AEC-Q100. This enables its use as a foundational safety component in ASIL-B or ASIL-C systems, with proper integration into the overall safety architecture.
What package type and pin configuration does the MLX90372GVS-ACE-301-RE use?
The MLX90372GVS-ACE-301-RE uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input. This PCB-less package integrates decoupling capacitors and is designed for direct mounting onto flexible substrates or sensor housings, minimizing footprint and assembly steps.
