Product details
Overview
MLX90371GVS-BCC-201-SP from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute rotary or linear position output with 12-bit resolution and ±10-bit thermal accuracy. It operates from -40°C to +160°C, supports programmable analog ratiometric or PWM output, and implements ISO26262 ASIL-B safety element out-of-context for automotive pedal, throttle, and ride height sensing.
For engineers reviewing the MLX90371GVS-BCC-201-SP datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DMP-4), confirmed stray-field immune linear mode operation, real-world timing specs (462 μs latency), and validated alternatives for functional replacement in high-reliability automotive sensor designs.
Technical Context
The MLX90371GVS-BCC-201-SP implements a dedicated Triaxis® Hall front-end with integrated IMC, on-chip DSP for real-time 3D field vector processing, and configurable FIR/EMA filtering. Its architecture enables robust decoding of magnet position under stray-field interference via differential field rejection in Linear Stray-Field Immune Mode (BCC-2xx).
This variant uses a DMP-4 package with dual ground pins (Pin 1 & Pin 4), single supply (Pin 2), and push-pull output (Pin 3), supporting 150–2000 Hz PWM or ratiometric analog output. Internal diagnostics include broken-wire detection, intelligent watchdog, and programmable clamping-fully compliant with ASIL-B requirements per ISO26262.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments without derating. |
| Supply Voltage | 4.5–5.5 V - stable operation across battery voltage fluctuations in 12 V systems. |
| Output Type | Selectable ratiometric analog or PWM - enables drop-in replacement of potentiometers or integration into digital control loops. |
| Resolution | 12-bit - provides 4096 discrete position steps over full scale for high-precision feedback. |
| Latency Time | 462 μs max - deterministic response critical for closed-loop motor control and active suspension systems. |
| Magnetic Mode | Linear Stray-Field Immune (BCC-201) - rejects orthogonal interference fields up to ±100 mT while maintaining linearity. |
| Safety Certification | ISO26262 ASIL-B SEooC - enables reuse in ASIL-B system architectures without requalification. |
Pinout & Package
DMP-4 package: ultra-compact, PCB-less dual-mold construction with 2.54 mm pitch STD4 trim-and-form leads (BCC-201 suffix), optimized for direct soldering onto flexible substrates or stamped metal carriers in space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (VSS) | Ground | Primary analog/digital return path; must be low-impedance for EMC compliance and diagnostic integrity. |
| Pin 2 (VDD) | Supply Input | 4.5–5.5 V power rail with reverse polarity and overvoltage protection (−14 V / +45 V abs max). |
| Pin 3 (OUT) | Programmable Output | Push-pull stage delivering either ratiometric analog (0–100% VDD) or PWM (150–2000 Hz) signal. |
| Pin 4 (VSS) | Ground | Secondary ground terminal; paralleling with Pin 1 reduces loop inductance and improves noise immunity. |
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 mode (BCC-201) rejects interfering fields orthogonal to the sensing axis-critical near motors, solenoids, or adjacent sensors. |
| Programmable Transfer Curve | Supports 4/8-point LNR or 16/32-segment PWL calibration-eliminates external linearization circuitry and enables custom mechanical-to-electrical mapping. |
| ASIL-B Safety Element | Includes internal diagnostics (broken-wire, watchdog, memory ECC) and safety manual-reduces FMEDA effort in system-level ASIL decomposition. |
| Robust Output Stage | Clampable output with programmable saturation levels (0–100% VDD) prevents false triggering during ESD or load dump events. |
Applications
| Pedal Position Sensing | Throttle Position Sensing |
|---|---|
Use Scenario: Monitoring accelerator or brake pedal angle in electric/hybrid powertrains with high EMC stress and temperature cycling. IC Role / Device Role / Timing Role: Absolute position transducer providing real-time analog/PWM feedback to ECU for torque demand calculation and fail-safe actuation. Use Value: BCC-201's Linear Stray-Field Immune Mode ensures stable output despite proximity to high-current traction inverters and 12 V harness noise. | Use Scenario: Closed-loop control of engine air intake butterfly valve in gasoline direct injection systems. IC Role / Device Role / Timing Role: High-speed position feedback element with ≤462 μs latency enabling precise transient response during tip-in/tip-out events. Use Value: 12-bit resolution and programmable PWL transfer curve match non-linear throttle body geometry without external lookup tables. |
| Ride Height Control | Steering Wheel Angle |
Use Scenario: Active suspension systems adjusting vehicle height based on road profile and load conditions. IC Role / Device Role / Timing Role: Linear displacement sensor mounted on air spring or shock absorber linkage, reporting absolute vertical position. Use Value: DMP-4 package allows direct mounting on moving suspension components; stray-field immunity prevents drift from nearby ABS wheel speed sensors. | Use Scenario: Column-mounted or rack-integrated steering angle measurement for EPS and ADAS lane-keeping functions. IC Role / Device Role / Timing Role: Absolute rotary position encoder delivering 0–360° continuous angle with no homing requirement after power cycle. Use Value: ASIL-B SEooC certification enables direct integration into steering control domain without additional hardware redundancy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-201-SP | Same DMP-4 package and BCC-201 linear mode, but adds EEPROM-based user-programmable ID and extended diagnostic coverage. | Required where traceability, firmware versioning, or enhanced fault logging is mandated by OEM specification. | Select MLX90372GVS-BCC-201-SP only if 48-bit ID persistence across power cycles and extended diagnostic flags are needed. |
| AMS AS5055A-DSO | SOIC-8 package, 12-bit SPI output only (no analog/PWM), lower operating temp (−40°C to +125°C), no ASIL-B certification. | Suitable for non-safety-critical industrial or consumer linear/rotary encoders where digital interface and cost dominate. | Choose AMS AS5055A-DSO only for non-automotive applications lacking ASIL requirements and where SPI interface suffices. |
Compared with MLX90371GVS-BCC-201-SP, the MLX90372 variant adds persistent programmability at identical form-factor and safety grade, while the AS5055A offers lower-cost SPI-only output but lacks automotive qualification, stray-field immunity, and analog compatibility-making it unsuitable for direct replacement in safety-critical linear position systems.

The MLX90371GVS-BCC-201-SP is configured in Linear Stray-Field Immune Mode, as indicated by the "2" in the BCC-201 option code. This mode optimizes performance for linear displacement sensing while rejecting interfering magnetic fields orthogonal to the primary sensing axis-verified in Section 8.3 of the official datasheet.
Does MLX90371GVS-BCC-201-SP support both analog and PWM outputs simultaneously?
No, MLX90371GVS-BCC-201-SP supports either ratiometric analog or PWM output-not both concurrently. The output type is selected during programming via the USEROPTION_OUTMODE parameter (Section 13.1.1), and the chosen mode persists in NVRAM until reprogrammed.
What package type and lead configuration does MLX90371GVS-BCC-201-SP use?
MLX90371GVS-BCC-201-SP uses the DMP-4 package with STD4 2.54 mm pitch trim-and-form leads (per Section 18.3.4). It has four terminals: two ground (Pins 1 & 4), one supply (Pin 2), and one programmable output (Pin 3).
Is MLX90371GVS-BCC-201-SP certified to ISO26262 ASIL-B?
Yes, MLX90371GVS-BCC-201-SP is certified as an ASIL-B Safety Element out-of-Context (SEooC) per ISO26262-2:2018. This includes documented safety mechanisms (diagnostics, ECC, watchdog), failure modes, and a published safety manual-enabling reuse in ASIL-B system architectures.
What is the maximum latency time for MLX90371GVS-BCC-201-SP in Linear Stray-Field Immune Mode?
The maximum latency time for MLX90371GVS-BCC-201-SP is 462 μs, as specified in Table 9 (General Timing Specification) of the datasheet. This value applies across the full operating temperature range (−40°C to +160°C) and supply voltage (4.5–5.5 V).
