Product details
Overview
MLX90371GVS-BCC-208-SP from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary or linear position output with 12-bit resolution, ±10-bit thermal accuracy, and programmable stray-field immune linear mode (BCC-208). It operates from -40°C to +160°C in automotive throttle, pedal, and ride height sensing applications.
For engineers reviewing the MLX90371GVS-BCC-208-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed pin functions, real-world timing specs (462 µs latency), functional safety compliance (ISO 26262 ASIL-B SEooC), and validated alternatives for linear-stray-immune position sensing.
Technical Context
The MLX90371GVS-BCC-208-SP implements on-chip DSP-based signal processing of triaxial Hall sensor data to compute absolute angular or linear position without external microcontroller intervention. Its architecture includes a 12-bit ADC, FIR/EMA filtering, and programmable piecewise-linear transfer characteristic (up to 32 segments) tailored for BCC-208's Linear Stray-Field Immune Mode.
It supports dual-output configuration: ratiometric analog (0–100% VDD) or PWM (150–2000 Hz), both with clamping and diagnostic features. The DMP-4 package integrates decoupling capacitance and uses only four terminals-VSS, VDD, OUT, and VSS-with internal regulator and reverse-polarity protection.

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-208-SP | Same DMP-4 package and BCC-208 configuration but adds EEPROM-based user-programmable ID and extended diagnostic coverage | Required where traceability, calibration history, or enhanced fault logging is mandated in Tier-1 production | Select MLX90372GVS-BCC-208-SP if firmware-upgradable diagnostics or 48-bit unique ID registration is needed for vehicle-level audit trails |
| TLV493DW2B6A1HALR | 3-axis Hall sensor with I²C interface only; no integrated DSP, PWM, or analog output; requires external MCU for position calculation | Suitable for cost-sensitive designs with existing host processors and flexible software-defined calibration | Choose TLV493DW2B6A1HALR only when system already includes capable MCU and can absorb latency from external computation |
Compared with MLX90371GVS-BCC-208-SP, MLX90372GVS-BCC-208-SP adds field-programmable memory and deeper diagnostics at identical pinout and performance, while TLV493DW2B6A1HALR shifts signal processing burden to host firmware and lacks ASIL-B qualification or stray-field immunity tuning.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-208-SP?
The MLX90371GVS-BCC-208-SP 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 without thermal derating. The device maintains ±10-bit thermal accuracy across this full span, verified per Melexis datasheet revision 004, page 13.
Does the MLX90371GVS-BCC-208-SP require external decoupling capacitors?
No, the MLX90371GVS-BCC-208-SP does not require external decoupling capacitors because its DMP-4 package integrates a 100 nF capacitor internally (per BCC-208 option code definition). This eliminates PCB space, reduces bill-of-materials count, and improves reliability by removing solder joints associated with discrete capacitors.
How is stray-field immunity implemented in the MLX90371GVS-BCC-208-SP?
The MLX90371GVS-BCC-208-SP achieves stray-field immunity through factory-programmed signal processing optimized for linear motion configurations (BCC-208 = Linear Stray-Field Immune Mode). It uses differential triaxial sensing and adaptive filtering to reject orthogonal magnetic interference up to ±1 T, as defined in section 8.3 of the datasheet.
Can the MLX90371GVS-BCC-208-SP output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-208-SP supports either ratiometric analog or PWM output-not both concurrently. Output mode is selected during end-user programming via the NVRAM configuration (section 13.1.1). Switching between modes requires reprogramming; no hardware change or pin reconfiguration is needed.
Is the MLX90371GVS-BCC-208-SP certified for functional safety applications?
Yes, the MLX90371GVS-BCC-208-SP is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC), with documented safety mechanisms including memory ECC, voltage monitoring, watchdog timers, and diagnostic output signaling. Full safety manual documentation is provided by Melexis for integration into ASIL-B systems.
