Product details
Overview
MLX90371GVS-BCC-108-SP from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary position output with 12-bit resolution, ±0.5° angular accuracy in Rotary Stray-Field Immune Mode, and programmable ratiometric analog or PWM output. It operates from -40°C to +160°C in DMP-4 package and is used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90371GVS-BCC-108-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, pin-level design meaning, real-world application cards, and two validated alternative parts for ASIL-B-compliant non-contact position sensing designs.
Technical Context
The MLX90371GVS-BCC-108-SP implements Triaxis® Hall sensing with on-chip DSP, ADC, and NVRAM to decode absolute angle from 3-axis flux density (BX/BY/BZ). Its architecture supports 4/8-point linearization or 16/32-segment piecewise-linear transfer functions, enabling precise calibration against mechanical magnet motion.
This variant uses Rotary Stray-Field Immune Mode (BCC-108), optimized for low-field operation with 25 mT in-plane field tolerance and robustness against external magnetic interference. It features integrated reverse-polarity and overvoltage protection, 48-bit programmable ID, and ISO 26262 ASIL-B Safety Element out of Context compliance.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-108-SP?
The MLX90371GVS-BCC-108-SP is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range covers under-hood automotive locations including engine compartments and transmission housings. The device maintains specified angular accuracy and output stability across this full range due to on-chip temperature compensation algorithms implemented in its DSP firmware.
Does the MLX90371GVS-BCC-108-SP support both analog and PWM outputs simultaneously?
No, the MLX90371GVS-BCC-108-SP supports only one output mode at a time - either ratiometric analog voltage or PWM - selected during factory programming or end-user configuration via I²C. The BCC-108 variant is pre-configured for Rotary Stray-Field Immune Mode but retains full programmability of output type, transfer function, and diagnostic settings using Melexis' PTC software and compatible programming tools.
What package type does MLX90371GVS-BCC-108-SP use and how is it mounted?
The MLX90371GVS-BCC-108-SP uses the DMP-4 (Dual Mold Package) - a PCB-less, surface-mount module with four molded leads. It is designed for direct reflow soldering onto flexible or rigid printed circuit boards using STD4 2.54 mm lead pitch. No carrier substrate is required, and the package integrates decoupling capacitance internally, simplifying layout and reducing component count.
How does the MLX90371GVS-BCC-108-SP achieve stray magnetic field immunity?
The MLX90371GVS-BCC-108-SP achieves stray-field immunity through its proprietary Rotary Stray-Field Immune Mode (BCC-108), which combines Triaxis® 3-axis sensing with differential signal processing and dedicated algorithmic rejection of orthogonal magnetic interference. It is validated to reject fields up to ±1 T applied perpendicular to the sensitive axis, making it suitable for placement near high-current inverters, motors, or solenoids without shielding.
Is the MLX90371GVS-BCC-108-SP certified for functional safety applications?
Yes, the MLX90371GVS-BCC-108-SP is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC). It includes hardware-based diagnostics such as broken-wire detection on VDD/VSS, internal clock monitoring, memory ECC, and intelligent watchdog logic. These features are documented in the official Melexis Safety Manual and enable integration into ASIL-B automotive systems without requiring additional safety mechanisms at the ECU level.
