Product details

Overview

MLX90371GGO-BCC-200-SP 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 ±10-bit thermal accuracy. It operates from -40°C to +160°C, supports programmable PWM or ratiometric analog output, and implements stray-field immune linear mode per BCC-200 configuration for automotive pedal and throttle sensing.

For engineers reviewing the MLX90371GGO-BCC-200-SP datasheet, pinout, applications, or equivalent options, this device delivers ISO26262 ASIL-B safety element out-of-context compliance, programmable piecewise-linear transfer characteristics (up to 32 segments), and robust operation in high-EMI environments typical of powertrain and chassis control systems.

Technical Context

The MLX90371GGO-BCC-200-SP uses integrated magnetic concentrators and on-chip DSP to decode absolute linear displacement from magnet motion, with dedicated firmware for Linear Stray-Field Immune Mode. Its architecture includes dual ADCs for VX/VY/VZ acquisition, FIR filtering (configurable up to 4-stage), and real-time temperature compensation applied to both magnetic and output stages.

This variant features fixed 12-bit PWM output with 150–2000 Hz frequency range, 440–462 µs latency, and 968–5099 µs step response depending on filter selection. The DMP-4 package enables direct PCB-less mounting with internal decoupling, and its dual-ground pin layout minimizes ground bounce in noisy automotive environments.

Key Features

Feature	Design Value
Triaxis® Sensing	Simultaneous BX/BY/BZ measurement enables absolute linear position decoding without mechanical wipers or potentiometers.
Stray-Field Immunity	BCC-200 mode rejects interfering fields orthogonal to the target magnet's linear motion axis-critical for under-hood placement near motors or solenoids.
Programmable Transfer Curve	Up to 32-segment piecewise-linear calibration allows precise matching to non-uniform mechanical travel profiles (e.g., accelerator pedal).
On-Chip Diagnostics	Active diagnostics (open/short detection) and passive broken-wire monitoring (VDD/VSS loss) support functional safety requirements without external circuitry.
Integrated Decoupling	DMP-4 package embeds internal capacitors, eliminating need for external VDEC components and reducing board area by >30% vs SOIC-8 designs.

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
MLX90371GGO-BCC-100-SP	Rotary Stray-Field Immune Mode; optimized for 0–360° angular measurement with different magnetic field sensitivity thresholds.	Designed for rotary applications (steering angle, camshaft position); not validated for linear stroke accuracy or BCC-200 transfer function.	Select only when angular position-not linear displacement-is required; requires reprogramming and magnetic circuit redesign.
MLX90371GVS-BCC-200-SP	Same BCC-200 linear mode but in SOIC-8 package; lacks integrated decoupling capacitors and DMP-4 mechanical ruggedness.	Suitable for prototyping or legacy PCBs; requires external 100 nF VDEC capacitor and exhibits higher susceptibility to board-level vibration.	Choose for cost-sensitive non-automotive applications where PCB space and mechanical stress are not constraints.

Compared with MLX90371GGO-BCC-200-SP, the BCC-100 variant provides rotary-specific field immunity and angular calibration, while the SOIC-8 version trades DMP-4's embedded decoupling and mechanical resilience for lower assembly cost and broader footprint compatibility.

FAQ

What is the operating temperature range of the MLX90371GGO-BCC-200-SP?

The MLX90371GGO-BCC-200-SP is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports under-hood automotive placements such as throttle bodies and brake boosters where ambient heat and thermal cycling are extreme. The device maintains specified accuracy and latency performance across this full range due to on-chip temperature compensation applied to both magnetic front-end and output stages.

How does the BCC-200 option affect the MLX90371GGO-BCC-200-SP's magnetic performance?

The BCC-200 option configures the MLX90371GGO-BCC-200-SP for Linear Stray-Field Immune Mode, optimizing its internal gain and filtering for linear magnet motion along one axis while rejecting interference from orthogonal magnetic fields. This mode specifies distinct magnetic flux density thresholds (e.g., BZ ≥ 100 mT) and gradient limits defined in Section 8.3 of the datasheet, ensuring reliable operation near motors or solenoids where stray fields exceed 25 mT.

Can the MLX90371GGO-BCC-200-SP output both analog and PWM simultaneously?

No, the MLX90371GGO-BCC-200-SP supports either ratiometric analog or PWM output-not both concurrently. Output mode is selected during programming via the USEROPTION_OUTMODE parameter. In analog mode, OUT delivers a voltage proportional to VDD (0–100%); in PWM mode, it outputs a duty-cycle-modulated signal (150–2000 Hz). Switching modes requires reprogramming and power cycle; no runtime reconfiguration is supported.

What package type does the MLX90371GGO-BCC-200-SP use, and why is it significant?

The MLX90371GGO-BCC-200-SP uses the DMP-4 (Dual Mold Package), a 4-pin, PCB-less surface-mount module with integrated decoupling capacitors. This eliminates external VDEC components, reduces board area by >30%, and enhances mechanical robustness against vibration and thermal stress-key for automotive suspension and powertrain sensors where reliability under shock and thermal cycling is critical.

Does the MLX90371GGO-BCC-200-SP require external programming hardware?

Yes, the MLX90371GGO-BCC-200-SP requires Melexis' official programming tools (e.g., EVB90371 evaluation board with PTC-04 programmer) to configure parameters such as output mode, transfer characteristic (4/8/16/32-point), diagnostic settings, and clamping levels. Factory-programmed units ship with default settings, but application-specific calibration-including BCC-200 linear mode parameters-must be performed before deployment.
