Product details
Overview
MLX90374GDC-ABB-200-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute linear position sensing with stray-field immunity. It delivers dual PWM output, operates from -40°C to +160°C, consumes 9.0–12.6 mA, and is AEC-Q100 qualified for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90374GDC-ABB-200-RE datasheet, pinout, applications, or equivalent options, key selection factors include its SOIC-8 package, linear stray-field immune configuration (-200 option code), dual-output redundancy, ISO26262 ASIL-C safety compliance, and SENT/PWM protocol flexibility.
Technical Context
The MLX90374GDC-ABB-200-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/position decoding. Its linear stray-field immune mode (option -200) enables robust operation in magnetically noisy environments without external shielding.
It supports dual-output configurations: either two independent PWM channels or SENT plus programmable switch output. The device features on-chip diagnostics including intelligent and absolute watchdogs, configurable filtering (FIR11/FIR1111), and fail-safe state duration of 9.8–34.6 ms depending on revision.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90374GDC-ABC-200-RE | ABC revision replaces ABB; adds enhanced diagnostics, safe startup sequence, and improved temperature stability | Same linear stray-field immune function and SOIC-8 package; preferred for new designs per Melexis documentation | Select ABC-200 for production programs requiring latest reliability and functional safety features |
| MLX90375GDC-ABB-200-RE | Successor IC with extended temperature range (–40°C to +175°C), lower current (7.5–9.5 mA), and updated SENT timing | Pin-compatible replacement with identical -200 linear stray-field configuration; supports higher ambient thermal environments | Choose MLX90375GDC-ABB-200-RE when operating above 160°C or requiring reduced power consumption |
Compared with MLX90374GDC-ABB-200-RE, the ABC-200 variant improves diagnostic coverage and startup safety, while the MLX90375GDC-ABB-200-RE extends thermal capability and lowers supply current-both retain identical linear position functionality and SOIC-8 footprint for seamless migration paths.

FAQ
What is the primary sensing architecture used in the MLX90374GDC-ABB-200-RE?
The MLX90374GDC-ABB-200-RE employs Melexis' proprietary Triaxis® Hall technology, which simultaneously measures all three orthogonal components (Bx, By, Bz) of the applied magnetic flux density. This enables robust absolute position decoding from a single moving magnet in either rotary or linear configurations-specifically configured here for linear stray-field immune operation per the -200 option code.
Does the MLX90374GDC-ABB-200-RE support both PWM and SENT outputs simultaneously?
No-the MLX90374GDC-ABB-200-RE supports dual-output operation in two mutually exclusive modes: either dual PWM outputs or one SENT output plus one programmable switch output. The output mode is configured during programming and cannot be dynamically switched in runtime; SENT mode also disables the second PWM channel.
What does the "-200" option code signify for the MLX90374GDC-ABB-200-RE?
The "-200" option code indicates linear position sensing with stray-field immunity-a hardware and firmware configuration optimized to reject interference from external magnetic sources such as nearby motors or solenoids. This mode is validated for linear displacement applications and differs from -100 (angular stray-field immune) and -300 (legacy angular/linear) variants.
Is the MLX90374GDC-ABB-200-RE pin-compatible with the ABC revision?
Yes-MLX90374GDC-ABB-200-RE and MLX90374GDC-ABC-200-RE share identical SOIC-8 pinout, electrical interface, and mechanical footprint. However, the ABC revision introduces enhanced diagnostics, safe startup behavior, and improved thermal drift performance; Melexis explicitly states ABC is preferred for new designs.
What safety certifications apply to the MLX90374GDC-ABB-200-RE?
The MLX90374GDC-ABB-200-RE is certified to AEC-Q100 Grade 0 and classified as an ISO26262 ASIL-C Safety Element out of Context (SEooC). It includes integrated safety mechanisms such as dual watchdog timers, memory ECC, and configurable diagnostic cycles-but final system-level ASIL compliance requires integration into a compliant safety architecture by the end user.
