Product details
Overview
MLX90371GDC-BCC-200-RE from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute linear position output with 12-bit resolution, ±10° thermal accuracy over –40°C to +160°C, and stray-field immunity in Linear Stray-Field Immune Mode. It operates from 4.5–5.5 V, draws 7–12 mA, and supports programmable ratiometric analog or PWM output for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GDC-BCC-200-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (SOIC-8), confirmed SOIC-8 pin definitions, real-world linear position use cases, and two validated alternative parts with documented functional and application differences.
Technical Context
The MLX90371GDC-BCC-200-RE implements on-chip DSP-based signal processing of triaxial Hall sensor data to compute absolute linear displacement without mechanical contact. Its architecture includes a 12-bit ADC, FIR filter options (FIR1/FIR11/FIR1111), and programmable piecewise-linear transfer characteristic (up to 32 segments) calibrated for linear motion under stray-field conditions.
This variant uses Linear Stray-Field Immune Mode (BCC-200), which configures internal gain, offset, and filtering to reject orthogonal interference fields while maintaining ±10° angular error over temperature. It features ISO 26262 ASIL-B Safety Element out of Context compliance and supports diagnostic functions including broken-wire detection on VDD/VSS and active diagnostics via OUT pin.

Pinout & Package
MLX90371GDC-BCC-200-RE is housed in an SOIC-8 package (8-pin, 150 mil width, gull-wing leads), qualified for reflow soldering and automotive under-hood use. Pin 1 is VDD; pins 4 and 6 are unused; pins 2 and 3 are test-only; pins 5 (OUT), 6 (VSSD), 7 (VDEC), and 8 (VSSA) define core functionality.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | Primary 4.5–5.5 V supply rail; reverse-polarity protected; powers internal regulator and analog/digital blocks. |
| 2 - Test Input | Factory test interface | Used only during wafer sort and final test; must be tied to ground for EMC compliance in end application. |
| 3 - Test | Factory test interface | Internal test access point; no user function; connect to ground for optimal EMC performance. |
| 4 - Not Used | No internal connection | Unbonded die pad; recommended to tie to ground to reduce EMI susceptibility and improve thermal dissipation. |
| 5 - OUT | Signal output | Programmable ratiometric analog or PWM output; push-pull capable; supports 2–10 kΩ load per mode. |
| 6 - VSSD | Digital ground | Dedicated ground return for digital circuitry; separate from analog ground (VSSA) to minimize noise coupling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute linear position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GDC-BCC-200-RE | Same SOIC-8 package and BCC-200 linear mode, but adds integrated EEPROM for factory calibration storage and enhanced diagnostic coverage. | Required where end-of-line calibration data must persist across power cycles without external memory. | Select MLX90372GDC-BCC-200-RE when traceable calibration history or extended diagnostic logging is mandated by OEM specification. |
| AMS AS5600-WSCT | 12-bit rotary encoder IC with I²C interface; no stray-field immunity; no ASIL-B certification; operates at 3.3 V only. | Suitable for non-safety-critical consumer or industrial rotary applications; not qualified for automotive linear position sensing. | Choose AMS AS5600-WSCT only for cost-sensitive, low-EMI rotary designs outside automotive safety domains. |
Compared with MLX90371GDC-BCC-200-RE, MLX90372GDC-BCC-200-RE adds persistent calibration storage but shares identical pinout and linear mode behavior, whereas AMS AS5600-WSCT lacks stray-field rejection, safety certification, and linear motion support-making it unsuitable for automotive pedal or throttle use.

FAQ
What is the operating temperature range of the MLX90371GDC-BCC-200-RE?
The MLX90371GDC-BCC-200-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 such as engine compartments and transmission housings. The device maintains ±10° thermal accuracy across this full span, verified per datasheet Section 9.1.4 for Linear Stray-Field Immune Mode.
Does the MLX90371GDC-BCC-200-RE support both analog and PWM output modes?
Yes, the MLX90371GDC-BCC-200-RE supports both programmable ratiometric analog output and digital PWM output. Output mode selection is configured via on-chip NVRAM programming. Analog mode provides 0–100% VDD output with 12-bit resolution; PWM mode delivers 150–2000 Hz frequency with ±5% tolerance, both fully supported in Linear Stray-Field Immune Mode (BCC-200).
What package type does the MLX90371GDC-BCC-200-RE use?
The MLX90371GDC-BCC-200-RE uses the SOIC-8 package (8-pin, 150 mil width), as indicated by the "DC" code in the ordering part number. This package is RoHS-compliant, qualified for lead-free reflow, and features gull-wing leads compatible with standard SMT assembly processes used in automotive electronics manufacturing.
How does the Linear Stray-Field Immune Mode (BCC-200) differ from Standard Mode?
The BCC-200 option configures the MLX90371GDC-BCC-200-RE with optimized gain, offset, and digital filtering parameters to reject magnetic interference orthogonal to the primary linear motion axis. In contrast, Standard Mode (BCC-300) uses legacy calibration and offers lower stray-field rejection. BCC-200 is validated for linear applications like pedal sensing where nearby solenoids or motors generate disruptive fields.
Is the MLX90371GDC-BCC-200-RE certified for functional safety applications?
Yes, the MLX90371GDC-BCC-200-RE is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC). It integrates hardware diagnostics (memory ECC, watchdog timers), software-configurable diagnostics (broken-wire detection, active pulse diagnostics), and failure mode analysis per its safety manual-enabling integration into ASIL-B systems without requiring additional safety hardware layers.
