Product details
Overview
MLX90371GVS-BCC-253-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 programmable stray-field immune operation in Linear Stray-Field Immune Mode. It operates from -40°C to +160°C, supports ratiometric analog or PWM output, and integrates on-chip DSP, NVRAM, and diagnostics for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-253-SP datasheet, pinout, applications, or equivalent options, this device offers verified ISO26262 ASIL-B safety element out-of-context compliance, DMP-4 package compatibility, and end-user programmable transfer characteristics for linear displacement measurement under high EMC stress.
Technical Context
The MLX90371GVS-BCC-253-SP implements Triaxis® Hall sensing with integrated IMC to resolve all three orthogonal magnetic flux components (BX, BY, BZ), enabling robust absolute position decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning, FIR filtering (configurable filter depth), and programmable piecewise-linear interpolation (up to 32 segments) for linear output mapping.
This variant uses Linear Stray-Field Immune Mode (BCC-2xx option code), features dual-mold DMP-4 packaging with straight leads (STD2 2.54 mm pitch), and delivers 440–462 µs latency with ≤2.486 ms step response under worst-case FIR1111 + HYST=1/4 configuration - optimized for fast-response automotive linear sensors requiring immunity to external magnetic interference.

IC Role / Device Role / Timing Role: Contactless linear position detector replacing potentiometers in harsh, sealed environments. Use Value: No moving contacts or wipers - eliminates wear-out failure mode; stray-field immunity prevents false readings from adjacent wiring harnesses. |
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-250-SP | DMP-4 package, Linear Stray-Field Immune Mode, 100 nF integrated VDEC capacitor (BCC-250 vs. BCC-253's 10 nF). | Higher output capacitance increases settling time; less suitable for fast-response systems requiring <500 µs latency. | Select BCC-250 only if system-level EMC testing confirms lower bandwidth acceptable and board layout lacks space for external decoupling. |
| MLX90372GVS-BCC-253-SP | Successor generation with enhanced ASIL-B diagnostic coverage, extended 16-bit resolution, and improved thermal drift (±8-bit vs. ±10-bit). | Requires updated programming toolchain and firmware; not drop-in compatible due to NVRAM structure changes. | Choose MLX90372GVS-BCC-253-SP for new designs targeting higher functional safety integrity or tighter linearity specs. |
Compared with MLX90371GVS-BCC-253-SP, the BCC-250 variant trades speed for EMC margin via larger on-die capacitor, while the MLX90372 offers higher resolution and stronger diagnostics at the cost of firmware migration effort - making the BCC-253 optimal for cost-sensitive, latency-critical linear sensing where legacy toolchain reuse is required.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-253-SP?
The MLX90371GVS-BCC-253-SP is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports placement in high-temperature zones such as engine compartments, transmission housings, and brake modules. The device maintains specified accuracy and latency performance across this full range, with thermal compensation applied in firmware to sustain ±10-bit accuracy.
Does the MLX90371GVS-BCC-253-SP require external decoupling capacitors?
No, the MLX90371GVS-BCC-253-SP does not require external decoupling capacitors. Its DMP-4 package integrates a 10 nF capacitor on-die at the VDEC node (confirmed by BCC-253 option code), eliminating the need for discrete components and reducing PCB area. This integration is validated for stable operation under automotive load dump and ripple conditions per ISO 7637-2.
How is stray-field immunity implemented in the MLX90371GVS-BCC-253-SP?
The MLX90371GVS-BCC-253-SP achieves stray-field immunity through its Linear Stray-Field Immune Mode (BCC-2xx), which uses differential Triaxis® sensing and proprietary on-chip signal processing to reject common-mode magnetic interference up to ±1 T. This mode is factory-configured and verified per IEC 61000-4-8 test protocols, ensuring reliable linear position output even when mounted near high-current actuators or motors.
Can the MLX90371GVS-BCC-253-SP output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-253-SP supports either ratiometric analog or PWM output - not both simultaneously. Output mode is selected during end-user programming via the NVRAM configuration interface. The analog output provides 0–100% VDD scaling with 12-bit resolution, while PWM offers 150–2000 Hz frequency and 0–100% duty cycle, each optimized for different ECU input architectures.
What safety certification does the MLX90371GVS-BCC-253-SP hold?
The MLX90371GVS-BCC-253-SP is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC). This includes documented fault detection mechanisms (ECC-protected NVRAM, watchdog timers, broken-wire diagnostics), diagnostic coverage metrics, and safety manual support - enabling direct integration into ASIL-B automotive systems without additional hardware redundancy.
