Product details
Overview
MLX90372GVS-ACE-100-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary position sensing with stray-field immunity, operating from -40°C to +160°C, delivering SENT or PWM output, and qualified to AEC-Q100 Grade 0. It enables non-contacting throttle and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90372GVS-ACE-100-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed angular stray-field immune mode (-100), SENT 3µs timing compliance, and real-world functional safety context per ISO 26262 ASIL-C SEooC.
Technical Context
The MLX90372GVS-ACE-100-RE implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components to compute absolute angular position without mechanical wear. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics up to 32 points and configurable SENT frame encoding per SAE J2716 APR2016.
This variant uses DMP-4 package (Pinout-A), operates in Angular Rotary Strayfield Immune - Low Field Variant mode (-100 code), and delivers SENT output with 3µs tick time, fixed capacitor configuration, and STD1 1.27 trim & form per section 18.9. It excludes dual-die redundancy and TSSOP-16 isolation features.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - Supports under-hood automotive placement without external thermal derating. |
| Supply Voltage | 4.5–5.5 V (regulated) - Compatible with standard 5 V automotive ECUs; battery mode (6–18 V) requires WARM_ACT_HIGH config. |
| Supply Current | 9.0–12.6 mA - Valid for -100 stray-field immune mode; enables low-power ECU subsystem integration. |
| Output Protocol | SENT (SAE J2716 APR2016) or PWM - SENT supports Secure Sensor format with error codes and user-defined values; PWM offers analog-compatible interface. |
| Magnetic Mode | Angular Rotary Strayfield Immune (-100) - Rejects orthogonal interference fields up to ±1 T; validated for throttle pedal environments with nearby solenoids. |
| Accuracy | ±0.3° typical angle error - Achieved via on-chip DSP compensation and factory-trimmed IMC; specified over full temperature range. |
| Functional Safety | ISO 26262 ASIL-C SEooC - Includes internal watchdogs (IWD/AWD), memory ECC, and diagnostic cycle timing (DCTANA = 34 µs). |
Pinout & Package
DMP-4 package (PCB-less dual mold, RoHS-compliant), Pinout-A configuration, STD1 1.27 mm trim & form (per section 18.9). No external decoupling capacitors required - built-in capacitance supports stable operation in space-constrained modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Analog/digital ground reference; must be connected to PCB ground plane for EMC robustness. |
| 2 | VDD | Primary supply input (4.5–5.5 V); internal regulator generates 3.3 V analog rail (VDEC). |
| 3 | OUT | Programmable digital output: SENT (push-pull) or PWM (open-drain/push-pull); supports 3 µs tick timing. |
| 4 | VSS | Second ground terminal; improves current return path symmetry and reduces ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Front End | Simultaneous Bx/By/Bz measurement enables true 3D magnetic field decoding for absolute angle without external magnets or flux concentrators. |
| Stray-Field Immunity (-100) | Rejects interfering magnetic fields orthogonal to sensing axis up to ±1 T - critical for throttle position sensors near high-current actuators. |
| SENT Secure Sensor Format | Embedded CRC, status flags, and user-defined payload enable fault-aware communication with ECU without additional protocol layering. |
| Programmable PWL Transfer | Up to 32-point piecewise linear calibration allows precise linearization of non-ideal magnet trajectories - eliminates post-assembly software correction. |
| DMP-4 Integrated Capacitance | Built-in decoupling eliminates external 100 nF ceramic capacitor - reduces BOM count and PCB area in compact sensor modules. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|
Use Scenario: Real-time detection of accelerator pedal angle in gasoline/diesel powertrains with ECU closed-loop torque control. IC Role / Device Role / Timing Role: Absolute angular position processor delivering SENT frames every 960 µs (two-angle synchronous mode) with <20 ms watchdog timeout. Use Value: ±0.3° accuracy and stray-field immunity ensure reliable torque demand interpretation despite proximity to starter solenoid and alternator fields. |
Use Scenario: Non-contact measurement of brake or clutch pedal displacement in electronic braking systems (EBS) and automated manual transmissions (AMT). IC Role / Device Role / Timing Role: Linear-to-angular converter using custom magnet geometry; outputs PWM signal with 10–90% duty cycle mapped to 0–100% pedal travel. Use Value: DMP-4's PCB-less construction enables direct integration into pedal assembly housings, reducing mechanical tolerance stack-up and calibration drift. |
| Steering Wheel Position Sensing | Ride Height Position Sensing |
Use Scenario: Detection of absolute steering angle for EPS assist control and lane-keeping assist (LKA) systems. IC Role / Device Role / Timing Role: High-reliability angular sensor with ISO 26262 ASIL-C SEooC compliance; SENT output includes diagnostic status bits for ECU fault tree analysis. Use Value: Dual watchdog timers (IWD/AWD) and memory ECC provide fail-safe state activation within 34.6 ms after single-event upset - meets ASIL-C timing constraints. |
Use Scenario: Monitoring suspension travel in adaptive air ride systems to adjust damping and vehicle level control. IC Role / Device Role / Timing Role: Linear position transducer using axial magnet motion; configured for -100 mode to reject interference from adjacent ABS wheel speed sensors. Use Value: Factory-programmed 16-point PWL transfer characteristic compensates for nonlinear spring rate, enabling direct ECU lookup without interpolation. |
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-ACE-100-RE | Single-die architecture; no SENT Secure Sensor format; PWM-only output; lower diagnostic coverage. | Lacks SENT error coding and user payload; suitable only for cost-sensitive non-safety-critical linear sensing. | Select only if SENT protocol and ASIL-C diagnostics are unnecessary and BOM cost reduction is primary. |
| AMS AS5055A-BQFT | Rotary encoder IC with SPI/I²C interface; no stray-field immunity; ±0.5° typical accuracy; 3.3 V only. | Requires external MCU for SENT translation; unsuitable for high-interference under-hood locations. | Choose only for board-level designs with dedicated microcontroller and shielded magnet assemblies. |
Compared with MLX90372GVS-ACE-100-RE, MLX90371GVS-ACE-100-RE omits SENT security features and functional safety mechanisms, while AMS AS5055A-BQFT lacks integrated stray-field rejection and automotive-grade temperature range - making MLX90372GVS-ACE-100-RE the sole option meeting full AEC-Q100 Grade 0, ASIL-C, and SENT 3µs requirements in DMP-4 form factor.
