Product details
Overview
MLX90371GVS-BCC-103-SP from Melexis is a Triaxis® monolithic position processor IC that measures all three magnetic field components (BX, BY, BZ) to deliver absolute rotary position output with 12-bit resolution and ±10° thermal accuracy over –40°C to +160°C. It operates in Rotary Stray-Field Immune Mode with DMP-4 package, supports programmable ratiometric analog or PWM output, and integrates on-chip DSP, NVRAM, and ISO 26262 ASIL-B safety elements for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-103-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin definitions for DMP-4, real-world accuracy specs under stray-field immunity, and direct alternative part comparisons for automotive position-sensing designs requiring functional safety compliance.
Technical Context
The MLX90371GVS-BCC-103-SP implements Triaxis® Hall sensing with integrated IMC to resolve 3D flux vectors, enabling robust absolute angle decoding without mechanical contact. Its on-chip DSP executes user-programmable piece-wise linear (up to 32-segment) transfer functions and configurable FIR/exponential filters to suppress noise and magnetic interference.
This variant uses the DMP-4 package with dual mold construction and no PCB substrate, features VDD/VSS/OUT/VSS pinout, and is factory-configured for Rotary Stray-Field Immune Mode (BCC-103), supporting 100 nF output capacitor and STD2 2.54 mm lead form per datasheet section 18.3.3.

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-103-SP | Same DMP-4 package and BCC-103 configuration but adds EEPROM-based lifetime logging and extended diagnostic coverage per ISO 26262 ASIL-B requirements. | Required where end-of-line calibration traceability or field failure root-cause analysis is mandated. | Select MLX90372GVS-BCC-103-SP if production requires certified diagnostic data logging beyond basic ASIL-B SEooC functionality. |
| TLV493DW2B6A1HTSA1 | Infineon 3D Hall sensor with I²C interface, 12-bit resolution, but no on-chip DSP, NVRAM, or ASIL-B certification; requires external microcontroller for linearization. | Suitable for cost-sensitive non-safety-critical applications where host MCU handles signal processing and diagnostics. | Choose TLV493DW2B6A1HTSA1 only when system architecture already includes a capable host processor and ASIL-B compliance is not required. |
Compared with MLX90371GVS-BCC-103-SP, MLX90372GVS-BCC-103-SP adds production-grade diagnostics and logging without changing pinout or firmware compatibility, while TLV493DW2B6A1HTSA1 reduces BOM count but shifts safety-critical processing to software-requiring full ASIL-B qualification of the host controller.

Yes, the MLX90371GVS-BCC-103-SP supports both ratiometric analog voltage output (0–100% VDD) and programmable PWM output (150–2000 Hz). Output mode is selected during programming via the MLX90371's NVRAM; no hardware change is needed. The MLX90371GVS-BCC-103-SP delivers identical accuracy and latency in both modes, with PWM duty cycle directly proportional to measured angle.
How does the Rotary Stray-Field Immune Mode (BCC-103) function in the MLX90371GVS-BCC-103-SP?
The MLX90371GVS-BCC-103-SP's BCC-103 configuration applies proprietary signal processing to reject external magnetic interference while preserving sensitivity to the target magnet's rotational field. It achieves this by exploiting orthogonal field component relationships and adaptive filtering-validated to maintain ±10° accuracy under ±1 T stray fields. This capability is factory-programmed and cannot be altered post-production.
Is the MLX90371GVS-BCC-103-SP certified to ISO 26262 ASIL-B?
Yes, the MLX90371GVS-BCC-103-SP is certified as a Safety Element out of Context (SEooC) for ASIL-B. Its safety mechanisms-including clock monitoring, memory ECC, supply voltage diagnostics, and intelligent watchdog-are fully documented in the official safety manual. The MLX90371GVS-BCC-103-SP enables reuse in ASIL-B systems without requalification when integrated per Melexis' safety guidelines.
What package type and pin configuration does the MLX90371GVS-BCC-103-SP use?
The MLX90371GVS-BCC-103-SP uses the DMP-4 (Dual Mold Package) with four terminals: VSS (Pin 1), VDD (Pin 2), OUT (Pin 3), and VSS (Pin 4). It has no PCB substrate and features STD2 2.54 mm lead form per datasheet section 18.3.3. This package enables direct soldering onto flex circuits or compact modules and provides superior thermal performance versus SOIC-8 or TSSOP-16 alternatives.
