Product details
Overview
MLX90377GDC-ADB-330-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SOIC-8 package, delivering 12-bit SENT output with 3 μs tick time, operating from -40°C to +160°C, and certified ASIL-C capable for safety-critical automotive pedal and throttle position sensing.
For engineers reviewing the MLX90377GDC-ADB-330-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional context, SOIC-8 pin mapping, SENT protocol timing compliance (SAE J2716 APR2016), ASIL-C safety architecture, and validated automotive-grade alternatives.
Technical Context
The MLX90377GDC-ADB-330-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling robust absolute angular or linear position decoding without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and real-time stray-field immunity in Standard/Legacy Mode.
This variant is factory-configured for SENT output only (ADB-330 code), with fixed 3 μs tick time, no field reprogramming capability, and operates exclusively in Standard/Legacy magnetic configuration. It uses a single-die SOIC-8 package with integrated analog regulator, reverse-polarity protection, and overvoltage protection up to 37 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SAE J2716 APR2016-compliant SENT with 3 μs tick time - enables deterministic, error-coded digital position reporting compatible with automotive ECUs. |
| Resolution | 12-bit position data - delivers 0.088° angular resolution over 360° or sub-millimeter linear precision in calibrated systems. |
| Operating Temp | -40°C to +160°C - supports under-hood automotive placement without external thermal derating. |
| Supply Range | 4.5 V to 18 V - accommodates both regulated 5 V supplies and direct vehicle battery connection (with PTC entry at 6.55 V). |
| Supply Current | 9–11.5 mA (typ.) - optimized for low-power SENT operation while maintaining full ASIL-C diagnostic coverage. |
| Safety Certification | ISO 26262 ASIL-C capable (SENT mode) - includes built-in diagnostics, watchdog timers, memory ECC, and fault-handling time interval ≤ 100 ms. |
| Magnetic Sensitivity | ±1 T maximum flux density - supports high-strength magnet configurations while rejecting common-mode stray fields. |
Pinout & Package
MLX90377GDC-ADB-330-SP uses the SOIC-8 surface-mount package (8-pin, 3.9 mm × 4.9 mm, 1.27 mm pitch), designed for automotive PCB assembly and high-temperature reflow. Unused pins (N.C., Test) must be connected to ground per Melexis EMC recommendations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – VDD | Power supply input | Accepts 4.5–18 V; includes reverse-polarity and overvoltage protection; powers internal analog/digital regulators. |
| 2 – Input | Test/external measurement interface | Factory test access point; not intended for end-user signal routing; recommended tied to GND in production. |
| 3 – Test | Internal test node | Reserved for Melexis wafer-level testing; must be connected to VSS per datasheet for optimal EMC. |
| 4 – N.C. | No connection | Internally unconnected; electrically isolated; requires grounding per EMC guidelines. |
| 5 – OUT | Digital SENT output driver | Push-pull SENT signal output (12-bit frame); supports 3 μs tick time; compliant with SAE J2716 APR2016. |
| 6 – N.C. | No connection | Internally unconnected; electrically isolated; requires grounding per EMC guidelines. |
| 7 – VDEC | Decoupling capacitor terminal | Connects to 100 nF ceramic capacitor near VDD to suppress high-frequency noise on internal digital regulator. |
| 8 – VSS | Ground reference | Primary return path for analog/digital circuits; critical for accurate SENT timing and stray-field rejection. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall sensing | Simultaneous Bx, By, Bz measurement enables true absolute position decoding from rotating or linear magnets without mechanical stops or gears. |
| Programmable transfer characteristic | Up to 32-point piecewise-linear calibration allows precise linearization of non-ideal magnet trajectories - essential for throttle and pedal applications. |
| SENT output with diagnostics | Embedded CRC, status nibbles, and configurable error codes provide real-time integrity checking and fault classification for ASIL-C systems. |
| Stray-field immunity (Standard Mode) | Robust operation in magnetically noisy environments (e.g., near motors or solenoids) without external shielding or compensation algorithms. |
| Integrated safety mechanisms | Includes watchdog timers, memory ECC, voltage/temperature monitoring, and fail-safe high-impedance output - all required for ISO 26262 ASIL-C compliance. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GGO-ADB-330-RE | TSSOP-16 dual-die package with inter-die isolation (>4 MΩ); higher pin count; supports full redundancy. | Required for ASIL-D systems or where hardware redundancy is mandated; occupies larger PCB area; needs two decoupling networks. | Select when functional safety requires physical separation between redundant channels or when legacy TSSOP-16 footprint is fixed. |
| MLX90377GVS-ADB-330-RE | DMP-4 package (PCB-less, 4-pin); 2.54 mm pitch; no exposed leads; optimized for direct magnet mounting. | Ideal for space-constrained linear actuators or compact rotary modules where SOIC-8 height or thermal mass is prohibitive. | Choose for ultra-low-profile integration into mechatronic assemblies or where board-level assembly is avoided via direct die bonding. |
Compared with MLX90377GDC-ADB-330-SP, the TSSOP-16 variant adds hardware redundancy at the cost of size and layout complexity, while the DMP-4 version trades SOIC-8 compatibility for minimal form factor and simplified mechanical integration - neither is pin-compatible, but all share identical SENT protocol, timing, and calibration behavior.

The MLX90377GDC-ADB-330-SP is factory-configured exclusively for SENT output per SAE J2716 APR2016 with 3 μs tick time. It does not support PWM, analog, or SPC modes - the ADB-330 option code permanently selects SENT, and output protocols cannot be changed post-manufacture.
Is the MLX90377GDC-ADB-330-SP qualified for automotive under-hood use?
Yes, the MLX90377GDC-ADB-330-SP is rated for -40°C to +160°C ambient operation and qualified to AEC-Q100 Grade 0. Its SOIC-8 package, integrated overvoltage protection (up to 37 V), and reverse-polarity hardening make it suitable for direct engine bay mounting in throttle, pedal, and suspension control units.
Does the MLX90377GDC-ADB-330-SP support functional safety standards?
Yes, the MLX90377GDC-ADB-330-SP is ISO 26262 ASIL-C capable in SENT mode as a Safety Element out of Context (SEooC). It includes built-in diagnostics, memory ECC, watchdog timers, and fault-handling mechanisms documented in Melexis' safety manual (Rev. 003).
Can the MLX90377GDC-ADB-330-SP be reprogrammed for different transfer characteristics?
Yes - though output mode is fixed, the MLX90377GDC-ADB-330-SP retains full end-user programmability for transfer characteristics (4/8/16/32-point PWL), filtering, diagnostics, and magnetic front-end settings via Melexis' PTC interface and PTCLink software, using the VDD pin for programming voltage elevation.
What is the pin configuration of the MLX90377GDC-ADB-330-SP?
The MLX90377GDC-ADB-330-SP uses an SOIC-8 package with confirmed pinout: Pin 1 = VDD, Pin 2 = Input, Pin 3 = Test, Pin 4 = N.C., Pin 5 = OUT (SENT), Pin 6 = N.C., Pin 7 = VDEC, Pin 8 = VSS. All N.C. and Test pins must be grounded per Melexis EMC guidelines.
