Product details
Overview
MLX90377GVS-ADB-318-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC for absolute rotary or linear position sensing. It delivers 12-bit resolution analog and PWM outputs in High Speed Mode, operates from -40°C to +160°C, supports ratiometric output, and is packaged in DMP-4 for compact PCB-less integration in automotive pedal and throttle position systems.
For engineers reviewing the MLX90377GVS-ADB-318-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed output mode (Analog/PWM High Speed), ISO26262 ASIL-B capability for analog mode, stray-field immune operation in Standard/Legacy configuration, and real-world design meaning for latency, startup timing, and EMC-optimized pin routing.
Technical Context
The MLX90377GVS-ADB-318-RE implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components with on-chip DSP, ADC, and programmable signal conditioning. Its architecture enables absolute angle decoding (0–360°) or linear displacement measurement without mechanical contact using external magnets.
This variant uses Standard/Legacy Mode (-3xx option code) with Analog/PWM High Speed output configuration (ADB-318), fixed at 12-bit resolution, and operates exclusively in DMP-4 package - a PCB-less dual-mold form factor with built-in decoupling capacitors and straight leads per section 19.3.1 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric and PWM (High Speed Mode only); not reprogrammable post-manufacture per ordering code ADB-318. |
| Resolution | 12-bit effective resolution for both analog and PWM outputs, enabling ≤0.1° angular accuracy in 360° full-scale applications. |
| Operating Temp | -40°C to +160°C ambient, validated for under-hood automotive environments including throttle and brake pedal assemblies. |
| Supply Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery-powered, PWM-only); startup threshold is 4.1 V typical. |
| Supply Current | 9–11.5 mA in High Speed Mode (-31x), critical for thermal budgeting in sealed DMP-4 modules with no heatsinking. |
| Latency | Average latency <1.5 ms (typical), defined as magnet movement-to-output response delay; essential for closed-loop control loop stability. |
| Magnetic Range | ±1 T maximum flux density tolerance; supports robust operation in high-stray-field environments without shielding. |
Pinout & Package
DMP-4 package: PCB-less dual-mold construction with integrated decoupling capacitors, 2.54 mm pitch, straight leads (STD1), and footprint compatibility with prior Triaxis® generations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be low-inductance connection to minimize noise coupling into Triaxis® front end. |
| 2 | VDD | Main supply input (4.5–18 V); internal regulator powers all blocks; reverse polarity protected to -14 V. |
| 3 | OUT | Push-pull output supporting ratiometric analog (0.5–99% VDD) or PWM (12-bit duty cycle); drives 5–10 kΩ loads. |
| 4 | VSS | Dedicated ground return path; dual VSS pins reduce ground bounce and improve EMC immunity in noisy automotive harnesses. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous Bx/By/Bz measurement enables true 3D magnetic field decoding for absolute position without mechanical stops or multi-sensor arrays. |
| Programmable Transfer Characteristic | Supports 4- or 8-point piecewise-linear calibration per application; eliminates need for external lookup tables or host MCU compensation. |
| DMP-4 Integrated Decoupling | Built-in capacitors eliminate external bulk capacitance, reducing BOM count and PCB area in space-constrained pedal modules. |
| ISO26262 ASIL-B Compliance | Validated safety element out of context for analog output mode, enabling direct integration into ASIL-B subsystems without additional hardware redundancy. |
| Stray-Field Immunity | Standard/Legacy Mode (-3xx) provides inherent robustness against external magnetic interference common near motors and solenoids. |
Applications
| Pedal Position Sensing | Throttle Position Sensing |
|---|---|
Use Scenario: Non-contact detection of accelerator or brake pedal angular displacement in passenger vehicles and commercial trucks. IC Role / Device Role / Timing Role: Absolute position transducer delivering real-time analog/PWM signals to ECU for torque demand calculation and fail-safe monitoring. Use Value: DMP-4's compact size and integrated decoupling enable direct mounting on pedal arms; 1.5 ms latency ensures responsive engine control during transient maneuvers. |
Use Scenario: Monitoring butterfly valve rotation in gasoline and hybrid powertrains under high-temperature hood conditions. IC Role / Device Role / Timing Role: Primary position feedback device interfacing with engine management system via ratiometric analog or PWM protocol. Use Value: -40°C to +160°C rating and ASIL-B compliance allow single-sensor deployment in safety-critical throttle actuation loops without redundant hardware. |
| Ride Height Control | Steering Wheel Angle Sensing |
Use Scenario: Measuring suspension travel in adaptive air ride systems for vehicle leveling and damping adjustment. IC Role / Device Role / Timing Role: Linear or small-angle position sensor converting suspension displacement into calibrated analog voltage for body control module. Use Value: Stray-field immunity prevents false readings near ABS wheel speed sensors; DMP-4's vibration resistance maintains accuracy over 10M+ cycles. |
Use Scenario: Detecting absolute steering wheel rotation for electronic power steering (EPS) and lane-keeping assist functions. IC Role / Device Role / Timing Role: Safety-relevant angular position source feeding EPS controller with deterministic latency and diagnostic coverage. Use Value: On-chip diagnostics (broken-wire detection on VDD/VSS) and ASIL-B certification reduce system-level validation effort for ISO26262-compliant EPS designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVS-ADB-310-RE | Identical DMP-4 package and High Speed Analog/PWM mode, but lacks the STD2 trim/form (ADB-318 includes Trim & Form STD2 2.54 per section 19.3.2). | Same functional use in pedal/throttle modules; STD2 lead form enables automated placement on tighter-pitch PCBs. | Select ADB-318 when lead geometry must match legacy DMP-4 footprints requiring 2.54 mm STD2 bend profile. |
| MLX90377GDC-ADB-310-RE | SOIC-8 package instead of DMP-4; same -31x output mode and electrical specs, but requires external decoupling and larger board area. | Suitable for prototyping or non-space-constrained ECUs where surface-mount assembly is preferred over PCB-less modules. | Choose SOIC-8 version only if DMP-4's leadless integration or built-in capacitance is not required. |
Compared with MLX90377GVS-ADB-310-RE, the ADB-318 variant adds standardized lead forming for improved SMT yield; versus MLX90377GDC-ADB-310-RE, it trades SOIC-8's assembly flexibility for DMP-4's reduced component count and enhanced mechanical ruggedness in harsh environments.

FAQ
What output protocols does the MLX90377GVS-ADB-318-RE support?
The MLX90377GVS-ADB-318-RE supports only Analog ratiometric and PWM outputs in High Speed Mode, as fixed by its ADB-318 option code. SENT, SPC, and other modes are not available on this specific variant and cannot be enabled via programming - output protocol is factory-configured and immutable.
Is the MLX90377GVS-ADB-318-RE pin-compatible with earlier Triaxis® sensors in DMP-4?
Yes, the MLX90377GVS-ADB-318-RE maintains pin-to-pin compatibility with prior-generation Triaxis® devices in DMP-4 packaging, including identical VSS-VDD-OUT-VSS pinout and mechanical footprint. This allows drop-in replacement in existing pedal and throttle sensor assemblies without PCB redesign.
Does the MLX90377GVS-ADB-318-RE require external decoupling capacitors?
No, the MLX90377GVS-ADB-318-RE in DMP-4 package integrates decoupling capacitors internally, eliminating the need for external bulk capacitance. This reduces bill-of-materials count and PCB area, making it ideal for compact, sealed sensor modules where space and reliability are critical.
What is the startup time for MLX90377GVS-ADB-318-RE in analog mode?
In analog output mode, the MLX90377GVS-ADB-318-RE achieves first valid position output within 3.5 ms after VDD crosses 4.1 V (typical startup threshold). During this interval, the output remains in high-impedance state to prevent erroneous signals from reaching the ECU during power ramp-up.
How does the MLX90377GVS-ADB-318-RE handle broken-wire faults on VDD or VSS?
The MLX90377GVS-ADB-318-RE implements passive broken-wire detection: open VSS pulls OUT to ~1–4% VDD; open VDD pulls OUT to ~92.5–99% VDD. These diagnostic levels are detectable by the host ECU without additional circuitry, satisfying ASIL-B fault coverage requirements for analog mode.
