Product details
Overview
MLX90371GVS-BCC-303-RE from Melexis is a Triaxis® monolithic position processor IC that senses all three orthogonal magnetic field components (BX, BY, BZ) to deliver absolute rotary or linear position output with 12-bit resolution and ±10-bit thermal accuracy. It operates from -40°C to +160°C, supports programmable ratiometric analog or PWM output, and implements ISO26262 ASIL-B Safety Element out of Context for automotive pedal, throttle, and steering applications.
For engineers reviewing the MLX90371GVS-BCC-303-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DMP-4), confirmed pin functions, real-world stray-field immune operation in Standard/Legacy mode, and validated alternatives for position-sensing system design.
Technical Context
The MLX90371GVS-BCC-303-RE uses integrated magnetic concentrators and on-chip DSP to decode absolute angular or linear displacement from magnet motion, with internal ADC, FIR filtering, and programmable transfer characteristics (4/8-point LNR or 16/32-segment PWL). Its DMP-4 package embeds decoupling capacitance and enables PCB-less mounting.
This variant implements Standard/Legacy mode-backward-compatible with prior-generation MLX903xx devices-with fixed magnetic sensitivity, no stray-field immunity enhancement, and default 12-bit analog/PWM output scaling. It features reverse-polarity and overvoltage protection, integrated temperature sensing, and NVRAM-programmable diagnostics including broken-wire detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - Operates within standard automotive 5 V rail tolerance; supports robust start-up at 3.95 V. |
| Supply Current | 6–10 mA - Low quiescent current enables use in battery-sensitive systems like ride height sensors. |
| Output Type | Ratiometric analog or PWM - Configurable per application: analog for potentiometer replacement, PWM for noise-immune ECU interfacing. |
| Resolution & Accuracy | 12-bit output with ±10-bit thermal accuracy - Delivers <±0.1° angular error over full -40°C to +160°C range in calibrated systems. |
| Latency Time | 440–462 µs - Enables real-time closed-loop control in fast-response applications such as electronic throttle control. |
| PWM Frequency | 150–2000 Hz - Adjustable for ECU sampling constraints; 1 kHz default balances resolution and response time. |
| Operating Temperature | -40°C to +160°C - Qualified for under-hood automotive environments without external cooling or derating. |
| Safety Certification | ISO26262 ASIL-B SEooC - Provides documented safety mechanisms (diagnostics, watchdog, ECC memory) for functional safety integration. |
Pinout & Package
DMP-4 (Dual Mold Package) - 4-pin, PCB-less surface-mount module with built-in decoupling capacitance; designed for direct soldering onto flexible substrates or metal leads. Dimensions: 3.2 × 2.5 × 1.0 mm (STD4 2.54 mm lead pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be connected to low-impedance chassis ground for EMC compliance. |
| 2 | VDD | Primary supply input (4.5–5.5 V); includes reverse-polarity and overvoltage protection up to -14 V / +45 V. |
| 3 | OUT | Programmable output terminal: drives ratiometric analog voltage (0–100% VDD) or PWM signal (150–2000 Hz). |
| 4 | VSS | Second ground terminal - electrically tied internally; improves thermal dissipation and reduces ground loop impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous BX/BY/BZ measurement enables true 360° absolute angle decoding without mechanical stops or multi-die assemblies. |
| Programmable Transfer Characteristic | Supports 4/8-point linearization or 16/32-segment piecewise-linear curves - eliminates external calibration hardware in production. |
| Stray-Field Immunity (Legacy Mode) | Standard/Legacy mode (BCC-303) retains baseline robustness against external magnetic interference without requiring special magnet configurations. |
| Integrated Diagnostics | Real-time broken-wire detection (VDD/VSS open), active diagnostic pulses, and configurable fault reporting reduce system-level validation effort. |
| DMP-4 Embedded Decoupling | On-module 100 nF capacitor eliminates need for external bulk capacitance - simplifies layout and improves high-frequency noise rejection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-303-RE | Same DMP-4 package and pinout; adds enhanced stray-field immunity and extended magnetic range in Rotary/Legacy modes. | Required where EMI environment exceeds legacy spec (e.g., near high-current inverters or solenoids). | Select MLX90372GVS-BCC-303-RE only if new designs require improved robustness; not drop-in for existing MLX90371 layouts due to firmware differences. |
| MLX90363KGO-ABA-000-SP | TSSOP-16 package with dual-die isolation; supports higher channel count but lacks DMP-4's PCB-less form factor. | Suitable for dual-axis or redundant single-axis systems needing die-to-die isolation per ISO26262 ASIL-D decomposition. | Choose MLX90363KGO-ABA-000-SP when functional safety architecture mandates physical separation - not for space-constrained DMP-4 footprints. |
Compared with MLX90371GVS-BCC-303-RE, MLX90372GVS-BCC-303-RE offers upgraded stray-field resilience without changing board layout, while MLX90363KGO-ABA-000-SP provides certified die isolation at the cost of larger footprint and no embedded capacitance - making MLX90371GVS-BCC-303-RE optimal for cost- and size-sensitive legacy-mode deployments.

The MLX90371GVS-BCC-303-RE is qualified for continuous operation from -40°C to +160°C ambient temperature, matching AEC-Q100 Grade 0 requirements. This rating applies to its DMP-4 package and is validated across all electrical parameters including supply current, output accuracy, and latency - enabling direct use in under-hood locations without thermal derating.
Does the MLX90371GVS-BCC-303-RE support both analog and PWM outputs?
Yes, the MLX90371GVS-BCC-303-RE supports either ratiometric analog voltage (0–100% VDD) or programmable PWM output (150–2000 Hz), selected via on-chip NVRAM configuration. The analog mode interfaces directly with ECU ADC inputs; the PWM mode provides noise-immune digital signaling compatible with standard microcontroller capture timers.
What does "BCC-303" signify in MLX90371GVS-BCC-303-RE?
In MLX90371GVS-BCC-303-RE, "BCC-303" identifies the die version: "3" indicates Standard/Legacy mode (backward-compatible with earlier MLX903xx devices), "0" specifies 100 nF embedded output capacitance, and "3" denotes STD2 2.54 mm lead-form configuration per Melexis package documentation.
Is the MLX90371GVS-BCC-303-RE certified for automotive functional safety?
Yes, the MLX90371GVS-BCC-303-RE is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC). It includes hardware-level diagnostics (broken-wire detection, watchdog timer, ECC-protected NVRAM), documented safety mechanisms, and a dedicated safety manual - enabling integration into ASIL-B or decomposed ASIL-C/D systems.
Can the MLX90371GVS-BCC-303-RE be used without an external decoupling capacitor?
Yes - the DMP-4 package of MLX90371GVS-BCC-303-RE integrates a 100 nF ceramic capacitor between VDD and VSS, eliminating the need for external decoupling. This is confirmed in Melexis' recommended application diagrams and package specification documents, reducing bill-of-materials and PCB area in compact sensor modules.
