Product details
Overview
MLX90371GVS-BCC-258-RE from Melexis is a Triaxis® absolute position sensor IC for linear displacement sensing in automotive and industrial applications. It delivers 12-bit analog or PWM output, supports stray-field immune operation, achieves ±1.5° angular accuracy (typ.) in Linear Stray-Field Immune Mode, and operates across –40°C to +160°C with 4.5–5.5 V supply.
For engineers reviewing the MLX90371GVS-BCC-258-RE datasheet, pinout, applications, or equivalent options, this device offers programmable transfer characteristics, ISO26262 ASIL-B safety compliance, on-chip DSP processing, and DMP-4 package integration for compact PCB-less mounting in throttle, pedal, and ride-height systems.
Technical Context
The MLX90371GVS-BCC-258-RE implements Triaxis® Hall technology to measure all three magnetic field components (BX, BY, BZ) simultaneously, enabling robust absolute linear position decoding without mechanical contact. Its integrated DSP performs real-time coordinate transformation and piecewise-linear interpolation using up to 32 segments.
This variant is configured specifically for Linear Stray-Field Immune Mode (BCC-2xx), featuring factory-trimmed gain calibration, programmable FIR filtering (FIR1/FIR11/FIR1111), and dual-ground architecture optimized for EMC resilience in high-noise environments such as engine compartments.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-258-RE?
The MLX90371GVS-BCC-258-RE operates from –40°C to +160°C, fully qualified per AEC-Q100 Grade 0 standards. This range enables direct mounting in engine bays, transmission housings, and brake calipers without external thermal shielding. The MLX90371GVS-BCC-258-RE maintains specified accuracy and latency performance across this full span, with internal temperature compensation applied to both magnetic front-end and output stages.
How does the MLX90371GVS-BCC-258-RE achieve stray-field immunity in linear mode?
The MLX90371GVS-BCC-258-RE achieves stray-field immunity through dedicated BCC-258 configuration firmware, differential Triaxis® sensing topology, and on-chip digital filtering tuned to reject orthogonal magnetic interference ≥10 mT. This is validated per ISO11452-8 test methods and documented in Section 8.3 of the datasheet. The MLX90371GVS-BCC-258-RE's immunity is factory-programmed and does not require user calibration.
Can the MLX90371GVS-BCC-258-RE output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-258-RE supports either ratiometric analog or PWM output-not both concurrently. Output mode is selected during programming via Melexis' PTC software and stored in NVRAM. Switching requires reprogramming; the MLX90371GVS-BCC-258-RE does not support dynamic runtime mode switching. Analog mode offers 12-bit resolution with 10-bit thermal accuracy; PWM mode provides 12-bit effective resolution at 150–2000 Hz.
What package type and lead configuration does the MLX90371GVS-BCC-258-RE use?
The MLX90371GVS-BCC-258-RE uses the DMP-4 (Dual Mold Package) with STD4 2.54 mm pitch trim-and-form leads, as defined in Section 18.3.4 of the datasheet. This PCB-less package integrates decoupling capacitance and requires no external VDEC capacitor. The MLX90371GVS-BCC-258-RE's four-terminal layout (VSS–VDD–OUT–VSS) simplifies routing and enhances thermal dissipation in confined spaces.
Is the MLX90371GVS-BCC-258-RE certified to ISO26262 ASIL-B?
Yes, the MLX90371GVS-BCC-258-RE is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC), with documented safety mechanisms including memory ECC, clock monitoring, supply voltage supervision, and diagnostic output signaling. This certification applies to the entire MLX90371 family, including the BCC-258 variant, and is covered in Section 14 of the datasheet. The MLX90371GVS-BCC-258-RE requires integration into a larger system to achieve end-application ASIL-B compliance.
