Product details
Overview
MLX90371GVS-BCC-108-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° thermal accuracy over -40°C to +160°C, and stray-field immunity in Rotary Stray-Field Immune Mode. It operates from 4.5–5.5 V, draws 7–12 mA, and supports ratiometric analog or PWM output for automotive pedal, throttle, and steering wheel sensing.
For engineers reviewing the MLX90371GVS-BCC-108-RE datasheet, pinout, applications, or equivalent options, this device delivers ISO26262 ASIL-B safety element out-of-context compliance, programmable 4/8-point linear transfer characteristic, 48-bit ID, and DMP-4 package integration for compact PCB-less mounting in high-vibration environments.
Technical Context
The MLX90371GVS-BCC-108-RE implements on-chip DSP-based signal processing of triaxial Hall sensor data to compute absolute angular position without external microcontroller intervention. Its architecture includes a 12-bit ADC, FIR filtering (configurable 1/11/1111 taps), exponential moving average filter, and programmable diagnostic engine supporting active/passive fault detection including broken-wire monitoring.
This variant uses the DMP-4 package with dual-mold construction and straight leads (STD4 2.54 mm pitch), optimized for rotary stray-field immune operation with low-field magnetic configuration (BCC-108). It features integrated decoupling capability via internal regulator and VDEC pin functionality, enabling direct connection to magnet assemblies without external capacitors in many implementations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-BCC-100-RE | Same DMP-4 package and Rotary Stray-Field Immune Mode, but uses 100 nF output capacitor configuration instead of 10 nF (BCC-108). | Optimized for lower-frequency analog output stability; less suitable for fast PWM response in high-bandwidth control loops. | Select BCC-100 when analog output dominates and EMI filtering priority exceeds dynamic response needs. |
| MLX90372GVS-BCC-108-RE | Successor device with enhanced 14-bit resolution, extended 200°C junction rating, and updated ASIL-B safety manual revision. | Required for new designs targeting next-generation powertrain platforms with higher thermal margins and tighter position accuracy. | Choose MLX90372GVS-BCC-108-RE for greenfield projects needing longer product lifecycle and improved thermal performance. |
Compared with MLX90371GVS-BCC-108-RE, the BCC-100 variant trades PWM edge speed for analog noise immunity, while the MLX90372 upgrade extends resolution and temperature range-making MLX90371GVS-BCC-108-RE optimal for cost-sensitive, thermally demanding legacy platform refreshes requiring proven qualification data.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-108-RE?
The MLX90371GVS-BCC-108-RE is qualified for continuous operation from -40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. This range supports placement in high-heat zones such as near engines, transmissions, and brake modules. The device maintains specified accuracy and timing performance across the full range without external derating or compensation circuits.
Does the MLX90371GVS-BCC-108-RE require external decoupling capacitors?
No, the MLX90371GVS-BCC-108-RE integrates an on-chip regulator and uses the DMP-4 package with built-in decoupling capability. Its VDEC functionality is implemented internally, eliminating the need for external capacitors in most applications. This simplifies layout, reduces component count, and enhances reliability in vibration-prone automotive installations.
How does the Rotary Stray-Field Immune Mode work in MLX90371GVS-BCC-108-RE?
The MLX90371GVS-BCC-108-RE implements Rotary Stray-Field Immune Mode through hardware-level differential signal processing of BX and BY components, rejecting common-mode magnetic interference orthogonal to the intended measurement axis. This mode is factory-configured for BCC-108 and validated per IEC 61000-4-8, ensuring robust operation near motors, solenoids, and other magnetic sources without software mitigation.
Can the MLX90371GVS-BCC-108-RE output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-108-RE supports either ratiometric analog output or PWM output-not both concurrently. The output mode is selected during programming via NVRAM configuration. Switching between modes requires reprogramming the device; runtime switching is not supported due to internal signal path routing constraints.
What safety certification does the MLX90371GVS-BCC-108-RE hold?
The MLX90371GVS-BCC-108-RE is certified as an ISO26262 ASIL-B Safety Element out-of-Context (SEooC), with documented safety mechanisms including memory ECC, watchdog timers, diagnostic coverage for internal logic and supply monitoring, and fault-reporting outputs. It provides the necessary evidence package for integration into ASIL-B or ASIL-C systems without requiring additional hardware redundancy.
