Product details
Overview
MLX90372GVS-ACC-300-SP from Melexis is a monolithic Triaxis® Hall-effect 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 a PCB-less DMP-4 package with Pinout-A configuration for automotive pedal, throttle, and steering applications.
For engineers reviewing the MLX90372GVS-ACC-300-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional context, validated DMP-4 pin mapping, real-world accuracy specs per legacy mode (-300), SENT timing compliance (SAE J2716 APR2016), and direct alternative options for angular/linear position sensing in harsh environments.
Technical Context
The MLX90372GVS-ACC-300-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angle decoding from 0° to 360° or linear displacement without contact. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics with up to 32 points and configurable SENT frame structure (3 µs tick, no pause).
This variant uses the ACC chip revision in DMP-4 package (Pinout-A), supports legacy angular/linear position mode (-300 option code), and outputs SENT frames with embedded diagnostics, CRC, and 48-bit ID - all while maintaining AEC-Q100 qualification and robust stray-field immunity per standard mode specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive use without external thermal derating |
| Supply Voltage | 4.5 V to 5.5 V - regulated mode operation; supports battery input up to 18 V via internal PTC detection |
| Supply Current | 8.0–10.5 mA - typical current draw in legacy (-300) mode, enabling low-power ECU integration |
| Output Protocol | SENT (SAE J2716 APR2016) or PWM - selectable via programming; SENT includes error codes and user-defined values |
| Accuracy (Legacy) | ±0.5° (typ) angular error - specified for standard mode (-300) over full temperature range and lifetime |
| Magnetic Range | ±1 T - maximum flux density tolerance ensures reliability near high-current conductors or motors |
| Package | DMP-4 (Pinout-A) - PCB-less dual-mold package with 4 terminals: VSS, VDD, OUT, VSS - optimized for compact, high-vibration sensor assemblies |
Pinout & Package
DMP-4 package (Pinout-A) is a PCB-less, surface-mount dual-mold module with 4 solderable terminals and integrated decoupling capacitance. Designed for direct magnet coupling in space-constrained automotive sensors.
| 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 | Primary supply input - accepts 4.5–5.5 V regulated or 6–18 V battery input with internal regulation |
| 3 | OUT | SENT/PWM output driver - push-pull capable; supports open-drain configuration with external pull-up |
| 4 | VSS | Second ground terminal - reduces ground loop impedance and improves noise immunity in high-dV/dt environments |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx/By/Bz measurement enables true absolute position decoding without mechanical cam or gear constraints |
| Programmable PWL Transfer | Up to 32-point piecewise linear calibration allows precise compensation of non-ideal magnet geometry or mechanical hysteresis |
| SENT Secure Sensor Format | Embedded CRC, diagnostic flags, and 48-bit ID enable traceability, fault detection, and secure ECU communication |
| AEC-Q100 & ASIL-C | Qualified for automotive safety-critical systems; includes watchdog timers, memory ECC, and hardware self-test mechanisms |
| DMP-4 Stray-Field Immunity | Optimized magnetic path and internal concentrator reduce sensitivity to external fields - validated per standard (-300) mode spec |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-ACE-300-SP | Uses ACE chip revision (preferred for new designs); identical DMP-4 Pinout-A, same -300 mode, enhanced diagnostics and startup timing | No functional change in legacy angular/linear sensing; improved fail-safe state duration (9.8–11.0 ms vs 11.9–34.6 ms for ACC) | Select ACE-300 for new designs requiring extended lifecycle support and updated safety mechanisms. |
| MLX90363GDC-ABG-000-SP | SOIC-8 package, single-die, lower cost; supports only SENT (no PWM); ±0.8° accuracy in standard mode | Limited to less demanding applications; lacks DMP-4's vibration resistance and stray-field immunity | Choose when board-level assembly is preferred and packaging robustness is secondary to BOM cost. |
Compared with MLX90372GVS-ACC-300-SP, the ACE-300 offers identical functionality with improved safety timing and longer-term availability, while the MLX90363GDC-ABG-000-SP trades DMP-4 ruggedness and dual-output flexibility for SOIC-8 manufacturability and lower unit cost - making it suitable only where environmental stress is minimal.
