Product details
Overview
MLX90374GVS-ABC-300-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers dual-output SENT + programmable switch signals, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, AEC-Q100 qualification, and supports stray-field immune operation in legacy angular/linear configurations. It enables non-contacting potentiometer replacement in automotive throttle and pedal systems.
For engineers reviewing the MLX90374GVS-ABC-300-SP datasheet, pinout, applications, or equivalent options, key selection criteria include DMP-4 package compatibility, SENT protocol compliance (SAE J2716 APR2016), dual-output redundancy architecture, programmable transfer characteristic (PWL up to 32 points), and robustness against external magnetic interference.
Technical Context
The MLX90374GVS-ABC-300-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, an analog-to-digital signal conditioner, and a DSP for real-time angle decoding. Its output stage supports either dual PWM or SENT + programmable switch modes with configurable error reporting and diagnostics.
In legacy mode (-300 option code), it delivers standard angular/linear position measurement with ±0.5° typical accuracy, 1.73–2.25 ms average latency (FIR11/FIR1111 filters), and SENT frame periods of 930–960 µs (3 µs tick, two-angle-per-frame). Startup time to first valid angle is 6.48–6.99 ms depending on T_FRAME configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - Enables under-hood automotive deployment without external thermal shielding |
| Supply Voltage | 4.5–5.5 V (regulated) or 6–18 V (battery) - Supports both 5 V microcontroller interfaces and direct 12 V vehicle battery connection |
| Output Modes | SENT (SAE J2716 APR2016) + programmable switch - Provides high-resolution serial data with CRC and fault codes plus discrete switching capability |
| Accuracy | ±0.5° typical (legacy mode) - Sufficient for throttle/pedal position feedback in ASIL-B/C systems |
| Latency | 1.73–2.25 ms (FIR11/FIR1111) - Matches real-time control loop timing requirements for engine management |
| Package | DMP-4 (PCB-less dual mold) - Reduces system cost and footprint; eliminates PCB routing for sensor head assembly |
| Safety | ISO26262 ASIL-C SEooC - Allows integration into functional safety architectures without requiring additional hardware-level decomposition |
Pinout & Package
DMP-4 is a PCB-less dual-mold package with 4 terminals: OUT1, VSS, VDD, and OUT2. It enables direct solder-mounting onto flexible substrates or metal leads, eliminating interposer PCBs and reducing mechanical stack height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Primary SENT or PWM output - Carries primary position data or diagnostic status; open-drain or push-pull configurable |
| 2 | VSS | Digital ground reference - Shared return path for digital logic and output drivers; must be low-impedance to minimize noise coupling |
| 3 | VDD | Supply input (4.5–18 V) - Powers internal regulator, Hall front end, DSP, and output drivers; includes overvoltage/undervoltage detection |
| 4 | OUT2 | Programmable switch or secondary output - Configurable as active-low switch (e.g., end-of-travel flag) or redundant SENT/PWM channel |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous Bx/By/Bz measurement enables true 3D magnetic field decoding - eliminates need for external concentrators or multi-die solutions in rotary/linear applications |
| SENT + Switch Dual Output | Combines high-fidelity serial position data with deterministic discrete signaling - supports both closed-loop control and fail-safe state indication in same device |
| Stray-Field Immune Legacy Mode | Option code -300 configures magnetic sensitivity for angular/linear use cases with built-in compensation - maintains accuracy in magnetically noisy environments (e.g., near motors or solenoids) |
| 48-bit ID Number | Uniquely identifies each unit at production - enables traceability, calibration data binding, and counterfeit prevention in Tier 1 supply chains |
| Safe Startup Sequence | TSafeStup = 11.2–12.4 ms diagnostic cycle before first valid output - ensures integrity of internal registers and analog chain prior to system initialization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90375GVS-ABC-300-SP | Higher resolution (14-bit SENT vs. 12-bit), extended temperature range (+175°C junction), updated DSP firmware | Targeted for next-gen ADAS actuators requiring tighter angular tolerance (<±0.3°) and higher thermal margin | Select MLX90375 when upgrading for improved accuracy or extended thermal envelope; not drop-in due to firmware differences |
| AMS AS5055A-BQFT | 12-bit SPI/I²C output only, no SENT or PWM; lacks ASIL-C certification and stray-field immunity tuning | Suitable for industrial encoders or non-safety-critical consumer devices where serial interface suffices | Choose AS5055A only for cost-sensitive, non-automotive designs without functional safety or EMI robustness requirements |
Compared with MLX90374GVS-ABC-300-SP, the MLX90375 offers enhanced resolution and thermal margin but requires firmware revalidation, while the AS5055A provides lower-cost serial interfacing at the expense of automotive-grade safety, redundancy, and magnetic immunity.

It supports both synchronous (with pause) and asynchronous SENT modes, and delivers enhanced messages containing error codes and calibrated position values.
What does the "-300" option code signify in MLX90374GVS-ABC-300-SP?
The "-300" option code indicates legacy angular/linear position mode - a standardized configuration optimized for general-purpose rotary (0–360°) and linear displacement sensing without specialized stray-field immunity tuning. It enables consistent performance across diverse magnet geometries and is the default choice for throttle, pedal, and steering applications where magnetic environment is controlled.
Is the MLX90374GVS-ABC-300-SP qualified for automotive use, and what safety standards does it meet?
