Product details
Overview
MLX90371GVS-BCC-200-RX from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute linear position output with 12-bit resolution and ±1.5° thermal accuracy over –40°C to +160°C. It operates from 4.5–5.5 V, draws 6–10 mA, and supports programmable PWM or ratiometric analog output in Linear Stray-Field Immune Mode for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-200-RX datasheet, pinout, applications, or equivalent options, this page provides verified functional context, DMP-4 package terminal mapping, real-world use cases in ride height and float-level systems, and validated alternative options for ASIL-B-compliant position sensing designs.
Technical Context
The MLX90371GVS-BCC-200-RX implements Triaxis® Hall sensing with on-chip DSP, ADC, and NVRAM to decode absolute linear displacement from magnet motion using piecewise-linear (16- or 32-segment) transfer functions. Its architecture includes integrated reverse-polarity and overvoltage protection, programmable diagnostic modes (broken-wire detection), and configurable FIR filtering for latency control.
This variant is factory-configured for Linear Stray-Field Immune Mode (BCC-200), enabling robust operation under external magnetic interference up to ±1 T while maintaining <±0.5% INL across its calibrated range. It uses a dual-mold DMP-4 package with two ground pins, one supply, and one output-optimized for PCB-less mounting in space-constrained automotive actuators.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-200-RX?
The MLX90371GVS-BCC-200-RX is qualified for continuous operation from –40°C to +160°C ambient temperature, with junction temperature up to +175°C. This rating is validated per AEC-Q100 Grade 0 and supports placement in engine compartments, transmission housings, and brake modules where thermal stress is severe. The MLX90371GVS-BCC-200-RX maintains specified accuracy and latency performance across this full range without derating.
Does the MLX90371GVS-BCC-200-RX support both analog and PWM outputs simultaneously?
No-the MLX90371GVS-BCC-200-RX supports either ratiometric analog output or PWM output, selected at programming time via NVRAM configuration. The output mode is fixed after final calibration and cannot be dynamically switched in-circuit. The MLX90371GVS-BCC-200-RX does not provide dual-output capability; users must choose the interface type matching their ECU's input requirements during design-in.
How is stray-field immunity implemented in the MLX90371GVS-BCC-200-RX?
The MLX90371GVS-BCC-200-RX achieves stray-field immunity through differential Triaxis® sensing combined with proprietary on-chip signal processing that rejects orthogonal magnetic interference up to ±1 T. In Linear Stray-Field Immune Mode (BCC-200), it uses dedicated compensation algorithms and internal IMC structures to isolate the useful Z-axis field component from interfering X/Y fields. This is verified per ISO 11452-8 test standards and documented in Section 8.3 of the MLX90371GVS-BCC-200-RX datasheet.
What package type does the MLX90371GVS-BCC-200-RX use, and what are its mounting requirements?
The MLX90371GVS-BCC-200-RX uses the DMP-4 (Dual Mold Package) - a 4-pin, PCB-less surface-mount device with straight leads (STD4 2.54 mm pitch). It is designed for direct soldering onto flex circuits, metal substrates, or custom carriers. No PCB footprint is required; thermal and mechanical anchoring rely on solder joint integrity and optional adhesive backing. Mounting must follow Melexis' DMP-4 guidelines in Section 18.3.4 of the MLX90371GVS-BCC-200-RX datasheet.
Is the MLX90371GVS-BCC-200-RX certified for functional safety applications?
Yes-the MLX90371GVS-BCC-200-RX is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC), with full safety manual (document MLX90371-SM-001) and diagnostic coverage analysis provided by Melexis. It includes built-in diagnostics such as memory ECC, watchdog timers, and supply monitoring. The MLX90371GVS-BCC-200-RX enables integration into ASIL-B systems without requiring redundant sensors or external safety monitors.
