Product details
Overview
MLX90371GDC-BCC-100-SP 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 and throttle sensing.
For engineers reviewing the MLX90371GDC-BCC-100-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOIC-8), confirmed pin functions, ISO26262 ASIL-B safety compliance, programmable transfer characteristics, and real-world use cases in high-reliability automotive motion sensing.
Technical Context
The MLX90371GDC-BCC-100-SP implements on-chip DSP with FIR filtering (configurable 1/11/1111 taps) and exponential moving average filtering to suppress noise while maintaining latency as low as 440 μs. Its Triaxis® architecture uses integrated magnetic concentrators to resolve 3D flux vectors, enabling robust angle decoding without external magnets or shielding in rotary configurations.
It features dual ground paths (VSSA analog, VSSD digital), on-die voltage regulation via VDEC decoupling pin, reverse polarity and overvoltage protection up to ±14 V on VDD, and programmable diagnostics including broken-wire detection on VDD/VSS and active diagnostic signaling on OUT.

Pinout & Package
MLX90371GDC-BCC-100-SP is housed in an SOIC-8 package (8-pin, 150 mil width, 1.27 mm pitch), with exposed pad option not specified. Pin 1 is VDD; pins 2 and 3 are test inputs; pin 5 is the primary output; pins 6 and 8 are dedicated ground terminals (VSSD and VSSA); pin 7 is VDEC for internal regulator decoupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – VDD | Power supply input | Primary 4.5–5.5 V supply; includes reverse-polarity and overvoltage protection up to -14 V / +45 V. |
| 2 – Test Input | Factory test interface | Used during wafer sort and final test; recommended to tie to VSS for EMC stability in end application. |
| 3 – Test | Factory test interface | Internal test access node; no functional role in operation; tie to VSS per datasheet recommendation. |
| 5 – OUT | Programmable output | Configurable ratiometric analog (0–100% VDD) or PWM (150–2000 Hz); push-pull capable up to ±30 mA. |
| 6 – VSSD | Digital ground | Return path for digital core and output stage; separate from analog ground to minimize noise coupling. |
| 7 – VDEC | Regulator decoupling | Connect 100 nF capacitor to VSS for stable internal LDO operation; critical for output accuracy and EMC performance. |
| 8 – VSSA | Analog ground | Return path for Hall sensor front-end and ADC; must be star-connected to VSSD at single point near IC. |

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-100-SP | Same SOIC-8 package and pinout; adds 16-bit resolution, improved ±2° thermal accuracy, and enhanced ASIL-B diagnostic coverage. | Targeted at next-gen ADAS and steer-by-wire systems requiring tighter angular tolerance and extended safety case depth. | Select MLX90372 when higher resolution and lower thermal error are mandatory; MLX90371GDC-BCC-100-SP remains optimal for cost-sensitive ASIL-B pedal/throttle modules. |
| AMS AS5055A-BQFT | 14-bit resolution, SPI interface only (no analog/PWM), requires external MCU for processing; no built-in stray-field immunity or ASIL-B certification. | Suitable for non-safety-critical industrial encoders or consumer robotics where host processing and layout control are available. | Choose AMS AS5055A-BQFT only if SPI interface and external computation are acceptable; MLX90371GDC-BCC-100-SP delivers autonomous, certified output with minimal system overhead. |
Compared with MLX90372GDC-BCC-100-SP, the MLX90371GDC-BCC-100-SP trades resolution and thermal accuracy for lower BOM cost and proven qualification in high-volume automotive programs; versus AMS AS5055A-BQFT, it provides direct analog/PWM output, integrated safety mechanisms, and guaranteed stray-field immunity without layout dependency.

FAQ
What is the operating temperature range of the MLX90371GDC-BCC-100-SP?
The MLX90371GDC-BCC-100-SP 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 throttle bodies and brake pedals, where ambient temperatures exceed 125°C. The device maintains its ±10° thermal accuracy specification across this full range in Rotary Stray-Field Immune Mode.
Does the MLX90371GDC-BCC-100-SP support both analog and PWM output simultaneously?
No, the MLX90371GDC-BCC-100-SP supports either ratiometric analog output or PWM output-not both concurrently. The output mode is configured permanently in NVRAM during programming and cannot be changed dynamically in operation. The analog output provides 0–100% VDD swing with 12-bit resolution; the PWM output offers 150–2000 Hz frequency with ±5% tolerance and configurable duty cycle mapping.
Is the MLX90371GDC-BCC-100-SP pin-compatible with other MLX90371 variants in SOIC-8 package?
Yes, all MLX90371 variants in SOIC-8 package-including MLX90371GDC-BCC-100-SP, MLX90371GDC-BCC-200-SP, and MLX90371GDC-BCC-300-SP-share identical pinout, footprint, and electrical interface. Differences lie solely in factory-programmed firmware settings (e.g., stray-field mode, transfer curve, and diagnostic behavior), not hardware connectivity or timing.
What is the purpose of the VDEC pin on the MLX90371GDC-BCC-100-SP?
The VDEC pin on the MLX90371GDC-BCC-100-SP serves as the decoupling terminal for the internal voltage regulator. A 100 nF ceramic capacitor must be placed between VDEC and VSS to stabilize the on-die LDO, ensuring accurate analog output, low-noise DSP operation, and robust EMC performance. Omitting or misplacing this capacitor degrades thermal accuracy and increases susceptibility to supply ripple.
How does the MLX90371GDC-BCC-100-SP achieve ISO26262 ASIL-B compliance?
The MLX90371GDC-BCC-100-SP achieves ISO26262 ASIL-B compliance as a Safety Element out of Context (SEooC), meaning it provides documented safety mechanisms-including internal watchdogs, memory ECC, diagnostic cycles, and broken-wire detection-without requiring external hardware redundancy. Its safety manual (Rev. 004) defines fault coverage, diagnostic test intervals, and safe states, enabling seamless integration into ASIL-B systems like electronic throttle control.
