Product details
Overview
MLX90371GVS-BCC-158-RE from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary position output with 12-bit resolution, ±10° angular accuracy over -40°C to +160°C, and stray-field immunity in Rotary Stray-Field Immune Mode. It supports programmable ratiometric analog or PWM output and integrates on-chip DSP, NVRAM, and thermal compensation for automotive pedal, throttle, and steering wheel sensing.
For engineers reviewing the MLX90371GVS-BCC-158-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed pin functions, real-world accuracy specs under stray-field conditions, functional safety ASIL-B compliance, and validated alternatives for rotary position sensing in harsh environments.
Technical Context
The MLX90371GVS-BCC-158-RE implements Triaxis® Hall sensing with integrated IMC to resolve 3D magnetic vector components, enabling contactless absolute angle measurement without external magnets or gears. Its on-chip DSP performs real-time piecewise-linear interpolation (up to 32 segments) and configurable FIR filtering to suppress mechanical vibration artifacts.
This variant operates exclusively in Rotary Stray-Field Immune Mode with STD4 2.54mm trim-and-form leads (BCC-158), uses internal regulator with VDEC decoupling, and delivers 482 μs refresh rate and 462 μs latency at 18 MHz clock - optimized for fast-response automotive control loops requiring deterministic timing under EMI stress.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-158-RE | Same DMP-4 package and BCC-158 configuration but adds dual-output capability (OUT1 + OUT2) and enhanced ASIL-B diagnostic coverage. | Required where redundant signal paths or higher diagnostic coverage metrics are mandated by system-level ASIL requirements. | Select MLX90372GVS-BCC-158-RE only if dual-output redundancy or extended diagnostic reporting is needed; otherwise MLX90371GVS-BCC-158-RE offers optimal cost/performance balance. |
| AMS AS5055A-BQFT | 14-bit resolution, SPI interface only, no analog/PWM output; requires external MCU for signal conditioning and lacks ASIL-B SEooC certification. | Suitable for board-space-constrained designs where digital interface and higher resolution outweigh need for functional safety compliance. | Choose AMS AS5055A-BQFT when SPI-based host control is preferred and ASIL-B integration effort can be absorbed at system level; not a drop-in replacement. |
Compared with MLX90372GVS-BCC-158-RE, the MLX90371GVS-BCC-158-RE provides identical package, pinout, and stray-field immunity but omits dual-output and advanced diagnostics - reducing BOM cost and firmware complexity. Against AMS AS5055A-BQFT, it trades SPI flexibility for native analog/PWM compatibility, integrated safety, and guaranteed automotive temperature performance without host-side compensation.

The MLX90371GVS-BCC-158-RE is qualified for continuous operation from -40°C to +160°C ambient temperature, with junction temperature up to +175°C. This rating is validated per AEC-Q100 Grade 0 and applies to the DMP-4 package in Rotary Stray-Field Immune Mode (BCC-158), making it suitable for under-hood automotive deployment without thermal derating.
Does MLX90371GVS-BCC-158-RE support both analog and PWM outputs simultaneously?
No, the MLX90371GVS-BCC-158-RE supports either ratiometric analog output or PWM output - selected during programming via its NVRAM configuration. The output mode is fixed after programming and cannot be dynamically switched in runtime. This design ensures deterministic timing behavior and simplifies ECU interface design for MLX90371GVS-BCC-158-RE deployments.
What package type and lead configuration does MLX90371GVS-BCC-158-RE use?
The MLX90371GVS-BCC-158-RE uses the DMP-4 (Dual Mold Package) with 4 terminals and STD4 2.54 mm pitch trim-and-form leads, as defined by the "158" suffix in its option code. This PCB-less package integrates decoupling capacitance and is optimized for direct soldering onto flex or rigid boards in space-constrained automotive modules.
How is stray-field immunity implemented in MLX90371GVS-BCC-158-RE?
MLX90371GVS-BCC-158-RE achieves stray-field immunity through its BCC-158 configuration, which activates a dedicated algorithmic mode that separates useful rotational field components from orthogonal interference using Triaxis® 3D vector analysis and on-chip DSP filtering. This mode is validated for immunity against up to 1 mT stray fields in rotary applications, as specified in Section 8.1 of the MLX90371GVS-BCC-158-RE datasheet.
Is MLX90371GVS-BCC-158-RE certified for functional safety applications?
Yes, the MLX90371GVS-BCC-158-RE is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC). It includes hardware-level safety mechanisms such as memory ECC, lockstep monitoring, and diagnostic test access, enabling its reuse in ASIL-B or ASIL-C systems with appropriate integration validation - a key requirement for MLX90371GVS-BCC-158-RE in automotive control units.
