Product details
Overview
MLX90371GVS-BCC-200-SP 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 operates from -40°C to +160°C, supports programmable ratiometric analog or PWM output, and is qualified per ISO 26262 ASIL-B as a Safety Element out of Context.
For engineers reviewing the MLX90371GVS-BCC-200-SP datasheet, pinout, applications, or equivalent options, this device serves as a robust, programmable, non-contacting replacement for potentiometers in automotive throttle, pedal, and ride height sensing where magnetic stray-field rejection and functional safety compliance are critical.
Technical Context
The MLX90371GVS-BCC-200-SP implements on-chip DSP-based signal processing to decode absolute linear displacement from triaxial Hall measurements, using finite impulse response (FIR) filtering with selectable tap configurations (FIR1/FIR11/FIR1111) and exponential moving average filtering. Its architecture includes integrated voltage regulation, reverse-polarity and overvoltage protection, and dual-stage diagnostics including active and passive broken-wire detection.
This variant is factory-configured for Linear Stray-Field Immune Mode (BCC-200), enabling accurate position measurement under external magnetic interference up to ±1 T, with programmable transfer characteristics (4/8-point LNR or 16/32-segment PWL), 48-bit unique ID, and configurable output latency (440–462 µs typical).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit digital resolution with 10-bit thermal accuracy ensures stable linear position reporting across full temperature range (-40°C to +160°C). |
| Operating Voltage | 4.5 V to 5.5 V supply enables direct integration into 5 V automotive domains without external regulation. |
| Supply Current | 6–10 mA typical in Linear Stray-Field Immune Mode reduces thermal load and simplifies power budgeting in space-constrained modules. |
| Latency Time | 440–462 µs ensures fast closed-loop control response for real-time applications like electronic throttle control. |
| PWM Frequency Range | 150 Hz to 2 kHz allows flexible ECU synchronization and noise immunity tuning in electrically noisy vehicle environments. |
| Magnetic Immunity | Stray-field immune operation up to ±1 T enables reliable function near motors, solenoids, or high-current cables without shielding. |
| Safety Certification | ISO 26262 ASIL-B Safety Element out of Context (SEooC) provides pre-validated safety evidence for automotive system integration. |
Pinout & Package
DMP-4 (Dual Mold Package) - compact, PCB-less surface-mount package with 4 terminals, optimized for direct soldering onto flex or rigid boards in space-constrained automotive sensors.
| Pin/Terminal | Circuit Role | Design Meaning |

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-100-SP | Configured for Rotary Stray-Field Immune Mode; optimized for 0–360° angular measurement with different magnetic circuit requirements. | Requires rotary magnet assembly and angular calibration; not suitable for linear stroke without mechanical conversion. | Select only when measuring rotational position with stray-field immunity; incompatible pin-level programming for linear transfer functions. |
| MLX90372GVS-BCC-200-SP | Successor IC with enhanced 14-bit resolution, lower latency (380 µs), and extended magnetic range (±1.5 T); shares same DMP-4 package and pinout. | Provides higher precision and faster response but requires updated programming tools and firmware support for new memory map. | Preferred for new designs demanding improved accuracy or tighter control loops; backward-compatible mechanically but not electrically identical. |
Compared with MLX90371GVS-BCC-200-SP, the BCC-100 variant delivers rotary position with identical safety and package benefits but mismatched transfer function targeting, while the MLX90372 offers measurable latency and resolution gains at the cost of toolchain updates-making the original optimal for cost-sensitive, volume-qualified linear sensing programs.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-200-SP?
The MLX90371GVS-BCC-200-SP is specified for continuous operation from -40°C to +160°C, validated per automotive qualification standards. This range covers under-hood and chassis-mounted locations including throttle bodies, suspension modules, and brake actuators. The device maintains 12-bit resolution and thermal accuracy within this envelope, with junction temperature limited to +175°C. All electrical and magnetic specifications in the datasheet apply across this full range unless otherwise noted.
Does the MLX90371GVS-BCC-200-SP require external programming hardware?
Yes, the MLX90371GVS-BCC-200-SP requires Melexis' official programming tools-including the EVB90371 evaluation board and MLX IDE software-to configure its transfer characteristic, output mode (analog/PWM), diagnostics, and clamping levels. Factory-default settings enable immediate use in Linear Stray-Field Immune Mode, but full calibration and application-specific tuning must be performed post-soldering using the I²C-compatible TEST pin interface. No external EEPROM or MCU is needed for runtime operation once programmed.
What package type does the MLX90371GVS-BCC-200-SP use, and what are its mounting requirements?
The MLX90371GVS-BCC-200-SP uses the DMP-4 (Dual Mold Package), a PCB-less surface-mount package with four solderable terminals. It is designed for direct attachment to flex circuits or rigid PCBs using standard reflow profiles. The package has no internal substrate-electrical connections are made solely through its molded leads-and requires no underfill. Mounting orientation must align the sensitive spot (center of die) with the target magnet's linear travel axis, per Melexis' DMP-4 positioning guidelines in section 18.3.6 of the datasheet.
How does the Linear Stray-Field Immune Mode (BCC-200) differ from Standard Mode?
The Linear Stray-Field Immune Mode (BCC-200) configures the MLX90371GVS-BCC-200-SP's internal signal processing to reject magnetic interference orthogonal to the intended linear measurement axis, allowing operation in fields up to ±1 T without shielding. Standard Mode (BCC-300) uses legacy algorithms optimized for sensitivity over immunity and lacks this rejection capability. BCC-200 also sets default filter and latency parameters suited for linear stroke applications, whereas Standard Mode targets backward compatibility with earlier MLX90363 designs.
Can the MLX90371GVS-BCC-200-SP output both analog and PWM simultaneously?
No, the MLX90371GVS-BCC-200-SP supports only one active output mode at a time-either ratiometric analog (0–100% VDD) or PWM (150–2000 Hz)-selected during programming. The output stage is single-ended and shared across both modes; simultaneous dual-output is not implemented. Switching between modes requires reprogramming via the TEST pin interface and a power cycle. Output selection is stored in NVRAM and persists across power cycles.
