Product details

Overview

MLX90372GVS-ACC-308-RE from Melexis is a monolithic Triaxis® magnetic position processor IC for absolute rotary and linear position sensing. It integrates a 3-axis Hall front end, DSP-based signal conditioning, SENT/PWM output stage, and operates from -40°C to +160°C with AEC-Q100 qualification and ISO 26262 ASIL-C safety certification. It delivers robust stray-field immunity in legacy mode and supports programmable transfer characteristics for automotive pedal, throttle, and steering applications.

For engineers reviewing the MLX90372GVS-ACC-308-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4 Pinout-A), confirmed SENT 3µs timing, factory-default legacy-mode accuracy (±0.5° typical), dual-ground architecture, and validated alternatives for angular position sensor design.

Technical Context

The MLX90372GVS-ACC-308-RE implements continuous asynchronous angle acquisition with fixed T_angleMeas = 588 µs and uses internal 24 MHz main clock (±5% thermal/lifetime drift). Its Triaxis® Hall front end measures B_x, B_y, and B_z components simultaneously to compute absolute angular position without mechanical contact.

This variant uses DMP-4 package (Pinout-A), features SENT output compliant with SAE J2716 APR2016, and is configured in Standard/Legacy Mode (-300 option code) with 4-point PWL transfer characteristic. It includes integrated diagnostics (IWD/AWD timeout = 20 ms), regulated V_DEC = 3.3 V, and operates at 4.5–5.5 V supply with 9.0–12.6 mA current draw.

1	VSS	Analog/digital ground reference; must be low-impedance connection to system GND.
2	VDD	Primary power input (4.5–5.5 V); requires local 100 nF decoupling per datasheet section 15.3.
3	OUT	SENT serial output (push-pull); drives standard 10 kΩ pull-up to 5 V; supports 125 kbps frame rate.
4	VSS	Second ground terminal - improves EMC performance and reduces ground loop noise in noisy environments.

Key Features

Feature	Design Value
Triaxis® 3D Hall Sensing	Simultaneous B_x/B_y/B_z measurement enables true absolute angle decoding from single moving magnet - eliminates need for multi-die or gear-based solutions.
Programmable Transfer Characteristic	Factory-configured 4-point PWL curve for linearized output across full 0–360° range - reduces host MCU calibration burden.
SENT Output with Diagnostics	Embedded CRC, error flags, and user-defined data fields in every frame - enables real-time fault detection without additional interface logic.
ASIL-C Safety Element	Includes hardware watchdogs (IWD/AWD), memory ECC, and diagnostic cycle management - satisfies decomposition requirements for ASIL-D systems.

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-308-RE	Uses ACE chip revision (preferred for new designs); identical DMP-4 Pinout-A, same -300 legacy mode, but includes updated firmware with enhanced diagnostics and tighter timing tolerances.	Same use cases; better long-term supply stability and extended lifecycle support.	Select ACE-308 for new designs requiring full Melexis product roadmap alignment and latest safety mechanism updates.
MLX90363GSO-ABD-100-SP	SOIC-8 packaged Triaxis® IC with SENT output; lower temperature grade (-40°C to +150°C); no ASIL-C certification; uses 3-point linearization instead of PWL.	Suitable for non-safety-critical industrial linear/rotary sensing where cost and PCB space are prioritized over automotive qualification.	Choose only if AEC-Q100 and ASIL-C are not required; verify compatibility with existing SOIC-8 footprint and thermal constraints.

Compared with MLX90372GVS-ACC-308-RE, the ACE-308 offers improved long-term reliability and updated safety mechanisms, while the MLX90363 provides cost-efficient SOIC-8 implementation at the expense of automotive qualification and advanced diagnostics - making ACC-308 optimal for legacy-design continuity in certified systems.

FAQ

What is the operating temperature range of the MLX90372GVS-ACC-308-RE?

The MLX90372GVS-ACC-308-RE is qualified for operation from -40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. This range is validated for under-hood and transmission-mounted applications where sustained high-temperature exposure occurs. The DMP-4 package's thermal resistance and internal regulator stability ensure consistent performance across the full range without derating.

Does the MLX90372GVS-ACC-308-RE support PWM output in addition to SENT?

Yes, the MLX90372GVS-ACC-308-RE supports both SENT and PWM output modes via end-user programming. However, this specific ACC-308 variant is factory-configured for SENT 3 µs mode (per ordering code definition in Table 2). PWM functionality remains accessible through reprogramming but requires compatible host firmware and external pull-up/pull-down resistors per datasheet section 13.1.

Is the MLX90372GVS-ACC-308-RE pin-compatible with other MLX90372 package variants?

No - the MLX90372GVS-ACC-308-RE uses DMP-4 Pinout-A (VSS-VDD-OUT-VSS), which is mechanically and electrically distinct from SOIC-8 (8-pin) and TSSOP-16 (16-pin) variants. While all share the same core functionality, PCB layout, termination method, and grounding scheme differ significantly; no direct footprint compatibility exists between DMP-4 and leaded packages.

What magnetic configurations does the MLX90372GVS-ACC-308-RE support?

The MLX90372GVS-ACC-308-RE is configured in Standard/Legacy Mode (-300 option code), supporting both absolute rotary (0–360°) and linear position sensing using conventional diametric or axial magnet arrangements. It does not include the enhanced stray-field immunity features of -100/-200/-500 variants, so magnet placement must follow standard Triaxis® guidelines in sections 18.15–18.16 of the datasheet.

How is functional safety implemented in the MLX90372GVS-ACC-308-RE?

The MLX90372GVS-ACC-308-RE implements ISO 26262 ASIL-C as a Safety Element out of Context (SEooC), featuring independent intelligent and absolute watchdogs (20 ms timeout), memory ECC for NVRAM, cyclic redundancy checks on SENT frames, and diagnostic cycle time control. These mechanisms are hardware-enforced and require no host MCU intervention to meet ASIL-C requirements when integrated into higher-level ASIL-D systems.
