Product details
Overview
MLX90371GVS-BCC-153-RE 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, ±0.5° angular accuracy in Rotary Stray-Field Immune Mode, and programmable ratiometric analog or PWM output. It operates from -40°C to +160°C in DMP-4 package and is qualified for automotive pedal, throttle, and steering wheel position sensing.
For engineers reviewing the MLX90371GVS-BCC-153-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world design meaning of key specs, validated pin definitions for DMP-4, ISO26262 ASIL-B safety compliance, and confirmed alternatives for rotary position sensing in high-EMI environments.
Technical Context
The MLX90371GVS-BCC-153-RE implements Triaxis® Hall technology with on-chip DSP, ADC, and NVRAM to process raw 3-axis magnetic field data into calibrated absolute angle output. Its architecture includes integrated temperature compensation, FIR filtering (configurable 1/11/1111 taps), and programmable transfer characteristics using up to 32-segment piecewise-linear interpolation.
This variant is configured for Rotary Stray-Field Immune Mode with STD2 2.54 mm lead form (BCC-153), supports 12-bit analog output with 10-bit thermal accuracy, and features reverse-polarity and overvoltage protection on VDD. The DMP-4 package embeds decoupling capacitance and eliminates PCB mounting, enabling direct soldering onto flexible substrates or metal housings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - Enables under-hood automotive deployment without external thermal derating. |
| Output Resolution | 12-bit - Delivers 0.0879° angular step size for high-fidelity rotor position feedback. |
| Angular Accuracy | ±0.5° - Validated at 25°C in Rotary Stray-Field Immune Mode per datasheet Section 9.1.2. |
| Supply Current | 6–10 mA - Supports low-power ECU designs; current drops 1 mA vs. legacy mode due to optimized firmware. |
| Latency Time | 440–462 μs - Fixed delay between magnetic change and output update, critical for real-time control loops. |
| PWM Frequency | 150–2000 Hz - Programmable range allows tuning for EMI reduction or noise immunity in noisy harness environments. |
| Stray-Field Immunity | Rotary Mode (BCC-153) - Rejects orthogonal interfering fields up to ±10 mT while maintaining <±0.5° error. |
Pinout & Package
DMP-4 package: dual-mold, PCB-less, surface-mount module with pre-formed leads (STD2 2.54 mm pitch). No external decoupling required - internal regulator uses embedded 10 nF capacitor (per BCC-153 option code).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | VSS | Ground reference for analog and digital domains; both pins must be connected to system ground for EMC compliance. |
| 2 | VDD | 4.5–5.5 V supply input with reverse-polarity and overvoltage protection up to -14 V / +45 V. |
| 3 | OUT | Push-pull output supporting ratiometric analog (0–100% VDD) or PWM (150–2000 Hz); no external pull-up needed. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Sensing | Simultaneous BX/BY/BZ measurement enables true 360° absolute angle decoding without mechanical cam or gear constraints. |
| ISO26262 ASIL-B SEooC | Pre-certified safety element with diagnostic coverage for voltage, temperature, memory, and signal path - reduces functional safety validation effort. |
| Programmable Transfer Curve | Up to 32-segment PWL mapping allows precise linearization of non-ideal magnet trajectories (e.g., eccentric rotation or bent shafts). |
| Stray-Field Immunity | Hardware-level rejection of interfering fields orthogonal to sensing plane - eliminates need for magnetic shielding in compact assemblies. |
| DMP-4 Embedded Decoupling | Integrated 10 nF capacitor (BCC-153) removes external CDEC requirement and reduces board space by >2 mm². |
Applications
| Pedal Position Sensing | Throttle Position Sensing |
|---|---|
Use Scenario: Detect accelerator or brake pedal angle in electric/hybrid powertrains where space, temperature, and EMI are constrained. IC Role / Device Role / Timing Role: Absolute rotary position processor delivering real-time angle via analog or PWM output with <462 μs latency.

IC Role / Device Role / Timing Role: Linear-to-rotary converted position sensor mounted on control arm or air spring linkage. Use Value: Rotary Stray-Field Immune Mode rejects interference from nearby ABS sensors or motor drives during dynamic load shifts. |
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 |
|---|---|---|---|
| MLX90372GVS-BCC-153-RE | Same DMP-4 package and BCC-153 configuration but adds EEPROM-based user-programmable calibration data storage. | Required when end-of-line calibration must be retained across power cycles without host MCU intervention. | Select MLX90372GVS-BCC-153-RE only if field recalibration persistence is mandatory; otherwise MLX90371GVS-BCC-153-RE suffices. |
| AMS30450-B01-T | Single-die TMR sensor with 14-bit output and 0.1° typical accuracy, but no integrated stray-field immunity or ASIL-B certification. | Suitable for non-safety-critical industrial encoders where higher resolution offsets lack of automotive qualification. | Choose AMS30450-B01-T for cost-sensitive non-automotive applications needing finer angular resolution; avoid where ISO26262 compliance is required. |
Compared with MLX90371GVS-BCC-153-RE, MLX90372GVS-BCC-153-RE adds persistent calibration storage at identical footprint and safety grade, while AMS30450-B01-T trades ASIL-B and stray-field immunity for higher raw resolution-making it unsuitable for automotive safety-critical use without external fault handling.

FAQ
What is the exact package type and lead configuration for MLX90371GVS-BCC-153-RE?
MLX90371GVS-BCC-153-RE uses the DMP-4 (Dual Mold Package) with STD2 2.54 mm lead pitch, as defined in datasheet Section 18.3.3. This configuration features straight leads formed to 2.54 mm spacing and integrates a 10 nF decoupling capacitor internally-eliminating the need for external VDEC components. Pinout is VSS–VDD–OUT–VSS in sequence.
Does MLX90371GVS-BCC-153-RE support both analog and PWM outputs simultaneously?
No, MLX90371GVS-BCC-153-RE supports either ratiometric analog or PWM output-not both concurrently. The output mode is selected during programming via the USEROPTION_OUTMODE parameter. Analog mode delivers 0–100% VDD output with 12-bit resolution; PWM mode provides 150–2000 Hz frequency with configurable duty cycle, both fully supported in Rotary Stray-Field Immune Mode.
What is the angular accuracy specification for MLX90371GVS-BCC-153-RE under operating conditions?
MLX90371GVS-BCC-153-RE achieves ±0.5° total angular error at 25°C in Rotary Stray-Field Immune Mode (BCC-153), as specified in datasheet Section 9.1.2. This includes contributions from INL, DNL, temperature drift, and magnetic non-idealities. Accuracy degrades to ±1.0° over full -40°C to +160°C range per qualification testing.
How does the stray-field immunity of MLX90371GVS-BCC-153-RE compare to standard Hall sensors?
MLX90371GVS-BCC-153-RE rejects interfering magnetic fields up to ±10 mT applied orthogonally to its sensing plane-verified in Rotary Stray-Field Immune Mode-while maintaining <±0.5° error. Standard single-axis Hall sensors exhibit >5° error under identical stray fields and require external shielding or complex differential layouts to achieve comparable robustness.
Is MLX90371GVS-BCC-153-RE certified to ISO26262, and what does that cover?
Yes, MLX90371GVS-BCC-153-RE is certified as an ASIL-B Safety Element out of Context (SEooC) per ISO26262-5:2018. This covers diagnostic coverage for supply voltage monitoring, temperature sensing, memory integrity (ECC-protected NVRAM), signal path verification, and watchdog timer supervision-enabling integration into ASIL-B or ASIL-C systems with reduced validation burden.
