Product details
Overview
MLX90371GVS-BCC-300-RE from Melexis is a Triaxis® monolithic position processor IC that measures all three orthogonal 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 immune operation in Standard/Legacy Mode for throttle and pedal position sensing in automotive powertrain systems.
For engineers reviewing the MLX90371GVS-BCC-300-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed pin functions (VDD/VSS/OUT), real-world timing specs (462 µs latency), ISO26262 ASIL-B safety qualification, and two validated alternative parts for legacy-mode position sensing designs.
Technical Context
The MLX90371GVS-BCC-300-RE uses integrated IMC-based Triaxis® sensing with on-chip DSP to compute absolute angle or displacement from raw B-field vector data. Its DMP-4 package embeds decoupling capacitance and enables direct PCB-less mounting in space-constrained automotive modules.
This variant operates in Standard/Legacy Mode (BCC-300), delivering backward compatibility with prior-generation MLX9036x sensors. It supports user-programmable 4-/8-point linearization or 16-/32-segment piecewise-linear transfer characteristics via NVRAM, with configurable diagnostic thresholds and clamping levels.
Key Specifications

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-300-RE?
The MLX90371GVS-BCC-300-RE is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range covers under-hood environments in gasoline, diesel, and hybrid powertrains where ambient temperatures exceed 125°C. The device maintains specified accuracy and latency performance across this full range without derating.
Does the MLX90371GVS-BCC-300-RE support both analog and PWM output modes?
Yes, the MLX90371GVS-BCC-300-RE supports selectable ratiometric analog output (0–100% VDD) or programmable PWM output (150–2000 Hz). Output mode is configured via on-chip NVRAM during programming; no external components are required to switch between modes. The DMP-4 package integrates internal decoupling to ensure stable output switching.
How does the MLX90371GVS-BCC-300-RE achieve stray-field immunity in Standard/Legacy Mode?
In Standard/Legacy Mode (BCC-300), the MLX90371GVS-BCC-300-RE applies calibrated offset compensation and differential signal processing to reject uniform external magnetic fields up to ±1 T. This is achieved through factory-trimmed sensor front-end parameters and on-chip DSP algorithms-not hardware shielding-making it effective against EMI from nearby motors or solenoids without added cost or size.
What package type is used for the MLX90371GVS-BCC-300-RE and what are its key mechanical features?
The MLX90371GVS-BCC-300-RE uses the DMP-4 (Dual Mold Package), a 4-pin, PCB-less surface-mount package with molded-in 100 nF decoupling capacitor and straight leads (STD0 configuration). Its 3.2 × 2.5 mm footprint and 0.55 mm profile enable direct mounting on flex circuits or metal substrates in tight spaces such as throttle bodies and brake calipers.
Is the MLX90371GVS-BCC-300-RE certified for functional safety applications?
Yes, the MLX90371GVS-BCC-300-RE is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC). It includes on-chip diagnostics (broken-wire detection, supply monitoring, watchdog timers), failure modes analysis documentation, and a safety manual-enabling integration into ASIL-B systems like engine control units without requiring additional hardware-level safety mechanisms.
