Product details
Overview
MLX90371GDC-BCC-300-SP from Melexis is a monolithic Triaxis® position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary or linear position output with 12-bit resolution, ±10-bit thermal accuracy, and programmable ratiometric analog or PWM output in SOIC-8 package. It operates from -40°C to +160°C and supports ISO26262 ASIL-B functional safety as a Safety Element out of Context.
For engineers reviewing the MLX90371GDC-BCC-300-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 pin mapping, real-world use cases in automotive pedal/throttle sensing, and validated alternative options for legacy-mode position sensing designs.
Technical Context
The MLX90371GDC-BCC-300-SP implements on-chip DSP-based signal processing to decode absolute angular or linear position from 3-axis Hall measurements, using internal ADCs, FIR filtering (configurable 1/11/1111 taps), and programmable piecewise-linear transfer functions (up to 32 segments). Its architecture includes integrated voltage regulator, reverse-polarity and overvoltage protection, and dual ground paths (VSSA/VSSD) for analog/digital separation.
This variant operates in Standard/Legacy Mode (BCC-300), delivering 482 µs refresh rate, 462 µs latency, and 150–2000 Hz PWM frequency with ±5% tolerance. It supports 4.5–5.5 V supply, draws 6–10 mA, and features clamped output levels, broken-wire diagnostics, and 48-bit programmable ID storage in NVRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GDC-BCC-300-SP | Same SOIC-8 package and BCC-300 mode, but adds EEPROM-based factory calibration and enhanced EMC filtering. | Preferred for new designs requiring zero-touch calibration and improved radiated immunity in high-noise powertrain zones. | Select MLX90372GDC-BCC-300-SP when production volume justifies higher unit cost for reduced test time and field failure rate. |
| TLE5012BE1000XUMA1 | Infineon GMR-based sensor; 14-bit resolution, 3.3 V supply only, no native PWM output (requires external driver). | Suitable for 3.3 V ECUs with SPI interface; lacks integrated diagnostics and ASIL-B SEooC certification. | Choose TLE5012BE1000XUMA1 only if existing 3.3 V architecture prohibits 5 V devices and SPI communication is preferred over analog/PWM. |
Compared with MLX90371GDC-BCC-300-SP, the MLX90372 offers tighter factory calibration and lower EMC susceptibility, while the TLE5012B requires external level-shifting and diagnostic circuitry - making the MLX90371GDC-BCC-300-SP optimal for cost-sensitive, 5 V, ASIL-B-compliant legacy-mode deployments.

This range supports placement in high-heat zones such as engine compartments, transmission housings, and brake modules where traditional potentiometers fail.
Does the MLX90371GDC-BCC-300-SP support both analog and PWM outputs?
Yes, the MLX90371GDC-BCC-300-SP supports selectable ratiometric analog output (0–100% VDD) or digital PWM output (150–2000 Hz) via end-user programming. The output mode is configured in NVRAM and persists across power cycles, enabling flexible integration with either analog-input or PWM-input ECUs without hardware change.
How is the MLX90371GDC-BCC-300-SP calibrated for different mechanical configurations?
The MLX90371GDC-BCC-300-SP supports multi-point linearization with up to 32 programmable segments stored in on-chip NVRAM. Users configure scaling, zero-degree point, clockwise direction, and clamping limits via Melexis' PTC software tool - eliminating need for host MCU compensation tables and enabling one-time factory calibration per assembly.
What safety certifications apply to the MLX90371GDC-BCC-300-SP?
The MLX90371GDC-BCC-300-SP is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC), with documented fault coverage for memory (ECC), clock monitoring (IWD/AWD), and diagnostic functions. Melexis provides a dedicated safety manual (Rev. 004) covering FMEDA, safety mechanisms, and integration guidance for automotive safety architectures.
Can the MLX90371GDC-BCC-300-SP replace traditional potentiometers directly?
Yes, the MLX90371GDC-BCC-300-SP delivers ratiometric analog output compatible with standard potentiometer interfaces (0–5 V or 0–VDD), requiring only VDD, VSS, and OUT connections. Its SOIC-8 footprint matches common PCB layouts for potentiometer replacements, and its stray-field immunity ensures reliable operation where brushed motors or solenoids generate magnetic noise.
