Product details
Overview
MLX90371GVS-BCC-301-RE from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute rotary or linear position output with 12-bit resolution and ±10-bit thermal accuracy. It operates from -40°C to +160°C, supports programmable ratiometric analog or PWM output, and implements stray-field immunity in Standard/Legacy mode for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90371GVS-BCC-301-RE datasheet, pinout, applications, or equivalent options, this device delivers ISO26262 ASIL-B safety element out-of-context compliance, user-programmable transfer characteristics (4/8-point LNR or 16/32-segment PWL), and robust operation in harsh under-hood environments with reverse polarity and overvoltage protection.
Technical Context
The MLX90371GVS-BCC-301-RE uses integrated IMC and on-chip DSP to decode absolute angular or linear position from magnet motion without mechanical contact. Its DMP-4 package integrates decoupling capacitance and features dual ground pins for EMC stability, while internal FIR filtering (configurable 1/11/1111 taps) and exponential moving average filters enable latency control from 440 μs to 5.1 ms.
This variant implements Standard/Legacy mode (BCC-301), providing backward compatibility with prior-generation MLX9036x devices and supporting fixed 0–360° rotary or 0–100% linear transfer functions. Output is configurable as ratiometric analog (0–100% VDD) or PWM (150–2000 Hz), with clamping and diagnostic bands programmable via NVRAM.

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-301-RE | Same DMP-4 package and pinout; adds 16-bit resolution and extended 0–200°C junction rating | Required for high-temp zones beyond 160°C ambient (e.g., near turbochargers) | Select when higher resolution or extended thermal margin is needed; firmware-compatible but requires reprogramming |
| MLX90363GDC-ABA-000-SP | SOIC-8 package; legacy Triaxis® device with fixed 10-bit resolution and no ASIL-B certification | Suitable only for non-safety-critical industrial position feedback where cost is primary constraint | Choose only for legacy redesigns with existing SOIC-8 footprint; lacks stray-field immunity and diagnostic coverage of MLX90371GVS-BCC-301-RE |
Compared with MLX90372GVS-BCC-301-RE, the MLX90371GVS-BCC-301-RE offers lower cost and sufficient resolution for most automotive pedal/throttle applications, while MLX90363GDC-ABA-000-SP provides pin-compatible migration path but requires external safety mechanisms to meet ASIL-B.
