Product details
Overview
MLX90371GVS-BCC-100-RE 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, ±10° angular accuracy over -40°C to +160°C, and stray-field immunity in rotary mode. It operates from 4.5–5.5 V, draws 6–10 mA, and supports programmable ratiometric analog or PWM output for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-100-RE datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DMP-4 package terminal mapping, ISO26262 ASIL-B safety context, real-world use cases, and validated alternative options for high-reliability position sensing designs.
Technical Context
The MLX90371GVS-BCC-100-RE implements on-chip DSP-based signal processing of triaxial Hall sensor data to compute absolute angle from magnet motion, using a 12-bit ADC and firmware-configurable FIR or exponential moving average filtering. Its architecture includes integrated voltage regulation, reverse-polarity and overvoltage protection, and dual-ground (VSS) terminals for noise immunity.
This variant is factory-programmed for Rotary Stray-Field Immune Mode – Low-Field Variant (BCC-100), requiring ≤25 mT in-plane flux (BX/BY) and ≥100 mT axial flux (BZ), with programmable 4-/8-point linearization or 16-/32-segment piecewise-linear transfer characteristics and user-defined discontinuity point (zero-degree reference).

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-100-RE | Same DMP-4 package and BCC-100 mode, but adds 16-bit resolution and extended diagnostic coverage per ISO26262 ASIL-C readiness. | Targeted for next-gen ADAS and steer-by-wire where higher resolution and deeper diagnostics are required. | Select when system-level ASIL-C decomposition mandates enhanced fault coverage beyond ASIL-B. |
| TLV493DW2B6HTSA1 | Infineon 3D Hall sensor with I²C interface; no on-chip DSP, requires external MCU for angle computation; 12-bit output, ±1.5° typical accuracy. | Used in cost-sensitive, non-safety-critical applications where host processor handles linearization and diagnostics. | Choose when design already includes capable MCU and lower BOM cost outweighs integrated processing and ASIL-B certification. |
Compared with MLX90371GVS-BCC-100-RE, the MLX90372 offers higher resolution and ASIL-C readiness at increased cost and complexity, while the TLV493DW2B6HTSA1 shifts signal processing to the host MCU and lacks built-in safety mechanisms-making the MLX90371GVS-BCC-100-RE optimal for drop-in, certified, single-chip rotary position solutions.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-100-RE?
The MLX90371GVS-BCC-100-RE is qualified for continuous operation from -40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. Its internal thermal compensation ensures ±10° angular accuracy across this full range, making it suitable for under-hood and transmission-mounted applications where extreme thermal cycling occurs.
Does the MLX90371GVS-BCC-100-RE require external programming hardware?
Yes, the MLX90371GVS-BCC-100-RE requires Melexis' PTC-04 programmer and GUI software for initial configuration of output mode (analog/PWM), transfer characteristic (4/8-point LNR or 16/32-segment PWL), zero-point alignment, and diagnostic settings. The device retains all programmed parameters in on-chip NVRAM after power cycle.
What magnetic field strength is required for proper operation of the MLX90371GVS-BCC-100-RE?
The MLX90371GVS-BCC-100-RE in Rotary Stray-Field Immune Mode (BCC-100) requires ≤25 mT in-plane flux (BX/BY) and ≥100 mT axial flux (BZ). This low-field configuration enables use with small, cost-effective magnets while maintaining immunity to external stray fields from nearby actuators or wiring.
Can the MLX90371GVS-BCC-100-RE be used in linear position sensing applications?
Yes-the MLX90371GVS-BCC-100-RE can be configured for linear displacement sensing by pairing it with a linear magnet track and selecting appropriate transfer characteristics. However, its BCC-100 option is optimized for rotary geometry; for dedicated linear use, BCC-200 variants are recommended due to tailored magnetic sensitivity and filtering.
Is the MLX90371GVS-BCC-100-RE pin-compatible with other MLX90371 package variants?
No-the MLX90371GVS-BCC-100-RE uses the DMP-4 package with 4 terminals (VSS, VDD, OUT, VSS), while SOIC-8 and TSSOP-16 variants have different pin counts, layouts, and grounding schemes. Direct PCB replacement is not possible; layout redesign is required when switching packages.
