Product details
Overview
MLX90372GVS-ACC-300-RE 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 is AEC-Q100 qualified for automotive throttle and pedal position sensing.
For engineers reviewing the MLX90372GVS-ACC-300-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed DMP-4 Pinout B configuration, ISO26262 ASIL-C safety compliance, SENT SAE J2716 APR2016 compliance, and real-world accuracy specs per legacy (-300) mode.
Technical Context
The MLX90372GVS-ACC-300-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angle decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning and piecewise linear (PWL) interpolation with up to 32 points.
It supports two timing modes: asynchronous acquisition (588 µs typical measurement period) for PWM and continuous SENT, and synchronous acquisition aligned to SENT frame timing (960 µs typical frame period). Output is configurable as SENT (3 µs tick, Secure Sensor format) or PWM with user-defined duty cycle resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - Validated for under-hood automotive environments including engine control modules and brake systems. |
| Supply Voltage | 4.5 V to 5.5 V (regulated mode) - Compatible with standard 5 V automotive power rails; includes undervoltage lockout at 3.9–4.25 V. |
| Supply Current | 8.0–10.5 mA - Optimized for low-power operation in battery-supplied or always-on vehicle subsystems. |
| Output Interface | SENT (SAE J2716 APR2016) or PWM - SENT delivers 48-bit ID + diagnostics; PWM offers direct analog-compatible timing with programmable resolution. |

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 enhanced EEPROM endurance and improved startup timing (11.2 ms safe startup vs. ACC's 12.4 ms). | Same angular/linear use cases; supports identical magnetic configurations and SENT/PWM protocols. | Select ACE-300 for new designs requiring extended program/erase cycles and tighter startup consistency. |
| MLX90371GDC-ABD-000-TU | SOIC-8 package, single-die, legacy Triaxis® architecture; lacks SENT Secure Sensor format, supports only PWM and analog ratiometric output. | Lower-cost alternative for non-diagnostic applications; not ASIL-C certified and lacks 48-bit ID or CRC-protected messaging. | Choose only where SENT diagnostics and ISO26262 traceability are not required; requires PCB layout change due to SOIC-8 footprint. |
Compared with MLX90372GVS-ACC-300-RE, the ACE-300 variant improves long-term reliability and startup predictability without altering pinout or functional behavior, while the MLX90371 offers cost reduction at the expense of safety certification and digital protocol capability.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACC-300-RE?
The MLX90372GVS-ACC-300-RE uses the DMP-4 (Dual Mould Package) with Pinout B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input. It is a PCB-less, surface-mount package with STD4 2.54 mm trim and form, optimized for high-volume automotive sensor modules.
Does MLX90372GVS-ACC-300-RE support SENT and PWM simultaneously?
No - the MLX90372GVS-ACC-300-RE supports either SENT or PWM output, selected during programming. SENT mode uses the Secure Sensor format per SAE J2716 APR2016 with CRC and diagnostics; PWM mode provides configurable duty cycle resolution and frequency, but not concurrently with SENT.
What is the accuracy specification for MLX90372GVS-ACC-300-RE in legacy mode?
In legacy (-300) mode, MLX90372GVS-ACC-300-RE achieves ±0.5° typical angular accuracy over 0–360° at 25°C, with total error bounded by ±1.2° across -40°C to +160°C when used with a properly calibrated magnet and housing per Melexis application guidelines.
Is MLX90372GVS-ACC-300-RE ISO26262 ASIL-C certified?
Yes - MLX90372GVS-ACC-300-RE is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC), meaning it provides documented safety mechanisms (watchdog, memory ECC, diagnostic cycles) that enable integration into ASIL-B or ASIL-C systems without requiring duplicate hardware.
Can MLX90372GVS-ACC-300-RE operate with battery-supplied voltage?
Yes - MLX90372GVS-ACC-300-RE supports battery operation (6–18 V) via internal regulation; however, the ACC-300 variant is configured for 5 V regulated mode by default. Battery mode requires reprogramming the WARM_ACT_HIGH parameter and verifying PTC thresholds per datasheet Table 10.
