Product details
Overview
MLX90371GDC-BCC-100-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 compliance for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GDC-BCC-100-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 package details, real-world use cases in ride height and steering wheel sensing, and validated alternative options for functional replacement in high-reliability automotive systems.
Technical Context
The MLX90371GDC-BCC-100-RE implements a Triaxis® Hall sensor architecture with integrated ADC, digital signal processor (DSP), and firmware-controlled output stage. Its core function is decoding absolute angular position from rotating magnets using programmable multi-point linearization (4/8-point LNR or 16/32-segment PWL) and configurable stray-field immunity algorithms optimized for low-field rotary applications.
It features dual ground paths (VSSA/VSSD), on-chip voltage regulator with VDEC decoupling, reverse polarity and overvoltage protection, and programmable diagnostics including broken-wire detection. The device uses internal 18 MHz clock with ±3% thermal drift and delivers latency of 462 μs and step response up to 5.1 ms depending on FIR filter configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - Operates within standard automotive 5 V rail tolerance; includes reverse-polarity and overvoltage protection up to -14 V and +45 V. |
| Operating Temperature | -40°C to +160°C - Qualified for under-hood automotive environments including engine bay and transmission control units. |
| Output Resolution | 12-bit - Delivers 4096 discrete angular positions across 0–360°, enabling sub-degree position granularity in closed-loop control. |
| Angular Accuracy | ±1.5° - Validated for Rotary Stray-Field Immune Mode (BCC-100); ensures reliable pedal/throttle feedback despite external magnetic interference. |
| Latency Time | 462 μs - Critical for real-time torque estimation and fast-response vehicle dynamics control loops. |
| PWM Frequency Range | 150–2000 Hz - Configurable for ECU compatibility; 1 kHz default enables deterministic timing with ±5% stability over temperature. |
| Power Consumption | 7–12 mA - Enables low-power operation in battery-sensitive modules without compromising update rate or diagnostic coverage. |
Pinout & Package
MLX90371GDC-BCC-100-RE is housed in an 8-pin SOIC-8 package (JEDEC MS-012AC) with gull-wing leads, 1.27 mm pitch, and exposed die pad for thermal management. Pin 1 is marked with a dot; recommended PCB layout connects unused pins (Pin 2, Pin 3, Pin 4) to ground for optimal EMC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – VDD | Primary supply input | Accepts 4.5–5.5 V; powers analog front-end, DSP, and output stage; requires local 100 nF decoupling. |
| 2 – Test Input | Factory test interface | Unused in end application; must be tied to VSS per datasheet for EMC robustness. |
| 3 – Test | Factory test interface | No user-accessible function; tie to VSS to prevent noise coupling into sensitive analog circuitry. |
| 4 – Not Used | Reserved pad | No internal connection; connect to VSS to reduce EMI susceptibility and improve thermal conduction. |
| 5 – OUT | Programmable output | Delivers ratiometric analog (0–100% VDD) or PWM signal; supports 5 kΩ pull-up/pull-down loads. |
| 6 – VSSD | Digital ground | Reference for output stage and digital logic; separate from analog ground to minimize switching noise injection. |
| 7 – VDEC | On-chip regulator decoupling | Connects to 100 nF capacitor to stabilize internal 3.3 V regulator; critical for ADC and DSP stability. |
| 8 – VSSA | Analog ground | Reference for Hall sensors, ADC, and analog signal path; isolate from VSSD at PCB level for best INL performance. |

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 |
|---|---|---|---|
| MLX90372GDC-BCC-100-RE | Same SOIC-8 package and BCC-100 mode, but adds 16-bit resolution and extended -40°C to +175°C junction rating. | Required for next-gen powertrain ECUs demanding higher angular precision and extended thermal margin beyond 160°C ambient. | Select when design requires >12-bit resolution or operation above 160°C ambient; otherwise MLX90371GDC-BCC-100-RE remains optimal cost/performance choice. |
| AMS AS5055A-BQFT | 14-bit SPI-output magnetic encoder; no integrated PWM/analog output; requires external MCU for signal conditioning. | Suitable for designs with available microcontroller resources and where digital interface simplifies ECU integration over analog/PWM. | Choose if system already uses SPI-based sensor fusion and can accommodate external processing; avoid if direct analog/PWM replacement of potentiometers is mandatory. |
Compared with MLX90372GDC-BCC-100-RE, the MLX90371GDC-BCC-100-RE offers lower BOM cost and proven qualification for existing ASIL-B platforms, while AMS AS5055A-BQFT shifts signal processing burden to the host MCU but eliminates need for on-chip linearization programming.

How does the MLX90371GDC-BCC-100-RE achieve stray-field immunity in rotary applications?
The MLX90371GDC-BCC-100-RE achieves stray-field immunity through proprietary Triaxis® signal processing that separates useful in-plane rotation signals (BX/BY) from interfering orthogonal fields (BZ) and applies adaptive filtering tuned specifically for low-field rotary configurations. This allows it to maintain ±1.5° accuracy even when exposed to external magnetic fields up to ±1 mT from adjacent actuators or motors.
What package type is used by the MLX90371GDC-BCC-100-RE?
The MLX90371GDC-BCC-100-RE uses an SOIC-8 package (package code "DC"), measuring 4.9 mm × 6.0 mm × 1.75 mm with gull-wing leads and 1.27 mm pitch. It includes an exposed die pad for thermal dissipation and is compatible with standard reflow soldering profiles per J-STD-020.
Is the MLX90371GDC-BCC-100-RE certified to ISO26262 standards?
Yes, the MLX90371GDC-BCC-100-RE is certified as an ASIL-B Safety Element out-of-Context per ISO26262-5:2018, with documented safety mechanisms including lock-step CPU monitoring, memory ECC, voltage/temperature watchdogs, and diagnostic coverage exceeding 90%.
