Product details
Overview
MLX90371GGO-BCC-200-RE from Melexis is a Triaxis® monolithic position processor IC that measures all three orthogonal magnetic field components (BX, BY, BZ) to deliver absolute linear position output with 12-bit resolution and ±10-bit thermal accuracy. It operates from -40°C to +160°C, supports programmable PWM or ratiometric analog output, and implements Linear Stray-Field Immune Mode for robust operation in electrically noisy automotive environments such as throttle and pedal position sensing.
For engineers reviewing the MLX90371GGO-BCC-200-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, package-specific terminal mapping, real-world use cases, and validated alternative options for automotive-grade absolute position sensing designs requiring ASIL-B compliance and stray-field immunity.
Technical Context
The MLX90371GGO-BCC-200-RE integrates on-chip DSP, ADC, and NVRAM to perform real-time 3D magnetic field vector processing and generate calibrated position data. Its Linear Stray-Field Immune Mode (BCC-200) uses proprietary signal conditioning to reject interfering in-plane fields while preserving sensitivity to axial (Z-axis) field gradients required for linear displacement measurement.
This variant employs a TSSOP-16 dual-die package with isolated internal domains, enabling independent power/ground paths for analog and digital sections. It supports user-programmable transfer characteristics via 4-, 8-, or 32-segment piecewise-linear interpolation and includes integrated reverse-polarity and overvoltage protection on VDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive placement without external thermal derating |
| Output Resolution | 12-bit - delivers 4096 discrete position steps across full range for high-precision feedback control |
| Thermal Accuracy | ±10-bit - maintains ≤0.1% full-scale error drift over full temperature range without external calibration |
| Supply Current | 6–10 mA - low quiescent draw enables use in always-on vehicle subsystems with strict power budgets |
| Latency Time | 440–462 μs - deterministic response time suitable for closed-loop engine and transmission control loops |
| PWM Frequency | 150–2000 Hz - configurable output rate compatible with standard ECU input capture peripherals |
| Magnetic Immunity | Linear Stray-Field Immune Mode - rejects interference from adjacent motors, solenoids, or wiring harnesses during linear position tracking |
Pinout & Package
TSSOP-16 package with dual-die isolation architecture; requires separate VDD1/VDD2, VSSA1/VSSA2, VSSD1/VSSD2, and VDEC1/VDEC2 connections to maintain signal integrity and EMC robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | On-chip regulator decoupling pins - must be connected to local 100nF ceramic capacitors for stable internal voltage generation |
| 2, 10 | VSSA1 / VSSA2 | Analog ground reference - dedicated low-noise return path for sensor front-end and ADC |
| 3, 11 | VDD1 / VDD2 | Primary supply inputs - support 4.5–5.5 V operation; dual inputs enable redundancy or split-domain biasing |
| 4, 12 | Test Input1 / Test Input2 | Factory test access points - not intended for end-user connection; recommended to tie to ground for EMC |
| 5, 13 | Test2 / Test1 | Factory test access points - unused in application; grounding improves radiated emissions performance |
| 6, 15 | OUT2 / OUT1 | Dual independent outputs - support redundant or differential signaling; each configurable as analog or PWM |
| 7, 14 | Not Used2 / Not Used1 | No internal connection - must be grounded per Melexis EMC guidelines to prevent parasitic coupling |
| 8, 16 | VSSD2 / VSSD1 | Digital ground reference - isolated return path for DSP, memory, and output stage logic |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Sensing | Simultaneous BX/BY/BZ measurement enables true absolute position decoding without mechanical cam or gear constraints |

| Stray-Field Immunity | Linear Stray-Field Immune Mode (BCC-200) suppresses >95% of in-plane interference while preserving Z-axis gradient sensitivity for linear motion |
| Integrated Protection | Built-in reverse-polarity (-14 V), overvoltage (45 V), and short-circuit (-30/+30 mA) protection eliminate need for external protection circuitry |

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 |
|---|---|---|---|
| MLX90371GDC-BCC-200-RE | SOIC-8 single-die package; lower pin count, no dual-domain isolation; 3000 pcs/reel packaging | Lacks TSSOP-16's dual-die isolation and EMC headroom; suitable for cost-sensitive non-safety-critical linear sensors | Select when board space is constrained and ASIL-B decomposition is handled externally; verify layout-level noise immunity. |
| MLX90371GVS-BCC-200-RE/RX | DMP-4 PCB-less package with straight leads; 2500 pcs/reel; integrated 100nF decoupling capacitors | Eliminates external capacitor footprint but reduces thermal mass and repairability; optimized for ultra-compact modules | Choose for embedded actuator modules where size and assembly simplicity outweigh serviceability requirements. |
Compared with MLX90371GGO-BCC-200-RE, the SOIC-8 variant trades dual-die isolation and higher packing density for lower cost and smaller footprint, while the DMP-4 version sacrifices testability and thermal dissipation for minimal form factor and built-in decoupling-making the TSSOP-16 the optimal choice for ASIL-B automotive subsystems demanding highest EMC resilience and functional safety headroom.

FAQ
What is the operating temperature range of the MLX90371GGO-BCC-200-RE?
The MLX90371GGO-BCC-200-RE is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements for under-hood automotive placement. This range is validated across all electrical parameters including supply current, output accuracy, and latency, eliminating need for external thermal compensation in engine control or transmission modules where the MLX90371GGO-BCC-200-RE is deployed.
How does the Linear Stray-Field Immune Mode (BCC-200) function in the MLX90371GGO-BCC-200-RE?
The Linear Stray-Field Immune Mode in the MLX90371GGO-BCC-200-RE actively suppresses interfering in-plane magnetic fields (BX/BY) while preserving sensitivity to axial (BZ) gradients required for linear displacement measurement. This is achieved through on-chip DSP algorithms and differential front-end topology, enabling accurate position reporting even when mounted near high-current actuators-verified in MLX90371GGO-BCC-200-RE application testing per ISO 11452-8.
Can the MLX90371GGO-BCC-200-RE output both analog and PWM signals simultaneously?
No, the MLX90371GGO-BCC-200-RE supports either ratiometric analog or PWM output per channel, but not both simultaneously on the same pin. Its dual-output TSSOP-16 configuration allows independent programming of OUT1 and OUT2-e.g., one as analog for primary feedback and the other as PWM for redundancy-providing flexibility without requiring external signal conversion hardware in the MLX90371GGO-BCC-200-RE implementation.
What safety certifications apply to the MLX90371GGO-BCC-200-RE?
The MLX90371GGO-BCC-200-RE is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC), with documented safety mechanisms including memory ECC, watchdog timers, and diagnostic coverage for internal faults. This certification applies specifically to the MLX90371GGO-BCC-200-RE variant and permits its integration into ASIL-B automotive systems without requiring additional hardware-level fault containment, per Melexis Safety Manual Rev. 004.
What package type and pin count does the MLX90371GGO-BCC-200-RE use?
The MLX90371GGO-BCC-200-RE uses a TSSOP-16 surface-mount package with dual-die construction, featuring 16 terminals including two independent outputs (OUT1/OUT2), dual supply/ground pairs (VDD1/VDD2, VSSA1/VSSA2, VSSD1/VSSD2), and two decoupling pins (VDEC1/VDEC2). This configuration is explicitly defined in the MLX90371GGO-BCC-200-RE ordering information and pin definition tables of the official datasheet.
