Product details
Overview
MLX90377GDC-ADB-330-RE from Melexis is a Triaxis® monolithic magnetic 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 supporting absolute rotary or linear position sensing via Bx/By/Bz field measurement for automotive pedal and throttle applications.
For engineers reviewing the MLX90377GDC-ADB-330-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, SOIC-8 terminal mapping, SENT protocol compliance (SAE J2716 APR2016), ASIL-C safety capability, and real-world use cases in pedal position and ride height sensing.
Technical Context
The MLX90377GDC-ADB-330-RE implements Triaxis® Hall sensing with on-chip DSP, analog-to-digital conversion, and firmware-controlled signal conditioning to decode absolute angular or linear position from three orthogonal magnetic field components (Bx, By, Bz). Its architecture supports programmable transfer characteristics using up to 32-piecewise-linear segments.
This variant is configured exclusively for SENT output mode (3 μs tick time), with no field reprogrammability-output protocol is fixed at manufacture per ADB-330 option code. It operates across 4.5–5.5 V supply (regulated) or 6–18 V (battery), draws 9–11.5 mA, and meets ISO 26262 ASIL-C requirements for SENT operation as a Safety Element out of Context.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT (SAE J2716 APR2016), 3 μs tick time - enables error-coded serial transmission with diagnostic nibbles for ECU-level fault detection. |
| Resolution | 12-bit position data - delivers 0.088° angular resolution over 360° full scale or sub-millimeter linearity in linear configurations. |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments including throttle bodies and brake pedals. |
| Supply Range | 4.5–5.5 V (regulated) or 6–18 V (battery) - supports dual power domains without external regulators in vehicle systems. |
| Current Draw | 9–11.5 mA - optimized for low-power SENT communication while maintaining fast startup and latency performance. |
| Safety Rating | ISO 26262 ASIL-C capable (SENT mode) - certified as Safety Element out of Context for integration into ASIL-D systems with proper decomposition. |
| Magnetic Sensing | Triaxis® Bx/By/Bz measurement - enables robust absolute position decoding without mechanical contact or wear-prone potentiometers. |
Pinout & Package
MLX90377GDC-ADB-330-RE uses the SOIC-8 package (8-pin, 150 mil width, 1.27 mm pitch), with internal decoupling and reverse-polarity protection. Unused pins (N.C., Test) must be tied to ground for EMC compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VDD | Power supply input | Accepts 4.5–18 V; includes reverse-voltage (-14 V) and overvoltage (37 V) protection circuitry. |
| 2: Input | Test/external measurement interface | Used during factory calibration; not intended for end-user signal routing or diagnostics. |
| 3: Test | Internal test access | Dedicated for Melexis production testing; must be grounded per EMC guidelines. |
| 4: N.C. | No connection | Internally unconnected; requires grounding to minimize radiated emissions. |
| 5: OUT | SENT output driver | Push-pull SENT signal output (12-bit frame); compatible with standard automotive SENT receivers. |
| 6: N.C. | No connection | Internally unconnected; requires grounding to minimize radiated emissions. |
| 7: VDEC | Internal regulator decoupling | Must be connected to 100 nF ceramic capacitor to ground for stable analog/digital regulation. |
| 8: VSS | Ground reference | Primary return path for analog, digital, and output stages; low-impedance grounding critical for SENT timing integrity. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic 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, and redundant output capability. | Required for ASIL-D systems needing hardware redundancy; supports independent SENT outputs per die. | Select when functional safety architecture mandates physical separation of sensing paths. |
| MLX90377GVS-ADB-330-RE | DMP-4 package (PCB-less, 4-pin), smaller footprint, integrated decoupling capacitors, and straight or trimmed lead form. | Optimized for space-constrained modules like motorized actuators or compact pedal assemblies. | Select when board area is limited and integrated capacitance simplifies layout. |
Compared with MLX90377GDC-ADB-330-RE, the GO variant adds hardware redundancy for higher ASIL targets, while the VS variant reduces PCB footprint and BOM count via embedded capacitors-neither is pin-compatible, and all three require distinct layout and mechanical integration.

FAQ
What output protocol does the MLX90377GDC-ADB-330-RE support?
The MLX90377GDC-ADB-330-RE is factory-configured exclusively for SENT output with 3 μs tick time per SAE J2716 APR2016. It does not support PWM, analog, or SPC modes-this is fixed by the ADB-330 option code and cannot be changed in the field. The SENT frame includes 12-bit position data, status & communication nibble (SCN), and CRC for error detection.
Is the MLX90377GDC-ADB-330-RE pin-compatible with other MLX90377 variants?
No-the MLX90377GDC-ADB-330-RE uses the SOIC-8 package with 8 pins, while MLX90377GGO-ADB-330-RE uses TSSOP-16 (16 pins) and MLX90377GVS-ADB-330-RE uses DMP-4 (4 pins). Pin count, spacing, and terminal functions differ across packages; each requires unique PCB layout and mechanical mounting.
Does the MLX90377GDC-ADB-330-RE meet automotive functional safety standards?
Yes-the MLX90377GDC-ADB-330-RE is ISO 26262 ASIL-C capable for SENT output mode as a Safety Element out of Context. It includes built-in diagnostics such as memory ECC, watchdog timers, and SENT frame CRC checking. Full ASIL-D compliance requires system-level decomposition with redundant sensing paths.
What is the operating temperature range of the MLX90377GDC-ADB-330-RE?
The MLX90377GDC-ADB-330-RE operates from -40°C to +160°C ambient temperature, with a maximum junction temperature of +175°C. This rating is validated for continuous operation in under-hood environments, including throttle bodies, brake pedals, and suspension modules where thermal cycling and vibration are present.
Can the MLX90377GDC-ADB-330-RE be reprogrammed to change its output mode?
No-the output mode is permanently set during final test by the ADB-330 option code. MLX90377GDC-ADB-330-RE is locked to SENT output and cannot be reconfigured to analog, PWM, or SPC. Reprogramming is only possible for certain calibration parameters (e.g., transfer curve points) using Melexis' PTM tool-not protocol selection.
