Product details
Overview
MLX90372GVS-ACC-301-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, supports programmable transfer characteristics (up to 32-point PWL), and features ISO26262 ASIL-C safety compliance. It is used in automotive throttle, pedal, and steering wheel position sensing where stray-field immunity and robust non-contact measurement are required.
For engineers reviewing the MLX90372GVS-ACC-301-RX datasheet, pinout, applications, or equivalent options, this page provides verified technical context, package-specific pin definitions, real-world application mappings, and validated alternative options for angular/linear position sensing in high-reliability automotive systems.
Technical Context
The MLX90372GVS-ACC-301-RX implements Triaxis® Hall sensing to resolve all three magnetic field components (Bx, By, Bz), enabling absolute angle decoding from 0° to 360° or linear displacement without mechanical contact. Its on-chip DSP performs real-time signal conditioning, filtering, and piecewise-linear (PWL) transfer function mapping with up to 32 points.
This variant uses the DMP-4 package with Pinout-B configuration (VSS/VDD/OUT/Input), supports SENT per SAE J2716 APR2016 (3 µs tick mode), and includes built-in capacitors for simplified PCB-less integration. It is qualified to AEC-Q100 Grade 0 and rated for junction temperatures up to +175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
DMP-4 package (PCB-less dual mold), RoHS-compliant, face-down tape-and-reel delivery (RX packing form). Dimensions conform to STD1 2.54 trim and form (section 18.10).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | SENT or PWM output signal - drives external MCU input with configurable frame format and diagnostics. |
| 2 | VSS | Analog/digital ground reference - must be connected to low-impedance system ground for noise immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-ACE-301-RX | Uses ACE chip revision (preferred for new designs); identical DMP-4 Pinout-B, same -301 legacy mode, but enhanced diagnostics and updated ROM firmware. | Same angular/linear position use cases; improved diagnostic coverage for ASIL-C decomposition. | Select ACE-301 for new designs requiring full lifecycle support and latest safety mechanisms. |
| MLX90371GVS-ACC-301-RX | Single-die predecessor with identical DMP-4 Pinout-B and -301 option code; lacks dual-die redundancy and some SENT enhancements in MLX90372. | Valid for legacy retrofit where footprint and output compatibility are mandatory; no ASIL-C SEooC claim. | Choose only for backward-compatible replacements where MLX90372's enhanced safety and diagnostics are not required. |
Compared with MLX90372GVS-ACC-301-RX, the ACE-301 offers extended diagnostic coverage and longer manufacturer support, while the MLX90371GVS-ACC-301-RX provides pin-identical drop-in replacement capability at lower functional safety assurance - making ACE-301 optimal for new ASIL-C designs and MLX90371 suitable for cost-sensitive legacy upgrades.

FAQ
What is the package type and mounting configuration of MLX90372GVS-ACC-301-RX?
The MLX90372GVS-ACC-301-RX uses the DMP-4 (Dual Mould Package) with Pinout-B configuration - a PCB-less, four-terminal surface-mount device with integrated decoupling capacitors. It is delivered face-down on tape-and-reel (RX packing form) and requires direct soldering to the host board with VSS, VDD, OUT, and Input terminals aligned to matching pads per section 3.4 of the datasheet.
Does MLX90372GVS-ACC-301-RX support both SENT and PWM output modes?
Yes, MLX90372GVS-ACC-301-RX supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selectable via end-user programming. The default factory setting is SENT with 3 µs tick time; PWM mode provides configurable duty cycle for analog-like interface with microcontrollers lacking SENT receivers.
What is the functional safety qualification status of MLX90372GVS-ACC-301-RX?
MLX90372GVS-ACC-301-RX is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0. It includes hardware safety mechanisms such as watchdog timers (IWD/AWD), memory ECC, and diagnostic cycles - enabling its use in ASIL-B or ASIL-C system architectures when integrated per Melexis' safety manual.
How does the MLX90372GVS-ACC-301-RX achieve stray-field immunity in automotive environments?
The MLX90372GVS-ACC-301-RX achieves stray-field immunity through Triaxis® 3D Hall sensing combined with on-chip DSP algorithms that reject orthogonal interference. In -300/-301 legacy mode, it maintains ±0.3° accuracy under ±1 T external magnetic fields - validated for placement near high-current actuators without magnetic shielding.
Can MLX90372GVS-ACC-301-RX be reprogrammed in-system for different transfer characteristics?
Yes, MLX90372GVS-ACC-301-RX supports full end-user programming via its SENT interface, including configuration of up to 32-point PWL transfer functions, output mode selection, diagnostic thresholds, and magnetic front-end parameters. Reprogramming requires Melexis' PTC programming tool and is supported throughout the device's operational lifetime.
