Product details
Overview
MLX90372GVS-ACE-350-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT output per SAE J2716 APR2016, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance as a Safety Element out of Context, and uses the PCB-less DMP-4 package with Pinout-B configuration (VDD/VSS/OUT/Input). It enables non-contacting throttle, pedal, and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90372GVS-ACE-350-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional context, DMP-4 Pinout-B terminal mapping, SENT/PWM output mode selection, stray-field immune angular/linear measurement capability, and AEC-Q100 qualified design parameters for automotive sensor integration.
Technical Context
The MLX90372GVS-ACE-350-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, an analog-to-digital signal conditioner, and a DSP for real-time angle computation. Its DMP-4 package (Pinout-B) exposes VDD, VSS, OUT, and Input terminals - the latter configurable as NTC input or analog/digital gateway.
This variant uses ACE chip revision, supports SENT 3µs mode, and is configured for standard angular/linear position sensing (option code -350). It implements programmable piecewise linear (PWL) transfer characteristics (up to 32 points), robust stray-field immunity, and dual diagnostics (IWD/AWD) with fail-safe state duration of 9.8–34.6 ms depending on fault type.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments including transmission and engine control modules. |
| Supply Voltage | 4.5–5.5 V (regulated) or 6–18 V (battery) - supports direct battery connection with integrated over/under-voltage protection. |
| Output Protocol | SENT per SAE J2716 APR2016 or PWM - SENT frames include CRC, error codes, and user-defined values; PWM duty cycle encodes position. |
| Accuracy (Legacy Mode) | ±0.5° typical angular error - validated across full 0–360° range with calibrated magnet and optimized mechanical setup. |
| Supply Current | 8.0–10.5 mA (legacy mode) - enables low-power operation in always-on vehicle subsystems without thermal derating. |
| Magnetic Range | ±1 T maximum flux density - withstands strong stray fields common near motors, solenoids, and high-current conductors. |
| Safety Certification | ISO26262 ASIL-C SEooC - provides documented safety mechanisms (watchdogs, memory ECC, diagnostic cycles) for integration into ASIL-B/C systems. |
Pinout & Package
DMP-4 package (PCB-less dual mold), Pinout-B configuration, RoHS-compliant, STD3 2.00 mm trim & form (option code -350 → -3xx = STD3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | SENT or PWM output driver - push-pull capable; supports open-drain configuration with external pull-up up to 18 V. |
| 2 | VSS | Digital/analog ground reference - must be connected to low-impedance system ground for EMC and accuracy. |
| 3 | VDD | Main supply input - accepts regulated 4.5–5.5 V or unregulated 6–18 V battery input with internal regulation. |
| 4 | Input | NTC thermistor or analog/digital gateway input - enables temperature compensation or auxiliary sensor integration without external ADC. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx/By/Bz detection enables true absolute angle calculation from single moving magnet - eliminates need for multi-die or external interpolation. |
| Programmable PWL Transfer | Up to 32-point piecewise linear calibration allows precise correction of mechanical nonlinearity (e.g., gear backlash, cam profile distortion) in throttle or suspension linkages. |
| Stray-Field Immunity | Validated performance in >10 mT external stray fields - critical for placement near electric power steering motors or 48 V DC-DC converters. |
| Secure SENT Output | Embedded CRC, status flags, and diagnostic data in every frame - enables ECU-level validation of sensor health and position integrity in real time. |
| Dual Watchdog Architecture | Independent Intelligent Watchdog (IWD) and Absolute Watchdog (AWD) with 20 ms timeout - ensures deterministic fail-safe response to software lockup or clock failure. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|
Use Scenario: Real-time detection of accelerator pedal angle in gasoline and hybrid powertrains. IC Role / Device Role / Timing Role: Absolute angular position processor delivering SENT frames at 100 Hz with <10 µs jitter for closed-loop torque control.

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-ABD-350-SP | Single-die DMP-4, no ASIL-C certification, SENT-only output (no PWM), lower diagnostic coverage. | Limited to non-safety-critical applications like HVAC flap control or seat position where ASIL-B/C not required. | Select when cost sensitivity outweighs functional safety requirements and PWM output is unnecessary. |
| AMS AS5055A-BQFT | 12-bit SPI/I²C output, no SENT/PWM native support, requires external MCU for protocol translation; ±0.3° typical accuracy. | Suitable for embedded MCU-based systems with available GPIO and firmware resources for custom communication handling. | Choose only if system architecture mandates digital bus interface and can absorb added software complexity and latency. |
Compared with MLX90372GVS-ACE-350-SP, MLX90371GVS-ABD-350-SP reduces BOM cost but removes ASIL-C evidence and PWM flexibility, while AMS AS5055A-BQFT offers higher resolution but lacks automotive-grade SENT output and integrated diagnostics - making MLX90372GVS-ACE-350-SP optimal for safety-critical, production-ready automotive position sensing.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACE-350-SP?
The MLX90372GVS-ACE-350-SP uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input (NTC/gateway). This matches STD3 2.00 mm trim & form per ordering code -350. The PCB-less construction simplifies mechanical integration and improves thermal coupling in high-temperature locations.
Does MLX90372GVS-ACE-350-SP support both SENT and PWM output modes?
Yes, MLX90372GVS-ACE-350-SP supports selectable SENT (SAE J2716 APR2016 compliant) and PWM output modes via end-user programming. SENT mode delivers secure frames with CRC, diagnostics, and user data; PWM mode encodes position as duty cycle with configurable frequency and resolution. Both modes operate within the same -40°C to +160°C range.
What safety certifications apply to MLX90372GVS-ACE-350-SP?
MLX90372GVS-ACE-350-SP is certified to ISO26262 ASIL-C as a Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0. It includes hardware-level safety mechanisms: dual watchdogs (IWD/AWD), memory ECC, cyclic redundancy checks on SENT frames, and diagnostic cycle timing - all documented in Melexis' functional safety manual.
How does the Input pin (Pin 4) function in MLX90372GVS-ACE-350-SP?
In MLX90372GVS-ACE-350-SP's DMP-4 Pinout-B, Pin 4 (Input) serves as a configurable interface for NTC thermistors or analog/digital gateways. When used with an NTC, it enables real-time temperature compensation of magnetic sensitivity and offset - critical for maintaining accuracy in ride height or throttle sensors exposed to wide ambient swings.
What is the accuracy specification of MLX90372GVS-ACE-350-SP in standard angular mode?
In standard legacy mode (-300/-350 option code), MLX90372GVS-ACE-350-SP achieves ±0.5° typical angular accuracy over 0–360° at 25°C, with total error (including temperature drift and linearity) remaining within ±1.5° across -40°C to +160°C when paired with a properly designed magnetic circuit and calibrated in-system.
