Product details
Overview
MLX90377GVS-ADB-310-SP 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 4.5–18 V supply, and is packaged in DMP-4 (PCB-less dual mold). It serves as the primary position transducer in automotive throttle and pedal systems.
For engineers reviewing the MLX90377GVS-ADB-310-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package compatibility with legacy Triaxis® sensors, programmable high-speed analog/PWM output, ASIL-B functional safety compliance, and stray-field robustness in standard mode.
Technical Context
The MLX90377GVS-ADB-310-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angle decoding (0–360°) or linear displacement without mechanical contact. Its on-chip DSP performs real-time signal conditioning including 4–32 point piecewise-linearization and configurable filtering.
This variant uses the DMP-4 package (4-pin, PCB-less), implements Standard/Legacy Mode (-3xx code), and configures High Speed Mode for analog/PWM output - delivering faster update rates than Low Power Mode variants while maintaining full ASIL-B capability for analog output per ISO 26262.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit effective resolution for analog and PWM outputs, enabling ±0.1° angular accuracy in typical configurations. |
| Supply Voltage Range | 4.5–18 V DC, supporting direct battery connection (6–18 V) for automotive PWM operation and regulated 5 V for analog use. |
| Operating Temperature | -40°C to +160°C ambient, qualified for under-hood and transmission-mounted applications without derating. |
| Output Modes | Analog ratiometric and PWM only (High Speed Mode); SENT and SPC are disabled per ADB-310 option code. |
| Functional Safety | ISO 26262 ASIL-B capable for analog output mode; Safety Element out of Context (SEooC) certified. |
| Magnetic Sensitivity | Supports detection of magnet positions via orthogonal field components (Bx, By, Bz) with built-in IMC, eliminating need for external concentrators in many layouts. |
| Startup Time | Typical startup time ≤ 5 ms in High Speed Mode, enabling rapid system readiness after power-on in engine control modules. |
Pinout & Package
DMP-4 package: PCB-less dual-mold construction with 4 leads, optimized for compact, high-reliability mounting directly onto flexible substrates or stamped leads. Pin-to-pin compatible with prior-generation Triaxis® DMP-4 sensors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital circuitry; must be low-impedance connection to minimize noise coupling into Triaxis® sensing path. |
| 2 | VDD | Main supply input (4.5–18 V); internal reverse-polarity and overvoltage protection up to -14 V and +37 V for 60 s. |
| 3 | OUT | Configurable analog ratiometric or PWM output; push-pull driver capable of driving 5–10 kΩ loads with <50 Ω Ron. |
| 4 | VSS | Dedicated second ground terminal; improves EMC performance and reduces ground bounce in high-noise environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field decoding for absolute position without rotational ambiguity. |
| Programmable Transfer Characteristic | Up to 32-point piecewise-linear (PWL) calibration allows precise compensation of magnet nonlinearity and mechanical tolerances in final assembly. |
| Stray-Field Immunity (Standard Mode) | Robust operation in presence of external magnetic interference (e.g., nearby motors or solenoids) without hardware shielding or recalibration. |
| Integrated Diagnostics | Built-in broken-wire detection (VDD/VSS open), overtemperature flag, and watchdog timers reduce need for external monitoring circuitry. |
| DMP-4 Mechanical Compatibility | Direct drop-in replacement for legacy MLX90363/MLX90371 DMP-4 variants, preserving board space and lead-frame tooling in production lines. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|
Use Scenario: Real-time detection of accelerator or brake pedal angular displacement in passenger vehicles and commercial trucks. IC Role / Device Role / Timing Role: Primary position transducer converting magnet rotation into high-speed analog/PWM signal for ECU closed-loop torque control. Use Value: 12-bit resolution and ≤5 ms startup enable fast transient response during aggressive pedal actuation, meeting ASIL-B timing constraints. | Use Scenario: Non-contact measurement of linear stroke in electronic brake or clutch pedals with sealed housing requirements. IC Role / Device Role / Timing Role: Absolute linear position sensor interfacing with vehicle stability control (VSC) and regenerative braking systems.

Use Value: ASIL-B certification and dual-ground pins ensure signal integrity in high-EMI steering column environments, reducing diagnostic fault triggers. |
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-300-SP | Same DMP-4 package and Standard Mode, but configured for Low Power Mode analog/PWM output (slower update rate, lower IDD). | Suitable for battery-powered or thermally constrained modules where update rate <1 kHz is acceptable. | Select ADB-300-SP when power budget is tighter and latency tolerance higher; ADB-310-SP preferred for dynamic control loops. |
| MLX90371GVS-ABA-100-SP | Legacy Triaxis® generation in identical DMP-4 package; 10-bit resolution, no SENT/SPC support, fixed 4-point linearization. | Limited to simpler applications without advanced diagnostics or programmable transfer curves. | Choose MLX90371 for cost-sensitive legacy designs; MLX90377GVS-ADB-310-SP adds resolution, flexibility, and ASIL-B compliance. |
Compared with MLX90377GVS-ADB-310-SP, the ADB-300-SP trades speed for lower current draw, while the MLX90371GVS-ABA-100-SP lacks programmable calibration and functional safety certification - making the ADB-310-SP optimal for new ASIL-B-compliant high-dynamics systems.
