Product details
Overview
MLX90374GVS-ABB-200-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute linear position sensing in stray-field-immune configurations. It delivers dual PWM or SENT + programmable switch outputs, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, and supports 4–32-point piecewise linear transfer characteristic programming. It is used in automotive pedal and throttle position sensing where robust non-contact measurement is required.
For engineers reviewing the MLX90374GVS-ABB-200-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed output modes (dual PWM / SENT+switch), validated timing specs (e.g., Tstup ≤ 8.6 ms in PWM), functional safety context (ASIL-C SEooC), and real-world linear position use cases with stray-field immunity.
Technical Context
The MLX90374GVS-ABB-200-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz components, an analog signal conditioner, a DSP for advanced angle/position decoding, and a dual-output driver stage. Its architecture enables absolute linear position measurement using magnet movement parallel to the IC surface, with built-in stray-field immunity optimized for the -200 option code.
This variant implements continuous asynchronous acquisition mode (TangleMeas = 528–588 µs), supports SENT SAE J2716 APR2016 with 3 µs tick time, and delivers dual digital outputs-either two independent PWM channels or SENT plus a programmable open-drain switch-with configurable diagnostics and error reporting per channel.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90374GVS-ABC-200-RE | ABC revision adds safe startup sequence (TSafeStup = 11.2 ms), enhanced diagnostics, and full feature set vs ABB's legacy support only. | Required for new designs targeting full ASIL-C compliance; ABB lacks COLD_SAFE_STARTUP_EN and updated memory ECC. | Select ABC-200 for production designs; ABB-200 is maintained for legacy continuity only. |
| MLX90363GSE-AAA-000-SP | Single-output SENT-only variant in SOIC-8; no PWM capability, no programmable switch, lower accuracy (±0.5°), no ASIL-C certification. | Suitable for cost-sensitive non-safety-critical applications like HVAC flap control; lacks redundancy and stray-field hardening. | Use only when dual output, ASIL-C, or linear stray-field immunity are not required. |
Compared with MLX90374GVS-ABB-200-RE, the ABC-200 offers verified safe startup and expanded diagnostics essential for new ASIL-C systems, while the MLX90363 provides lower-cost single-output functionality at the expense of safety certification and magnetic robustness.

The MLX90374GVS-ABB-200-RE operates from -40°C to +160°C ambient temperature, validated per AEC-Q100 Grade 0 qualification. This range supports direct placement in engine compartments, transmission housings, and other high-thermal-stress zones without external cooling or shielding. The DMP-4 package's thermal resistance (RθJA ≈ 120°C/W) ensures junction temperature remains within safe limits under typical 10.5 mA supply current conditions.
Does the MLX90374GVS-ABB-200-RE support SENT protocol, and which version?
Yes, the MLX90374GVS-ABB-200-RE supports SAE J2716 APR2016 SENT protocol in both synchronous (with pause) and asynchronous modes. It delivers 12-bit position data with CRC, status flags, and user-defined fields in standard 3 µs tick time configuration. Frame lengths are programmable (282–320 ticks), and it supports Fast SENT (1.5 µs) and Slow SENT (6 µs) variants depending on system timing constraints.
What package type does the MLX90374GVS-ABB-200-RE use, and what are its key mechanical features?
The MLX90374GVS-ABB-200-RE uses the DMP-4 (Dual Mold Package) - a PCB-less, 4-terminal surface-mount package with straight leads (STD3 2.00 form). It measures 3.5 × 3.5 × 1.0 mm, features integrated decoupling capacitance (C1/C4 = 10 nF), and is optimized for direct magnet coupling and high-vibration reliability. Lead finish is matte Sn, RoHS-compliant.
Is the MLX90374GVS-ABB-200-RE certified for functional safety applications?
Yes, the MLX90374GVS-ABB-200-RE is qualified as an ISO26262 ASIL-C Safety Element out of Context (SEooC). It includes hardware-level safety mechanisms such as dual-core lockstep monitoring, memory ECC, voltage/temperature watchdogs, and diagnostic coverage for magnetic front-end and DSP paths. A dedicated safety manual (document 3901090374 Rev 4) details FMEDA results and integration guidance.
How is linear position measured with the MLX90374GVS-ABB-200-RE, and what magnetic configuration is required?
The MLX90374GVS-ABB-200-RE measures linear position using a moving magnet oriented perpendicular to the IC surface, with motion parallel to the X-axis. The -200 option code configures internal signal processing for stray-field immune linear mode, requiring a specific magnetic circuit (e.g., back-biased magnet with IMC) detailed in Melexis Application Note AN-102. Accuracy is ±0.3° typical INL over full stroke.
