Product details
Overview
MLX90372GVS-ACC-301-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC in DMP-4 package (Pinout-B), delivering absolute rotary or linear position sensing via SENT 3µs output with programmable transfer characteristic and stray-field robustness. It operates from -40°C to +160°C, supports 4.5–5.5 V regulated supply, draws 8.0–10.5 mA, and meets ISO 26262 ASIL-C as a safety element out of context.
For engineers reviewing the MLX90372GVS-ACC-301-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DMP-4 Pinout-B), confirmed SENT/PWM output modes, validated automotive-grade accuracy specs (±0.3° typical angular error), functional safety architecture, and real-world use cases including throttle and pedal position sensing.
Technical Context
The MLX90372GVS-ACC-301-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling contactless absolute angle measurement up to 360° or linear displacement. Its on-chip DSP performs real-time signal conditioning, piecewise linear (PWL) interpolation (up to 32 points), and SENT frame encoding per SAE J2716 APR2016.
This variant uses the ACC chip revision in DMP-4 Pinout-B configuration (VDD, VSS, OUT, Input), where the Input pin serves as NTC or analog/digital gateway. It operates in legacy/standard mode (-300 option code), supporting SENT 3µs timing with configurable frame structure and failsafe startup within 12.4 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V (regulated mode); enables stable operation in automotive 5 V domains without external LDO. |
| Supply Current | 8.0–10.5 mA (legacy mode); determines low-power suitability for battery-backed or always-on vehicle subsystems. |
| Operating Temp | -40°C to +160°C; qualified for under-hood automotive locations including throttle bodies and suspension modules. |
| Output Protocol | SENT 3 µs tick time (SAE J2716 APR2016); provides high-resolution, error-coded serial position data with CRC. |
| Accuracy | ±0.3° typical angular error (legacy mode); ensures precise pedal or steering wheel position feedback for closed-loop control. |
| Package | DMP-4 Pinout-B (4-pin PCB-less dual mold); enables direct magnet coupling, compact mounting, and integrated ESD protection. |
| Safety Certification | ISO 26262 ASIL-C SEooC; supports integration into ASIL-B/C systems without requiring additional hardware redundancy. |
Pinout & Package
DMP-4 package (PCB-less dual mold) with Pinout-B configuration: compact 4-pin surface-mount form factor optimized for direct integration into magnet assemblies; no PCB required, RoHS-compliant, thermal performance rated for TJ ≤ 175°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | SENT or PWM output signal; push-pull capable, supports 3 µs SENT frames or variable-duty PWM with diagnostics. |
| 2 | VSS | Analog/digital ground reference; must be connected to low-impedance chassis or system ground for EMC stability. |
| 3 | VDD | Primary power supply input (4.5–5.5 V); internal regulator generates 3.3 V analog rail (VDEC). |
| 4 | Input | NTC or analog/digital gateway input; used for temperature compensation or auxiliary sensor interface in Pinout-B config. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous Bx, By, Bz detection enables true 3D magnetic field decoding for absolute position without mechanical stops or gears. |
| Programmable PWL Transfer | Up to 32-point piecewise linear calibration allows precise linearization of non-ideal magnet trajectories in custom mechanical layouts. |
| SENT Secure Sensor Format | Embedded error codes, status flags, and user-defined payload fields enable robust diagnostics and traceability in safety-critical ECUs. |
| Stray-Field Immunity | Legacy mode (-300) maintains ±0.3° accuracy under external magnetic interference up to ±10 mT - sufficient for most engine bay environments. |
| Fast Startup & Fail-Safe | Valid angle output within 12.4 ms; failsafe state duration (9.8–34.6 ms) ensures deterministic behavior after digital fault detection. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|
|

Use Value: DMP-4 package allows direct magnet integration into compact suspension housings; stray-field immunity prevents interference from nearby motors or solenoids. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-ACE-300-RE | Uses ACE chip revision (preferred for new designs); identical DMP-4 Pinout-B, same -300 legacy mode, but improved startup timing and diagnostic coverage. | Same throttle/pedal/steering use cases; enhanced functional safety features align better with ASIL-B system integration requirements. | Select ACE-300 for new designs requiring extended lifecycle support and updated safety mechanisms per ISO 26262. |
| MLX90371GSO-ABD-100-SP | SOIC-8 package, single-die, SENT-only output; lacks Input pin functionality and DMP-4's PCB-less integration; lower temperature rating (–40°C to +150°C). | Suitable for cost-sensitive non-safety-critical applications (e.g., HVAC damper control); not qualified for ASIL-C or under-hood 160°C environments. | Choose only if board space permits SOIC-8 and application does not require NTC interface or full ASIL-C compliance. |
Compared with MLX90372GVS-ACC-301-RE, the ACE-300 offers superior functional safety readiness and longer production support, while the MLX90371GSO-ABD-100-SP trades packaging flexibility and safety certification for simpler layout and lower cost in less demanding environments.
