Product details
Overview
MLX90374GVS-ABB-300-RX 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 angular/linear configurations. It is deployed in automotive throttle and steering wheel position sensing systems.
For engineers reviewing the MLX90374GVS-ABB-300-RX datasheet, pinout, applications, or equivalent options, key selection considerations include DMP-4 package compatibility, SENT protocol compliance (SAE J2716 APR2016), dual-output redundancy, temperature range (-40°C to +160°C), and legacy-mode (-300) magnetic configuration support.
Technical Context
The MLX90374GVS-ABB-300-RX 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 architecture enables absolute position extraction from moving magnets without mechanical contact.
In legacy mode (-300 option code), it supports both angular rotary and linear displacement measurement with configurable piecewise linear (PWL) transfer characteristics (up to 32 points). Output modes include SENT with error codes and user-defined values, plus a dedicated programmable switch function - not PWM-only or dual-PWM.

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-300-RX | ABC revision replaces ABB with enhanced diagnostics, safe startup sequence (TSafeStup = 11.2 ms), and full feature set per datasheet Rev 4 | Same legacy (-300) magnetic configuration and DMP-4 package - suitable for new designs requiring latest reliability features | Select ABC-300 for new designs; ABB-300 remains production-supported but lacks safe startup and updated diagnostics |
| MLX90363GDC-ABB-300-RE | SOIC-8 package (not DMP-4), dual PWM output only (no SENT), same -300 legacy mode and temperature rating | Requires PCB layout with SOIC footprint and external pull-ups; limited to PWM-only host interfaces without SENT decode capability | Choose only if existing SOIC-8 layout and PWM-only interface constrain redesign; sacrifices SENT diagnostics and compact DMP form factor |
Compared with MLX90374GVS-ABB-300-RX, the ABC-300 variant adds verified safe startup and expanded diagnostics while retaining identical pinout and functionality - making it a drop-in upgrade. The SOIC-8 MLX90363 alternative trades SENT capability and DMP-4 size for legacy PCB compatibility and dual-PWM simplicity.

FAQ
What is the primary output interface supported by the MLX90374GVS-ABB-300-RX?
The MLX90374GVS-ABB-300-RX supports SENT (SAE J2716 APR2016) on OUT1 and a programmable switch function on OUT2. It does not support dual-PWM output in the ABB-300 configuration - that mode is reserved for other option codes like ABB-200. SENT output includes CRC, error codes, and user-defined payload fields for robust diagnostics.
Is the MLX90374GVS-ABB-300-RX pin-compatible with the ABC revision?
Yes, the MLX90374GVS-ABB-300-RX is pin-compatible with MLX90374GVS-ABC-300-RX - both use the identical DMP-4 package with the same 4-pin layout (OUT1, VSS, VDD, OUT2). No PCB changes are required when upgrading from ABB to ABC, though firmware may need updates to leverage new diagnostics features.
What magnetic configuration does the "-300" option code specify for the MLX90374GVS-ABB-300-RX?
The "-300" option code designates Legacy / Angular Rotary / Linear position mode - a standardized configuration supporting both rotary (0–360°) and linear displacement measurement with built-in stray-field immunity. It uses the same magnetic circuit design as Melexis' earlier MLX90363, enabling drop-in replacement in many legacy systems.
Does the MLX90374GVS-ABB-300-RX support AEC-Q100 qualification and ISO26262 ASIL-C?
Yes, the MLX90374GVS-ABB-300-RX is AEC-Q100 qualified (Grade 0, −40°C to +160°C) and certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC). This means it provides documented safety mechanisms - including watchdogs, memory ECC, and diagnostic coverage - intended for integration into ASIL-C automotive systems.
What is the supply voltage range and current consumption of the MLX90374GVS-ABB-300-RX?
The MLX90374GVS-ABB-300-RX operates from 4.5 V to 5.5 V in regulated mode (typical supply current: 9.0 mA), or 6 V to 18 V in battery mode (typical supply current: 8.0 mA). Under-voltage lockout triggers at 3.90 V, and overvoltage protection activates at 7.35 V (5 V mode) or 23.0 V (battery mode).
