Product details
Overview
MLX90371GVS-BCC-353-RE from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary or linear position output with 12-bit resolution, ±10-bit thermal accuracy, and programmable analog or PWM output. It operates from -40°C to +160°C in DMP-4 package and supports ISO26262 ASIL-B safety compliance for automotive pedal, throttle, and steering applications.
For engineers reviewing the MLX90371GVS-BCC-353-RE datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, DMP-4 terminal mapping, stray-field-immune legacy-mode behavior, and direct alternatives for position-sensing system design and qualification.
Technical Context
The MLX90371GVS-BCC-353-RE implements on-chip DSP-based signal processing of triaxial Hall sensor data to compute absolute angular or linear position without external microcontroller intervention. Its architecture includes integrated ADC, FIR/EMA filtering, programmable transfer characteristic (4/8-point LNR or 16/32-segment PWL), and dual-path output stage supporting ratiometric analog or 150–2000 Hz PWM.
This variant uses Standard/Legacy Mode (BCC-353) with DMP-4 packaging, enabling PCB-less mounting and built-in decoupling. It features reverse-polarity and overvoltage protection, active/passive diagnostics (broken-wire detection), and 48-bit user-programmable ID for traceability in safety-critical systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-353-RE | Same DMP-4 package and BCC-353 mode, but adds EEPROM-based self-test and enhanced diagnostic coverage | Required where ISO26262 ASIL-B requires higher diagnostic coverage than SEooC baseline | Select when functional safety audit demands extended diagnostic capability beyond MLX90371GVS-BCC-353-RE's SEooC certification |
| MLX90363GDC-ABB-100-RE | SOIC-8 package, Rotary Stray-Field Immune Mode (BCC-100), 10-bit resolution, no ASIL-B certification | Suitable for cost-sensitive non-safety applications such as HVAC damper control or industrial actuation | Choose for legacy designs needing SOIC-8 footprint compatibility and lower resolution tolerance, without safety certification overhead |
Compared with MLX90371GVS-BCC-353-RE, MLX90372GVS-BCC-353-RE extends diagnostics for higher ASIL-B coverage, while MLX90363GDC-ABB-100-RE trades safety and resolution for SOIC-8 compatibility and cost-neither is pin-compatible, but both serve adjacent position-sensing use cases.
