Product details
Overview
MLX90374GVS-ABC-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 or dual PWM signals, operates from -40°C to +160°C, supports stray-field immune configurations, and is AEC-Q100 qualified for automotive throttle, pedal, and steering wheel position sensing.
For engineers reviewing the MLX90374GVS-ABC-300-RX datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed output modes (SENT + switch), functional safety compliance (ISO 26262 ASIL-C SEooC), accuracy specs per -300 legacy mode, and validated alternative part options.
Technical Context
The MLX90374GVS-ABC-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 measurement without mechanical contact using rotating or linear magnets.
This ABC revision supports programmable transfer characteristics (4/8/16/32-point PWL), dual-output redundancy (PWM/PWM or SENT/switch), and configurable diagnostics including intelligent and absolute watchdogs with 20 ms timeout. It operates in legacy mode (-300 option code) with standard angular/linear position decoding and no stray-field immunity enhancement.

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-RX | Higher-resolution 14-bit output, extended SENT frame support (up to 40 bits), improved INL (<±0.5°), same DMP-4 package and pinout. | Targeted at next-gen ADAS and steer-by-wire where tighter angular accuracy and richer diagnostics are required. | Select MLX90375GVS-ABC-300-RX when >12-bit resolution and enhanced CRC coverage are mandatory; otherwise MLX90374GVS-ABC-300-RX remains optimal for cost-sensitive ASIL-B systems. |
| TLV493DW2B6H1XTMA1 | 3-axis Hall sensor with I²C interface only; no SENT/PWM outputs; lower temperature grade (-40°C to +125°C); SOIC-8 package. | Suitable for non-safety-critical industrial encoders or consumer robotics where serial bus integration is preferred over analog/digital dual outputs. | Choose TLV493DW2B6H1XTMA1 only for I²C-based designs requiring minimal footprint and lower ambient temperature operation; not drop-in compatible due to interface and qualification differences. |
Compared with MLX90374GVS-ABC-300-RX, MLX90375GVS-ABC-300-RX offers higher accuracy and extended diagnostics but at increased cost, while TLV493DW2B6H1XTMA1 provides I²C simplicity but lacks automotive qualification, dual outputs, and high-temp capability - making MLX90374GVS-ABC-300-RX the balanced choice for production-grade throttle/pedal systems.

In its -300 legacy configuration, it delivers 12-bit angle data plus status flags in standard 4-nibble SENT frames with configurable pause timing.
What output configurations are supported by the MLX90374GVS-ABC-300-RX?
The MLX90374GVS-ABC-300-RX supports two primary output modes: (1) SENT on OUT1 with programmable switch on OUT2, or (2) dual PWM on both outputs. Configuration is performed via end-user programmable registers; no hardware changes are needed to switch between modes. Both outputs operate independently with separate diagnostics and timing controls.
Is the MLX90374GVS-ABC-300-RX pin-compatible with other MLX90374 variants in DMP-4 package?
Yes, all MLX90374 variants in DMP-4 package-including MLX90374GVS-ABC-100-RX, MLX90374GVS-ABC-200-RX, and MLX90374GVS-ABC-300-RX-share identical 4-pin DMP-4 pinout (OUT1, VSS, VDD, OUT2), mechanical dimensions, and solder footprint. Only internal calibration and firmware settings differ between option codes.
How does the MLX90374GVS-ABC-300-RX achieve functional safety compliance for ASIL-C systems?
The MLX90374GVS-ABC-300-RX is certified as an ISO 26262 ASIL-C Safety Element out of Context (SEooC), meaning it provides documented safety mechanisms-including dual watchdogs (IWD/AWD), memory ECC, analog path monitoring, and CRC-protected SENT frames-that can be integrated into higher-level ASIL-B or ASIL-C systems when combined with appropriate system-level safety measures defined by the end user.
