Product details
Overview
MLX90371GVS-BCC-200-RE from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute linear position output with 12-bit resolution, ±10° thermal accuracy over −40°C to +160°C, and stray-field immunity in Linear Stray-Field Immune Mode. It serves as a contactless replacement for potentiometers in automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-200-RE datasheet, pinout, applications, or equivalent options, this page provides verified pin definitions for DMP-4 package, confirmed analog/PWM output modes, ISO26262 ASIL-B safety compliance, programmable transfer characteristics, and real-world linear position use cases.
Technical Context
The MLX90371GVS-BCC-200-RE implements Triaxis® Hall technology with on-chip DSP, ADC, and NVRAM to decode absolute linear displacement from magnet motion using integrated magnetic concentrators. Its architecture includes dual-stage filtering (FIR and exponential moving average), programmable clamping, and diagnostic functions including broken-wire detection.
This variant operates exclusively in Linear Stray-Field Immune Mode (BCC-200), requiring specific magnetic field configurations per section 8.3 of the datasheet: BZ ≥ 100 mT, |BX| ≤ 25 mT, |BY| ≤ 25 mT, with defined in-plane gradients. Output latency is 440–462 μs and step response reaches full settling in ≤2486 μs with FIR1111 filter enabled.

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-200-RE | Same DMP-4 package and BCC-200 mode, but adds EEPROM-based user-programmable ID and extended diagnostic logging | Required where traceability or field-upgradable calibration is mandated (e.g., Tier-1 OEM production lines) | Select MLX90372GVS-BCC-200-RE only if 48-bit ID persistence across power cycles and enhanced diagnostic data retention are needed |
| TLV493DW2B6HTSA1 | 3-axis Hall sensor with I²C interface; 12-bit resolution but no on-chip DSP, PWM, or ASIL-B certification | Suitable for non-safety-critical consumer or industrial linear sensing where host MCU handles signal processing | Choose TLV493DW2B6HTSA1 only for cost-sensitive designs without functional safety requirements and with available MCU resources for interpolation and filtering |
Compared with MLX90371GVS-BCC-200-RE, the MLX90372 variant adds persistent programmability for production traceability, while the TLV493D requires external processing and lacks automotive safety qualification-making MLX90371GVS-BCC-200-RE the optimal choice for ASIL-B-compliant linear position sensing with integrated output and minimal BOM count.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-200-RE?
The MLX90371GVS-BCC-200-RE operates from −40°C to +160°C, validated per AEC-Q100 Grade 0 qualification. This range covers under-hood automotive environments including engine compartments and brake modules. The device maintains ±10° thermal accuracy across this span, and its DMP-4 package eliminates PCB-related thermal stress limitations found in SOIC-8 variants.
Does the MLX90371GVS-BCC-200-RE require external capacitors?
No, the MLX90371GVS-BCC-200-RE does not require external decoupling capacitors. Its DMP-4 package integrates internal capacitance for the on-chip regulator, as confirmed in section 15.3 of the datasheet. This eliminates layout area and reduces bill-of-materials cost compared to SOIC-8 or TSSOP-16 versions that require external VDEC capacitors.
How is stray-field immunity implemented in the MLX90371GVS-BCC-200-RE?
The MLX90371GVS-BCC-200-RE achieves stray-field immunity through its Linear Stray-Field Immune Mode (BCC-200), which uses differential Triaxis® sensing and proprietary on-chip algorithms to reject in-plane magnetic interference up to ±25 mT while preserving sensitivity to the Z-axis field ≥100 mT. This is distinct from standard mode and requires correct magnet orientation per section 8.3 of the datasheet.
Can the MLX90371GVS-BCC-200-RE output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-200-RE supports either ratiometric analog or PWM output-not both simultaneously. The output mode is selected during programming via the USEROPTION_OUTMODE parameter. Analog mode offers 12-bit resolution with 200 V/ms slew rate; PWM mode provides 12-bit resolution at 150–2000 Hz with programmable duty cycle and built-in diagnostics.
Is the MLX90371GVS-BCC-200-RE certified to ISO26262 ASIL-B?
Yes, the MLX90371GVS-BCC-200-RE is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC). This means it provides documented safety mechanisms-including watchdog timers, memory ECC, and diagnostic coverage-for integration into ASIL-B systems without requiring additional hardware redundancy. Full safety manual documentation is provided by Melexis.
