Product details
Overview
MLX90371GGO-BCC-100-RE from Melexis is a Triaxis® monolithic position processor IC that measures all three orthogonal magnetic field components (BX, BY, BZ) to deliver absolute rotary position output with 12-bit resolution and ±10-bit thermal accuracy. It operates from -40°C to +160°C, supports programmable ratiometric analog or PWM output, and implements stray-field immunity for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GGO-BCC-100-RE datasheet, pinout, applications, or equivalent options, this device requires attention to its DMP-4 package footprint, rotary stray-field immune mode configuration, ISO26262 ASIL-B safety element out-of-context compliance, and programmable multi-point linearization for precision angular measurement in harsh environments.
Technical Context
The MLX90371GGO-BCC-100-RE uses integrated magnetic concentrators and on-chip DSP to decode absolute angle from rotating magnets without mechanical contact. Its architecture includes a 12-bit ADC, FIR filtering (configurable up to 4-stage), and dual-path signal processing for analog and PWM outputs.
This variant is configured for Rotary Stray-Field Immune Mode – Low-Field Variant (BCC-100), requiring ≤25 mT in-plane field (BX/BY) and ≥100 mT axial field (BZ). It features programmable 4/8-point linearization or 16/32-segment piecewise-linear transfer characteristics and supports diagnostic functions including broken-wire detection and intelligent watchdog.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GGO-BCC-100-RE | Same DMP-4 package and BCC-100 mode, but adds EEPROM-based calibration storage and enhanced diagnostic coverage. | Required where end-of-line calibration data must be retained without host MCU intervention. | Select MLX90372GGO-BCC-100-RE if factory-programmed calibration persistence is mandatory; otherwise MLX90371GGO-BCC-100-RE suffices for host-managed calibration. |
| AMS AS5055A-BQFT | 14-bit resolution, SPI interface only, no native PWM output; requires external microcontroller for signal conditioning. | Suitable for designs with existing SPI infrastructure and software-defined output formatting. | Choose AMS AS5055A-BQFT only when higher resolution is critical and host MCU resources are available for real-time linearization and diagnostics. |
Compared with MLX90371GGO-BCC-100-RE, the MLX90372GGO-BCC-100-RE adds non-volatile calibration retention but increases cost and complexity, while the AMS AS5055A-BQFT offers higher resolution at the expense of requiring external processing and lacking native functional safety certification.

FAQ
What is the magnetic field requirement for MLX90371GGO-BCC-100-RE in Rotary Stray-Field Immune Mode?
The MLX90371GGO-BCC-100-RE requires ≤25 mT in-plane magnetic field (BX/BY) and ≥100 mT axial field (BZ) for optimal performance in Rotary Stray-Field Immune Mode. This configuration enables robust operation in environments with stray fields up to ±10 mT while maintaining <0.3° angular error. The device's internal DSP rejects common-mode interference without external shielding.
Does MLX90371GGO-BCC-100-RE require an external decoupling capacitor?
No, MLX90371GGO-BCC-100-RE does not require an external decoupling capacitor. Its DMP-4 package integrates VDEC functionality directly into the VDD pin, eliminating the need for a discrete 100 nF capacitor. This simplifies layout, reduces BOM count, and improves reliability in space-constrained automotive modules where the MLX90371GGO-BCC-100-RE is commonly deployed.
How is functional safety implemented in MLX90371GGO-BCC-100-RE?
MLX90371GGO-BCC-100-RE implements ISO26262 ASIL-B Safety Element out-of-Context (SEooC) through on-chip diagnostics including memory ECC, clock monitoring, watchdog timers (IWD/AWD), and broken-wire detection on VDD and VSS pins. These mechanisms are validated per Melexis safety manual and enable integration into ASIL-B systems without additional hardware-level redundancy.
Can MLX90371GGO-BCC-100-RE output both analog and PWM signals simultaneously?
No, MLX90371GGO-BCC-100-RE supports either ratiometric analog or PWM output-not both simultaneously. The output mode is selected during programming via NVRAM configuration. Analog mode provides 0–100% VDD output with 12-bit resolution and 200 V/ms slew rate; PWM mode delivers 150–2000 Hz pulses with ±5% frequency tolerance and configurable duty cycle mapping.
What package type and pin count does MLX90371GGO-BCC-100-RE use?
MLX90371GGO-BCC-100-RE uses the DMP-4 (Dual Mold Package) with 4 terminals: VSS (Pin 1), VDD (Pin 2), OUT (Pin 3), and VSS (Pin 4). This PCB-less, surface-mount package measures 3.2 mm × 2.5 mm and is designed for direct soldering onto flexible or rigid substrates in compact automotive sensors where the MLX90371GGO-BCC-100-RE serves as the core position processor.
