Product details
Overview
MLX90371GVS-BCC-208-RX 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-bit thermal accuracy, and stray-field immunity in Linear Stray-Field Immune Mode. It supports programmable ratiometric analog or PWM output and operates from -40°C to +160°C in automotive-grade DMP-4 packaging.
For engineers reviewing the MLX90371GVS-BCC-208-RX datasheet, pinout, applications, or equivalent options, this part delivers certified ASIL-B functional safety compliance, configurable piecewise-linear transfer characteristics (up to 32 segments), and robust EMC performance in compact PCB-less DMP-4 form factor for space-constrained automotive sensing.
Technical Context
The MLX90371GVS-BCC-208-RX implements on-chip DSP-based signal processing of triaxial Hall sensor data to decode absolute linear displacement without mechanical contact. Its architecture includes integrated ADC, temperature compensation, FIR filtering (configurable up to 4-stage), and programmable diagnostic logic including broken-wire detection.
This variant operates exclusively in Linear Stray-Field Immune Mode (BCC-2xx option code), enabling accurate position measurement under external magnetic interference up to ±1 mT. It uses a dedicated DMP-4 package with internal decoupling and dual ground pins optimized for high-vibration environments.

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 |
|---|---|---|---|
| MLX90371GVS-BCC-200-RE | Same DMP-4 package and Linear Stray-Field Immune Mode, but delivered in standard tape-and-reel (RE) orientation instead of face-down RX format. | Identical functional performance; differs only in packaging orientation for pick-and-place compatibility. | Select BCC-200-RE when standard top-side-up placement is required; BCC-208-RX is preferred for automated assembly with vision-guided feeders requiring bottom-side fiducials. |
| MLX90372GVS-BCC-208-RX | Successor device with enhanced 14-bit resolution, extended 200°C junction rating, and updated ASIL-B safety manual revision. | Supports higher-temperature zones (e.g., near turbochargers); requires firmware update for diagnostic register mapping. | Choose MLX90372GVS-BCC-208-RX for new designs targeting extended thermal margin or future-proofing; MLX90371GVS-BCC-208-RX remains optimal for cost-sensitive volume programs with validated qualification. |
Compared with MLX90371GVS-BCC-208-RX, the BCC-200-RE offers identical electrical and magnetic performance with standard tape orientation, while the MLX90372GVS-BCC-208-RX adds resolution and thermal headroom at higher BOM cost and minor software integration effort.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-208-RX?
The MLX90371GVS-BCC-208-RX is rated for continuous operation from -40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. This range is validated across all electrical parameters including supply current, output accuracy, and latency time, making it suitable for under-hood and transmission-mounted automotive applications where thermal stability is critical. The device incorporates on-die temperature compensation to maintain 12-bit linearity across the full range.
Does the MLX90371GVS-BCC-208-RX require external decoupling capacitors?
No, the MLX90371GVS-BCC-208-RX does not require external decoupling capacitors. Its DMP-4 package integrates internal decoupling functionality via the VDEC structure, and the datasheet explicitly states "built-in capacitors" for DMP-4 variants. The pinout omits a dedicated VDEC pin because regulation and filtering are handled internally - confirmed in Section 15.3 of the datasheet and Table 5 pin definitions.
How is stray-field immunity implemented in the MLX90371GVS-BCC-208-RX?
The MLX90371GVS-BCC-208-RX achieves stray-field immunity through hardware-level differential sensing of BX/BY/BZ components combined with proprietary on-chip DSP algorithms specific to Linear Stray-Field Immune Mode (BCC-208). This mode rejects uniform external fields up to ±1 T while preserving sensitivity to the target magnet's spatial gradient, as verified in Section 8.3 of the datasheet. No external shielding or calibration is needed.
Can the MLX90371GVS-BCC-208-RX output both analog and PWM simultaneously?
No, the MLX90371GVS-BCC-208-RX supports only one output mode at a time: either ratiometric analog voltage or PWM signal. The output type is selected during end-user programming via the USEROPTION_OUTMODE parameter (Section 13.1.1), and the hardware output stage is configured accordingly. Simultaneous dual-output operation is not supported in any MLX90371 variant, including BCC-208-RX.
What safety documentation is provided for the MLX90371GVS-BCC-208-RX?
The MLX90371GVS-BCC-208-RX is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC), with a complete safety manual (Revision 004, March 2019) covering diagnostic coverage, FMEDA data, safety mechanisms (e.g., memory ECC, watchdog timers, broken-wire detection), and integration guidelines. All safety-relevant parameters - including diagnostic cycle time, fault reaction time, and safe failure fraction - are specified in Sections 14.1 and 14.2 of the official datasheet.
