Product details
Overview
MLX90371GVS-BCC-103-RE from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute rotary position output with 12-bit resolution and ±1.5° angular accuracy in Rotary 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 ISO26262 ASIL-B safety elements for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-103-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DMP-4), confirmed pin functions, real-world stray-field immunity behavior, thermal accuracy specs, and direct alternative options for automotive position-sensing designs requiring functional safety compliance.
Technical Context
The MLX90371GVS-BCC-103-RE implements Triaxis® Hall sensing with integrated IMC and 12-bit ADC, enabling contactless absolute angle measurement via magnetic field vector decomposition. Its programmable FIR and exponential moving average filters support configurable latency (440–462 µs) and step response (up to 5.1 ms), while the on-chip DSP enables multi-point linearization (4/8/16/32 segments) and user-defined transfer characteristics.
This variant uses DMP-4 packaging with dual-mold construction and no PCB substrate, features Trim-and-Form STD2 2.54 mm lead configuration, and is factory-programmed for Rotary Stray-Field Immune Mode – Low-Field Variant (BCC-103), delivering robust operation under external magnetic interference up to ±1 mT in-plane gradient.

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-103-RE | Same DMP-4 package and BCC-103 configuration but adds EEPROM-based parameter storage and enhanced diagnostic coverage per ISO26262 ASIL-B requirements. | Required where end-of-line programming or field updates of transfer curves are needed; supports extended diagnostic cycle time (DCT) configurations. | Select MLX90372GVS-BCC-103-RE when firmware-upgradable calibration or higher diagnostic coverage is mandated by OEM safety plan. |
| AMS AS5055A-BQFT | 12-bit contactless angle sensor using integrated Hall array; no on-chip DSP or programmable transfer curve; requires external MCU for linearization. | Used in cost-sensitive industrial controls where ASIL-B compliance is not required and calibration is handled externally. | Choose AMS AS5055A-BQFT only if system architecture already includes host MCU for signal processing and safety monitoring. |
Compared with MLX90371GVS-BCC-103-RE, MLX90372GVS-BCC-103-RE offers field-programmable NVRAM and tighter diagnostic timing control, while AMS AS5055A-BQFT reduces BOM count but shifts safety-critical processing to external silicon - making MLX90371GVS-BCC-103-RE optimal for self-contained, ASIL-B-compliant automotive modules.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-103-RE?
The MLX90371GVS-BCC-103-RE is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range covers under-hood automotive locations including transmission housings and engine manifolds. The device maintains full specification compliance-including angular accuracy, latency, and output linearity-across this entire range without derating or external compensation.
How does the MLX90371GVS-BCC-103-RE achieve stray-field immunity?
The MLX90371GVS-BCC-103-RE achieves stray-field immunity through its factory-programmed BCC-103 configuration, which implements a dedicated algorithmic rejection of in-plane magnetic gradients up to ±1 mT. This mode leverages Triaxis® 3-axis sensing and on-chip DSP to distinguish between useful axial (BZ) field changes and interfering in-plane (BX/BY) fields, eliminating need for external magnetic shielding in applications like chassis-mounted pedal sensors.
Can the MLX90371GVS-BCC-103-RE output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-103-RE supports either ratiometric analog voltage or PWM output-not both simultaneously. Output mode is selected during factory programming and stored in NVRAM; it cannot be changed dynamically in-system. The analog output provides 0–100% VDD swing with 12-bit resolution, while PWM offers 150–2000 Hz frequency with ±5% tolerance, both fully programmable for transfer characteristics and diagnostics.
What package type does the MLX90371GVS-BCC-103-RE use and why is it suitable for automotive applications?
The MLX90371GVS-BCC-103-RE uses the DMP-4 (Dual Mold Package) with STD2 2.54 mm lead pitch. This PCB-less, molded package provides superior thermal conductivity, high vibration resistance, and compact footprint-ideal for space-constrained automotive modules. Its integrated decoupling capacitance simplifies layout, and the dual-mold construction ensures reliability under thermal cycling and humidity exposure per AEC-Q200 standards.
Does the MLX90371GVS-BCC-103-RE require external programming hardware for calibration?
The MLX90371GVS-BCC-103-RE ships pre-programmed with BCC-103 configuration and default transfer characteristics, requiring no external hardware for basic operation. However, end-user calibration (e.g., multi-point linearization, zero-point offset, or diagnostic thresholds) is performed via Melexis' PTC interface using the PTCLink tool and compatible programmer. All calibrated parameters are stored in on-chip NVRAM and persist across power cycles.
