Product details
Overview
MLX90374GVS-ABC-300-RE 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 or redundant PWM signals, supports -40°C to +160°C operation, features ISO26262 ASIL-C safety compliance, and enables stray-field-immune non-contact sensing in automotive throttle, pedal, and steering applications.
For engineers reviewing the MLX90374GVS-ABC-300-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed dual-output timing modes (SENT/switch), validated AEC-Q100 qualification, exact pin functions per DMP-4 layout, and two field-validated alternative parts with documented functional trade-offs.
Technical Context
The MLX90374GVS-ABC-300-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, an analog-to-digital signal conditioner, and a DSP for real-time angle decoding. Its architecture supports both continuous asynchronous acquisition (for PWM and SENT without pause) and synchronous acquisition (for SENT with pause), with configurable frame lengths (e.g., 282–330 ticks) and filter options (FIR11/FIR1111).
It implements dual independent output stages: one SENT interface compliant with SAE J2716 APR2016 (1.5/3/6 µs tick time), and one programmable open-drain switch with 40–90 mA short-circuit current capability. Safety mechanisms include intelligent and absolute watchdogs (20 ms timeout), diagnostic cycle times (20 ms digital, 34 ms analog), and fail-safe state duration (9.8–34.6 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - Validated for under-hood automotive environments without derating. |
| Supply Voltage | 4.5–5.5 V (regulated) or 6–18 V (battery) - Dual-mode supply supports 5 V ECUs and 12 V battery systems. |
| Output Modes | SENT + programmable switch OR dual PWM - Configurable at system level; SENT includes CRC, error codes, and user-defined values. |
| Accuracy Mode | Legacy / Angular Rotary / Linear position (-300 option code) - Factory-configured for broad-angle or linear displacement decoding. |
| Safety Certification | ISO26262 ASIL-C SEooC - Enables integration into ASIL-B/C systems without requiring additional hardware redundancy. |
| Magnetic Immunity | Stray-field robustness - Achieved via on-chip IMC and differential Triaxis® sensing; no external shielding required in typical layouts. |
| Startup Time | 6.99 ms (SENT, 1 angle/frame) to 12.4 ms (safe startup) - Determines minimum ECU wake-up latency in start-stop systems. |
Pinout & Package
DMP-4 package: PCB-less dual-mold construction with 4 terminals, optimized for direct magnet coupling and high-temperature mounting (e.g., on transmission housings or suspension arms). No external decoupling capacitors required - internal VDEC regulation provided.

|---|---|---|
| 1 | OUT1 | Primary SENT output or PWM channel 1 - Drives host ECU's SENT receiver or PWM input; supports 1.5/3/6 µs tick timing. |
| 2 | VSS | Digital/analog ground reference - Single ground plane required; no separation needed between digital and analog sections. |
| 3 | VDD | Power supply input - Accepts 4.5–18 V; internal regulator generates stable 3.3 V analog rail (VDEC) and 1.85 V digital rail (VDDD). |
| 4 | OUT2 | Programmable switch output - Open-drain, 40–90 mA sink capability; configurable as fault indicator, enable signal, or secondary position status. |

Use Value: Maintains accuracy despite proximity to motor windings and high-current cables; enables secure firmware updates via unique device ID. |
Use Scenario: Detecting vertical suspension travel in air-sprung commercial vehicles for automatic leveling and load compensation. IC Role / Device Role / Timing Role: Linear position sensor using off-axis magnet configuration; delivers PWM output synchronized to vehicle CAN bus cycles for coordinated damping control. Use Value: Replaces LVDTs with higher reliability, lower power, and immunity to oil contamination or vibration-induced drift. |
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-RE | Higher-resolution 16-bit SENT output; enhanced thermal stability (±0.5° over -40°C to +160°C); same DMP-4 package and pinout. | Required where <0.8° total accuracy is mandated (e.g., steer-by-wire torque overlay). | Select when tighter angular accuracy and extended diagnostic coverage justify cost premium. |
| TAS57xx series (e.g., TAS5756M) | Not a position sensor - audio amplifier IC with integrated DSP; incompatible function and interface. | N/A - not suitable for position sensing; included only due to common prefix confusion in distributor search results. | Avoid - functional mismatch; verify part number prefix before sourcing. |
Compared with MLX90374GVS-ABC-300-RE, MLX90375GVS-ABC-300-RE offers improved angular accuracy and expanded SENT payload capacity but shares identical packaging, safety architecture, and magnetic front-end design - enabling drop-in replacement where resolution is the limiting factor. The TAS57xx series is functionally unrelated and must be excluded from position-sensing BOMs.

FAQ
What is the package type and lead configuration for MLX90374GVS-ABC-300-RE?
The MLX90374GVS-ABC-300-RE uses the DMP-4 (Dual Mold Package) with four terminals: OUT1, VSS, VDD, and OUT2. It has straight leads (STD1 1.27 mm pitch) per ordering code "300", requires no PCB, and mounts directly onto metal housings or brackets. Lead finish is matte tin, RoHS-compliant.
Does MLX90374GVS-ABC-300-RE support both SENT and PWM output simultaneously?
No - MLX90374GVS-ABC-300-RE supports either dual PWM output OR SENT plus programmable switch output. The mode is selected during programming via the WARM_ACT_HIGH parameter and cannot be dynamically switched in operation. SENT mode includes full SAE J2716 APR2016 compliance with CRC and error reporting.
What magnetic configurations does the -300 option code enable for MLX90374GVS-ABC-300-RE?
The -300 option code configures MLX90374GVS-ABC-300-RE for Legacy / Angular Rotary / Linear position sensing - supporting both 0–360° rotary motion (e.g., throttle valves) and linear displacement (e.g., suspension travel) using appropriate magnet geometries. It does not activate stray-field immunity enhancements reserved for -100/-200 variants.
Is MLX90374GVS-ABC-300-RE qualified for automotive safety-critical systems?
Yes - MLX90374GVS-ABC-300-RE is certified to ISO26262 ASIL-C as a Safety Element out of Context (SEooC) and AEC-Q100 Grade 0. It includes built-in diagnostics (watchdogs, memory ECC, ADC monitoring) and failsafe output states, enabling its use in ASIL-B/C subsystems like electronic throttle control without additional hardware redundancy.
Can MLX90374GVS-ABC-300-RE operate from a 12 V battery supply without external regulation?
Yes - MLX90374GVS-ABC-300-RE supports direct 6–18 V battery supply operation. Internal regulation generates stable 3.3 V (VDEC) and 1.85 V (VDDD) rails. Overvoltage protection triggers at 21.5–24.5 V (PTC Entry Level VPROV1), and undervoltage lockout activates below 3.75–4.05 V (VDDUVL), ensuring reliable startup and shutdown in automotive electrical environments.
