Product details
Overview
MLX90371GVS-BCC-208-RE from Melexis is a Triaxis® absolute position sensor IC for linear displacement sensing in automotive and industrial applications, featuring stray-field immunity, 12-bit analog/PWM output, ±0.5° angular accuracy (typ.), and operation from −40°C to +160°C in DMP-4 package.
For engineers reviewing the MLX90371GVS-BCC-208-RE datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, magnetic field requirements for Linear Stray-Field Immune Mode, ISO26262 ASIL-B safety compliance, and real-world use cases including pedal and throttle position sensing.
Technical Context
The MLX90371GVS-BCC-208-RE implements Triaxis® Hall technology with on-chip DSP to resolve all three magnetic vector components (BX, BY, BZ) for robust absolute linear position decoding. Its programmable piecewise-linear transfer characteristic supports up to 32 segments, enabling precise calibration against mechanical nonlinearity.
This variant operates in Linear Stray-Field Immune Mode (BCC-208), requiring specific magnetic field gradients (≥1.5 mT/mm) and Z-component dominance (BZ ≥ 100 mT) while rejecting orthogonal interference. It integrates internal voltage regulation, reverse-polarity protection, and diagnostic features including broken-wire detection and clamped output levels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute linear position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-208-RE | Enhanced stray-field immunity with improved gradient sensitivity (≥1.0 mT/mm vs. ≥1.5 mT/mm) and extended diagnostic coverage per ISO26262 ASIL-B. | Targeted at next-gen ADAS actuators requiring tighter magnetic tolerance and higher diagnostic coverage metrics. | Preferred when upgrading legacy designs to meet updated OEM functional safety KPIs without changing mechanical layout. |
| TLE5012BE1500XUMA1 | Infineon's GMR-based angle sensor; offers 14-bit resolution but requires external magnet configuration for linear mode and lacks built-in stray-field immunity architecture. | Used in cost-sensitive industrial encoders where magnetic environment is controlled and ASIL-B certification is not required. | Consider only if existing design already uses GMR stack and can accommodate additional external filtering or shielding for stray fields. |
Compared with MLX90371GVS-BCC-208-RE, the MLX90372 variant provides tighter magnetic gradient tolerance and expanded diagnostic scope for evolving ASIL-B targets, while the TLE5012B demands external magnetic optimization and lacks native stray-field resilience - making MLX90371GVS-BCC-208-RE the optimal choice for ruggedized linear position sensing in uncontrolled magnetic environments.

FAQ
What magnetic field configuration is required for MLX90371GVS-BCC-208-RE in Linear Stray-Field Immune Mode?
The MLX90371GVS-BCC-208-RE requires a dominant vertical magnetic field component (BZ ≥ 100 mT) with a minimum in-plane gradient of ≥1.5 mT/mm to ensure accurate linear position decoding. This configuration enables rejection of orthogonal stray fields from adjacent actuators while maintaining ≤±0.5° angular error across −40°C to +160°C. The DMP-4 package's sensitive spot positioning must align precisely with the magnet's travel path per section 18.3.6 of the datasheet.
Does MLX90371GVS-BCC-208-RE support both analog and PWM outputs simultaneously?
No, the MLX90371GVS-BCC-208-RE supports either ratiometric analog output or PWM output - selected during end-user programming via the I²C interface. Both modes share the same OUT pin (Pin 3) and cannot operate concurrently. The analog mode delivers 0–100% VDD output with 12-bit resolution and 200 V/ms slew rate (no load), while PWM mode provides 150–2000 Hz frequency with ±5% tolerance and configurable duty cycle.
How is functional safety implemented in MLX90371GVS-BCC-208-RE for ASIL-B compliance?
The MLX90371GVS-BCC-208-RE achieves ISO26262 ASIL-B Safety Element out of Context (SEooC) status through integrated hardware safety mechanisms: memory ECC for NVRAM/ROM, lockstep-capable DSP core with watchdog timers (IWD/AWD), periodic self-tests of ADC and signal chain, and diagnostic coverage for supply, ground, and output faults. These features are documented in the official Safety Manual (Rev. 004, section 14) and require no external components to satisfy ASIL-B element-level requirements.
Can MLX90371GVS-BCC-208-RE be reprogrammed in-system after soldering?
Yes, the MLX90371GVS-BCC-208-RE supports full in-system programming via its I²C interface, including configuration of output mode (analog/PWM), transfer characteristic (4/8/17/32-point PWL), clamping levels, diagnostic thresholds, and magnetic sensing parameters. Reprogramming requires only VDD, VSS, SDA, and SCL connections - no test pins or special voltage sequences. All settings are stored in on-chip NVRAM and persist through power cycles.
What is the purpose of the dual VSS pins (1 and 4) in the DMP-4 package of MLX90371GVS-BCC-208-RE?
The dual VSS pins (1 and 4) in the DMP-4 package of MLX90371GVS-BCC-208-RE provide separate low-impedance return paths for analog and digital ground domains, reducing noise coupling between the Triaxis® front-end and DSP/output stages. This separation improves measurement stability in high-EMI environments and enhances thermal dissipation during sustained 12 mA supply current operation - critical for maintaining 10-bit thermal accuracy over the full −40°C to +160°C range.
