Product details
Overview
MLX90372GVS-ACC-300-RX 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 a PCB-less DMP-4 package with Pinout-A configuration for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90372GVS-ACC-300-RX datasheet, pinout, applications, or equivalent options, this page provides verified functional context, real-world timing behavior, output protocol compliance (SAE J2716 APR2016), stray-field robustness in legacy mode, and DMP-4 package-specific decoupling and startup characteristics.
Technical Context
The MLX90372GVS-ACC-300-RX implements a Triaxis® front end that measures Bx, By, and Bz magnetic field components simultaneously, enabling absolute angle decoding up to 360° or linear displacement without mechanical contact. Its on-chip DSP supports programmable piecewise linear (PWL) transfer characteristics with up to 32 points and configurable SENT frame structure (282-tick asynchronous mode).
This variant uses the ACC chip revision in DMP-4 package (Pinout-A), supporting SENT 3µs mode with standard capacitor configuration and legacy (-300) magnetic calibration-optimized for angular/linear applications where stray-field immunity is not required but high-temperature operation and compact PCB-less integration are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V (regulated mode); enables stable operation in 5 V automotive domains with ±10% tolerance. |
| Operating Temperature | -40°C to +160°C; qualified for under-hood and transmission-mounted position sensing without external cooling. |
| Output Protocol | SAE J2716 APR2016 SENT (asynchronous, 282-tick frame); delivers secure sensor data with CRC and diagnostics in single-wire format. |
| Accuracy (Legacy Mode) | ±0.5° typical angular error over full range; validated for throttle and steering wheel position feedback in production ECUs. |
| Startup Time | 11.2–12.4 ms safe startup (ACE/ADE only); ACC revision uses non-safe startup with no guaranteed fail-safe duration. |
| Package | DMP-4, Pinout-A (VSS–VDD–OUT–VSS); PCB-less dual-mold construction reduces footprint and eliminates solder joint reliability concerns. |
| Magnetic Sensing | Triaxis® 3D Hall front end; resolves absolute position from moving magnet geometry without requiring multi-die redundancy. |
Pinout & Package
DMP-4 package (PCB-less dual mold) with Pinout-A configuration: 4-terminal surface-mount module with integrated capacitors, designed for direct mounting onto flexible substrates or metal carriers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Analog/digital ground reference; must be connected to low-impedance chassis or substrate ground for EMC stability. |
| 2 | VDD | Main supply input (4.5–5.5 V); powers internal regulator generating 3.3 V analog rail (VDEC) and 1.85 V digital rail (VDDD). |
| 3 | OUT | SENT/PWM output driver; push-pull capable (25 mA short-circuit limit), compatible with 5 V pull-up or open-drain termination. |
| 4 | VSS | Second ground terminal; used for current return path separation and thermal dissipation in high-vibration environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Magnetic Sensing | Simultaneous Bx/By/Bz measurement enables single-die absolute position decoding without external concentrators or multi-sensor fusion. |
| Programmable PWL Transfer | Up to 32-point piecewise linear calibration allows precise compensation of magnet nonlinearity and mechanical hysteresis in custom assemblies. |
| SENT 3µs Asynchronous Mode | Fixed 282-tick frame timing ensures deterministic latency (<588 µs angle measurement period) independent of ECU clock synchronization. |
| Stray-Field Robustness (Legacy) | Optimized for standard magnetic circuits (e.g., diametrically magnetized ring magnets); avoids complex shielding in cost-sensitive throttle/pedal modules. |
| DMP-4 Pinout-A Integration | Eliminates PCB routing, solder joints, and decoupling capacitor placement-reducing BOM count and assembly steps in high-volume automotive sensors. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |

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-RX | Uses ACE chip revision with safe startup time (11.2–12.4 ms), enhanced diagnostics, and updated firmware; ACC lacks guaranteed fail-safe startup. | Required for new ASIL-C-compliant designs needing documented safe startup; ACC remains in production but not recommended for new designs. | Select ACE-300 for all new automotive programs requiring ISO26262 tool qualification evidence and traceable safety mechanisms. |
| MLX90363GDC-ABD-000-TU | SOIC-8 packaged 2D Hall position sensor; outputs analog ratiometric voltage (0.5–4.5 V) instead of SENT/PWM; no DSP or programmability. | Suitable for cost-sensitive non-safety applications (e.g., HVAC flap control) where digital diagnostics and high accuracy are unnecessary. | Choose MLX90363 only when SENT interface, ASIL-C compliance, or programmable linearity are not required-avoids DMP-4 integration complexity. |
Compared with MLX90372GVS-ACC-300-RX, the ACE-300 variant adds verified safe startup and extended diagnostic coverage essential for ASIL-C integration, while the MLX90363 offers simpler analog output at lower cost but forfeits SENT communication, programmability, and functional safety support.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACC-300-RX?
The MLX90372GVS-ACC-300-RX uses the DMP-4 (Dual Mould Package) with Pinout-A configuration: four terminals arranged as VSS–VDD–OUT–VSS. This PCB-less design integrates decoupling capacitance internally and is optimized for direct mounting on flex circuits or metal carriers in space-constrained automotive modules.
Does MLX90372GVS-ACC-300-RX support SAE J2716 SENT protocol?
Yes, MLX90372GVS-ACC-300-RX supports SAE J2716 APR2016 SENT in asynchronous mode with a fixed 282-tick frame (3 µs per tick), delivering 12-bit position data, 4-bit status, and 4-bit CRC per frame. It does not support SENT pause mode or fast SENT (1.5 µs tick) in this ACC-300 configuration.
What is the operating temperature range of MLX90372GVS-ACC-300-RX?
The MLX90372GVS-ACC-300-RX is rated for continuous operation from -40°C to +160°C ambient temperature, validated per AEC-Q100 Grade 0. This range supports placement in high-heat zones such as near engines, transmissions, and brake calipers without derating or external thermal management.
Is MLX90372GVS-ACC-300-RX certified for functional safety applications?
Yes, MLX90372GVS-ACC-300-RX is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC). It includes dual watchdog timers (IWD/AWD), memory ECC, and diagnostic cycle monitoring-but ACC revision lacks guaranteed safe startup time, requiring system-level validation for ASIL-C integration.
Can MLX90372GVS-ACC-300-RX be reprogrammed in-system?
Yes, MLX90372GVS-ACC-300-RX supports end-user programming via its SENT interface for output mode selection (SENT/PWM), transfer characteristic (4/8/16/32-point PWL), filtering, and diagnostic settings. Programming requires Melexis' PTM software and compatible programmer; factory calibration data remains locked in NVRAM.
