Product details
Overview
MLX90371GVS-BCC-201-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° thermal accuracy over -40°C to +160°C, and stray-field immunity in Linear Stray-Field Immune 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-201-RX datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed pin functions (VDD/VSS/OUT), real-world timing specs (440–462 µs latency), functional safety compliance (ISO 26262 ASIL-B SEooC), and validated alternatives for linear position sensing in harsh environments.
Technical Context
The MLX90371GVS-BCC-201-RX implements Triaxis® Hall sensing with on-chip DSP, ADC, and NVRAM to decode absolute linear displacement from magnet motion using calibrated X/Y/Z field vector processing. Its architecture includes FIR filtering (configurable 1/11/1111 taps), exponential moving average, and programmable clamping for robust signal conditioning.
This variant is factory-configured for Linear Stray-Field Immune Mode (BCC-2xx), enabling accurate position measurement under external magnetic interference up to ±1 T. It supports user-programmable transfer characteristics-4/8-point LNR or 16/32-segment PWL-and dual-output modes: ratiometric analog (0–100% VDD) or PWM (150–2000 Hz).

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-201-RX | Same DMP-4 package and Linear Stray-Field Immune Mode, but adds 48-bit unique ID and enhanced diagnostic coverage per ISO 26262 ASIL-B. | Required where traceability (e.g., VIN-linked calibration) or higher diagnostic fault coverage is mandated. | Select MLX90372GVS-BCC-201-RX if 48-bit ID or extended diagnostic logging is needed; otherwise MLX90371GVS-BCC-201-RX suffices for standard ASIL-B compliance. |
| AMS AS5600-WSCT | 12-bit contactless rotary encoder with I²C interface; no stray-field immunity; max operating temp +85°C; requires external magnet and PCB layout. | Limited to benign environments (e.g., infotainment knobs); unsuitable for under-hood linear position sensing. | Only consider AMS AS5600-WSCT for cost-sensitive, non-automotive rotary applications; not a functional replacement for MLX90371GVS-BCC-201-RX in automotive linear sensing. |
Compared with MLX90372GVS-BCC-201-RX, the MLX90371GVS-BCC-201-RX offers identical core sensing performance and packaging but omits 48-bit ID and advanced diagnostics - making it optimal for volume automotive applications where those features are unnecessary. Against AMS AS5600-WSCT, MLX90371GVS-BCC-201-RX provides superior thermal range, stray-field resilience, and integrated output drivers - essential for functional safety-critical linear position tasks.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-201-RX?
The MLX90371GVS-BCC-201-RX is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports placement in demanding under-hood locations such as near transmissions, exhaust manifolds, or brake modules where ambient heat and thermal cycling are extreme. The device maintains specified accuracy and latency performance across this full range without derating.
Does the MLX90371GVS-BCC-201-RX require external decoupling capacitors?
No, the MLX90371GVS-BCC-201-RX does not require external decoupling capacitors. Its DMP-4 package integrates a 100 nF ceramic capacitor internally between VDD and VSS, eliminating the need for board-level bypass components. This reduces PCB area, simplifies layout, and improves reliability by removing solder joint failure points - a key advantage for high-vibration automotive deployments.
How is stray-field immunity implemented in the MLX90371GVS-BCC-201-RX?
The MLX90371GVS-BCC-201-RX achieves stray-field immunity through its Linear Stray-Field Immune Mode (BCC-201 configuration), which uses differential Triaxis® sensing and proprietary on-chip signal processing to reject orthogonal magnetic interference up to ±1 T. This mode is factory-programmed and does not require user calibration - ensuring consistent rejection of fields from nearby motors, solenoids, or current-carrying traces without sacrificing position accuracy.
Can the MLX90371GVS-BCC-201-RX output both analog and PWM simultaneously?
No, the MLX90371GVS-BCC-201-RX supports only one active output mode at a time: either ratiometric analog voltage (0–100% VDD) or PWM (150–2000 Hz). The output type is selected during programming via the NVRAM configuration and cannot be dynamically switched in runtime. This single-mode design ensures deterministic timing, minimized EMI, and simplified ECU interface design for safety-critical applications.
What safety certification does the MLX90371GVS-BCC-201-RX hold?
The MLX90371GVS-BCC-201-RX is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC). This means it has been developed according to ASIL-B requirements - including systematic fault tolerance, diagnostic coverage, and verification - and can be integrated into ASIL-B or lower automotive safety architectures without requiring additional safety mechanisms at the IC level.
