Product details
Overview
MLX90372GVS-ACE-300-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 certification, and uses DMP-4 (PCB-less dual mold) packaging with Pinout-A configuration.
For engineers reviewing the MLX90372GVS-ACE-300-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, package-specific pin definitions, real-world automotive use cases, and validated alternative options for pedal, throttle, and steering wheel position sensing.
Technical Context
The MLX90372GVS-ACE-300-RE implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling robust absolute angle decoding without mechanical contact. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics with up to 32 points and configurable SENT frame structure per SAE J2716 APR2016.
This variant uses the ACE chip revision in DMP-4 package (Pinout-A), configured for legacy angular/linear mode (-300 option code), SENT 3µs timing, standard capacitor configuration, and STD1 1.27 trim/form. It lacks full redundancy (unlike TSSOP-16 GO variants) and does not support NTC/gateway functionality (reserved for Pinout-B).
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 control units. |
| Supply Voltage | 4.5 V to 5.5 V (regulated mode) - compatible with standard 5 V automotive power rails; supports battery mode (6–18 V) via configuration. |
| Supply Current | 8.0–10.5 mA - optimized for low-power operation in continuous sensing applications such as ride height monitoring. |
| Output Protocol | SENT (SAE J2716 APR2016) or PWM - SENT enables secure, error-coded serial communication; PWM offers simple analog-compatible interface. |
| Magnetic Sensing | Bx/By/Bz triaxial detection - enables absolute position measurement from rotating or linearly moving magnets without physical contact. |
| Safety Certification | ISO26262 ASIL-C Safety Element out of Context - supports functional safety integration in ASIL-B/C systems without requiring additional hardware redundancy. |
| Accuracy Mode | Standard/Legacy (-300) - provides ±1.0° typical angular accuracy over full 360° range, suitable for throttle and pedal position feedback. |
Pinout & Package
DMP-4 package (PCB-less dual mold), RoHS-compliant, STD1 1.27 trim/form, Pinout-A configuration - designed for direct magnet coupling with minimal board footprint and no external decoupling capacitors required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Analog/digital ground reference; must be connected to system ground for stable bias and EMC performance. |
| 2 | VDD | Main supply input (4.5–5.5 V); powers internal regulator generating 3.3 V analog rail and 1.85 V digital rail. |
| 3 | OUT | Programmable SENT or PWM output; push-pull driver capable of driving 3 kΩ PWM load or 10–55 kΩ SENT pull-up. |
| 4 | VSS | Second ground terminal - improves current return path symmetry and reduces ground bounce in high-noise environments. |
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 complex magnet geometries. |
| Programmable PWL Transfer | Up to 32-point piecewise linear calibration allows precise linearization of non-ideal magnet trajectories in throttle or float-level sensors. |
| SENT Secure Sensor Format | Embedded CRC, diagnostic flags, and user-defined data fields enable fault-detecting communication compliant with modern automotive ECU requirements. |
| Stray-Field Immunity | Configurable via option code - this -300 variant supports legacy mode but can be upgraded to stray-field immune variants (-100/-200) via programming. |
| Integrated Regulator | On-chip 3.3 V analog and 1.85 V digital supplies reduce external component count - eliminates need for discrete LDOs in space-constrained modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GDC-ACE-300-RE | SOIC-8 package with 8 pins; includes dedicated VDEC decoupling pin and separate analog/digital grounds. | Preferred for PCB-mounted designs requiring test access, thermal margin, or compatibility with legacy Triaxis® layouts. | Select when board space permits SOIC-8 and decoupling flexibility is needed; not pin-compatible with DMP-4. |
| MLX90372GO-ACE-300-RE | TSSOP-16 dual-die package with full hardware redundancy, isolation resistance >4 MΩ between dice, and doubled supply current. | Required for ASIL-D systems or where hardware-level fault tolerance is mandated beyond ASIL-C software diagnostics. | Choose only when dual-die redundancy is contractually required; incompatible pinout and larger footprint than DMP-4. |
Compared with MLX90372GVS-ACE-300-RE, the SOIC-8 variant offers greater layout flexibility and testability, while the TSSOP-16 provides hardware redundancy for higher safety integrity - neither is pin-compatible, and both require PCB redesign for substitution.
