Product details
Overview
MLX90371GVD-EAC-300-TU from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute rotary or linear position output with 12-bit resolution, ±10-bit thermal accuracy, and programmable analog or PWM output. It operates from -40°C to +160°C, supports stray-field immunity in Standard/Legacy Mode (BCC-300), and is used in automotive throttle, pedal, and steering wheel position sensing.
For engineers reviewing the MLX90371GVD-EAC-300-TU datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package footprint, 4.5–5.5 V supply range, 440–462 µs latency, ISO 26262 ASIL-B safety compliance, and programmable piecewise-linear transfer characteristic with up to 32 segments.
Technical Context
The MLX90371GVD-EAC-300-TU implements Triaxis® Hall technology with on-chip DSP, ADC, and NVRAM to process raw 3-axis magnetic field data into calibrated position output. Its architecture includes a 12-bit analog output stage and a 12-bit PWM generator, both configurable via end-user programming of scaling, discontinuity point, and FIR/exponential filtering parameters.
This variant uses the DMP-4 package (dual mold, PCB-less), operates in Standard/Legacy Mode (BCC-300), and features reverse polarity and overvoltage protection on VDD, plus built-in diagnostic functions including broken-wire detection and intelligent watchdog. The device requires no external decoupling capacitor due to integrated VDEC functionality.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVD-EAC-300-TU | Same DMP-4 package and BCC-300 mode, but adds EEPROM-based user-programmable ID and enhanced diagnostic coverage | Required where traceable device identification or extended fault logging is mandated by OEM safety requirements | Select when ASIL-B compliance must include unique device serialization and deeper diagnostic reporting |
| AMS AS5055A-BQFT | 14-bit resolution, SPI interface only, no analog/PWM output; requires external MCU for signal conditioning | Suitable for new designs with available processing resources and no legacy analog ECU interface constraints | Choose if higher resolution and digital-only integration outweigh need for analog/PWM compatibility |
Compared with MLX90371GVD-EAC-300-TU, the MLX90372 offers expanded memory and diagnostics at identical footprint and pinout, while the AS5055A demands host MCU support and lacks native analog output - making MLX90371GVD-EAC-300-TU optimal for drop-in replacement in existing analog-signal architectures.

FAQ
What is the operating temperature range of the MLX90371GVD-EAC-300-TU?
The MLX90371GVD-EAC-300-TU is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports placement in high-temperature zones such as engine compartments, transmissions, and brake modules. Its thermal accuracy remains at 10-bit level across the full span, verified per Melexis datasheet Revision 004, Section 9.2.
Does the MLX90371GVD-EAC-300-TU require an external decoupling capacitor?
No, the MLX90371GVD-EAC-300-TU does not require an external decoupling capacitor. Its DMP-4 package integrates internal decoupling functionality via the VDEC architecture, eliminating the need for external 100 nF capacitors. This is confirmed in Section 15.3 of the datasheet and simplifies PCB layout for space-constrained automotive modules.
What output modes does the MLX90371GVD-EAC-300-TU support?
The MLX90371GVD-EAC-300-TU supports two configurable output modes: ratiometric analog voltage (0–100% VDD) and PWM (150–2000 Hz). Both are programmable via on-chip NVRAM and can be selected independently per application. The analog mode maintains compatibility with legacy potentiometer interfaces, while PWM enables noise-immune digital communication with microcontrollers.
Is the MLX90371GVD-EAC-300-TU certified for functional safety applications?
Yes, the MLX90371GVD-EAC-300-TU is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC). This certification covers hardware fault tolerance, diagnostic coverage, and failure mode analysis documented in Section 14 of the datasheet. It enables integration into ASIL-B or ASIL-C systems when combined with appropriate system-level safety mechanisms.
What magnetic configurations does the MLX90371GVD-EAC-300-TU support in Standard/Legacy Mode?
In Standard/Legacy Mode (BCC-300), the MLX90371GVD-EAC-300-TU supports both absolute rotary (0–360°) and absolute linear position sensing using standard diametrically or axially magnetized magnets. It maintains backward compatibility with prior-generation MLX90363 designs and does not require specialized stray-field immune magnet arrangements.
