Product details
Overview
MLX90377GVS-ADB-303-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC for absolute rotary or linear position sensing. It delivers 12-bit ratiometric analog and PWM outputs in Standard/Legacy Mode, operates from -40°C to 160°C, features stray-field immunity in legacy configuration, and is used in automotive throttle and pedal position sensing.
For engineers reviewing the MLX90377GVS-ADB-303-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), output protocol constraints (analog/PWM only, not reprogrammable), ASIL-B safety capability, and validated alternative options for non-contacting position sensing designs.
Technical Context
The MLX90377GVS-ADB-303-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, a 12-bit ADC, DSP-based signal processing engine, and dual-output stage supporting ratiometric analog and PWM. Its DMP-4 package embeds decoupling capacitors and uses straight leads with 2.54 mm pitch.
This variant implements Standard/Legacy Mode (-3xx option code) with low-power operation, fixed analog/PWM output selection (not SENT/SPC), and programmable linear transfer characteristic using 4- or 8-point piecewise-linear interpolation. It does not support full redundancy or dual-die isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric and PWM only; SENT/SPC disabled per ADB-303 option code - no field reconfiguration possible. |
| Resolution | 12-bit effective resolution for both analog and PWM outputs - enables 0.1° angular or 0.025% full-scale linear position accuracy. |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments including transmission and engine control modules. |
| Supply Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - supports direct vehicle battery connection with reverse polarity protection. |
| Supply Current | 8–11.5 mA in Legacy Mode - optimized for low-power ECU subsystems without compromising update rate. |
| Magnetic Sensing | Triaxis® 3-axis Hall front end - enables absolute position decoding from single moving magnet in rotary (0–360°) or linear configurations. |
| Safety Rating | ISO 26262 ASIL-B capable for analog output mode - certified Safety Element out of Context (SEooC) for functional safety integration. |
Pinout & Package
DMP-4 package: PCB-less dual-mold construction with integrated decoupling capacitors, 4-pin SMT footprint, 2.54 mm lead pitch, STD2 trim and form (ADB-303 suffix), RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains - must be connected to system ground plane for EMC compliance. |
| 2 | VDD | Main supply input - accepts 4.5–18 V; internal regulator powers core logic and analog front end. |
| 3 | OUT | Configurable dual-mode output - delivers either ratiometric analog voltage (0.5–4.5 V) or PWM (10–90% duty cycle) based on factory programming. |
| 4 | VSS | Second ground terminal - improves thermal dissipation and reduces ground loop impedance in high-noise environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Sensing | Enables true absolute position measurement from a single magnet without mechanical cam or gear - eliminates wear and hysteresis in throttle/pedal linkages. |
| Programmable Transfer Curve | Supports 4- or 8-point piecewise-linear calibration - allows precise linearization for custom magnetic circuits without external lookup tables. |
| Stray-Field Immunity (Legacy) | Robust operation in high-EMI zones (e.g., near motors or solenoids) without shielding - validated per ISO 11452-8. |
| Integrated Decoupling | DMP-4 package includes embedded ceramic capacitors - eliminates need for external bulk capacitance and saves PCB area in space-constrained modules. |
| Reverse Polarity Protection | Withstands -14 V reverse supply for <1 h - prevents damage during battery jump-start or wiring errors in production assembly. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|
Use Scenario: Monitoring accelerator pedal angle in gasoline/diesel powertrain control units to determine torque demand. IC Role / Device Role / Timing Role: Absolute angular position transducer interfacing directly to ECU ADC or PWM capture peripheral with 10 kHz update rate.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-ADB-303-SP | Single-die Triaxis® sensor with identical DMP-4 package, same analog/PWM output modes, but limited to 10-bit resolution and no ASIL-B certification. | Lower-cost option for non-safety-critical industrial position feedback where ±1° accuracy suffices. | Select when functional safety compliance is not required and BOM cost reduction is prioritized over resolution and diagnostic coverage. |
| TLV493DW2B6HTSA1 | Infineon 3D Hall sensor in TSSOP-16; offers I²C digital output, 12-bit resolution, but no analog/PWM native support and no ASIL-B qualification. | Suitable for microcontroller-based systems with available I²C resources and software-defined signal conditioning. | Choose when digital interface flexibility and lower quiescent current (2.5 µA sleep) outweigh need for direct ECU analog/PWM compatibility. |
Compared with MLX90377GVS-ADB-303-SP, MLX90371GVS-ADB-303-SP trades ASIL-B compliance and 12-bit precision for cost, while TLV493DW2B6HTSA1 replaces analog/PWM immediacy with digital configurability - neither matches the exact combination of DMP-4 integration, stray-field resilience, and safety-certified analog/PWM output in this variant.

FAQ
What output protocols does the MLX90377GVS-ADB-303-SP support?
The MLX90377GVS-ADB-303-SP supports only ratiometric analog voltage and PWM outputs, as defined by its ADB-303 option code. SENT and SPC protocols are disabled in this variant and cannot be enabled via programming - output mode is factory-fixed and non-reconfigurable in the field.
Is the MLX90377GVS-ADB-303-SP qualified for automotive under-hood use?
Yes, the MLX90377GVS-ADB-303-SP is rated for -40°C to +160°C operation and qualified to AEC-Q100 Grade 0. Its DMP-4 package includes built-in decoupling capacitors and reverse polarity protection, making it suitable for direct mounting in engine compartments, transmission control units, and brake modules.
Does the MLX90377GVS-ADB-303-SP require external decoupling capacitors?
No, the MLX90377GVS-ADB-303-SP in DMP-4 package integrates ceramic decoupling capacitors internally. External capacitors are not required for stable operation - this reduces PCB footprint and eliminates solder joint reliability risks associated with discrete capacitor placement near the IC.
What is the functional safety status of the MLX90377GVS-ADB-303-SP?
The MLX90377GVS-ADB-303-SP is ISO 26262 ASIL-B capable for analog output mode as a Safety Element out of Context (SEooC). It includes diagnostic features such as broken-wire detection on VDD/VSS and configurable watchdog timers, with safety manual and FMEDA documentation provided by Melexis.
Can the MLX90377GVS-ADB-303-SP be used in rotary or linear position sensing?
Yes, the MLX90377GVS-ADB-303-SP supports both rotary (0–360°) and linear position measurement using appropriate magnet configurations. Its Triaxis® architecture senses all three magnetic field vector components (Bx, By, Bz), enabling absolute position decoding without mechanical cams or gears in either geometry.
