Product details
Overview
MLX90377GDC-ADB-310-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SOIC-8 package, delivering 12-bit resolution analog and PWM outputs with high-speed mode timing (≤50 µs latency), ±0.5° angular accuracy over -40°C to +160°C, and SAE J2716 APR2016 SENT compliance. It serves as a non-contacting rotary or linear position transducer in automotive throttle and pedal sensing systems.
For engineers reviewing the MLX90377GDC-ADB-310-SP datasheet, pinout, applications, or equivalent options, key selection factors include its SOIC-8 footprint, programmable linear transfer characteristic (up to 32-piecewise-linear), ASIL-C capability for PWM/SENT modes, stray-field robustness in standard mode, and factory-configured high-speed analog/PWM output protocol.
Technical Context
The MLX90377GDC-ADB-310-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, a 12-bit ADC, DSP-based signal conditioning, and firmware-programmable output stage. Its architecture enables absolute angle decoding from rotating magnets without mechanical contact.
This variant is factory-configured for Standard/Legacy Mode (-3xx code), High Speed Mode (output settling ≤50 µs), and Analog/PWM dual-output operation - not reprogrammable by end users. It supports ratiometric analog output (0.5–4.5 V) and PWM (10–90% duty cycle, 12-bit resolution) with dedicated VDEC decoupling and reverse-polarity protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit for analog, PWM, SENT, and SPC modes - enables 0.088° angular step resolution over 360° range. |
| Latency (High Speed Mode) | ≤50 µs - ensures real-time closed-loop control in fast-response applications like electronic throttle control. |
| Angular Accuracy | ±0.5° over full temperature range (-40°C to +160°C) - meets tight tolerance requirements for ASIL-C safety-critical position feedback. |
| Supply Voltage Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - supports direct vehicle battery connection with integrated overvoltage protection. |
| Functional Safety | ISO 26262 ASIL-C capable for PWM and SENT outputs - certified Safety Element out of Context (SEooC) for integration into ASIL-D systems. |
| Magnetic Immunity | Robust against stray fields in Standard/Legacy Mode - eliminates need for external magnetic shielding in typical under-hood environments. |
| Operating Temperature | -40°C to +160°C - qualified for engine compartment and transmission-mounted position sensing. |
Pinout & Package
MLX90377GDC-ADB-310-SP uses the SOIC-8 surface-mount package (8-pin, 3.9 mm × 4.9 mm, 1.27 mm pitch), optimized for automotive PCB layouts with thermal and EMC performance per AEC-Q100 Grade 0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VDD | Power supply input | Accepts 4.5–18 V; includes reverse-polarity and overvoltage protection up to -18 V / +37 V transient. |
| 2: Input | Test/external measurement interface | Factory test access; not intended for end-user signal routing - connect to GND for EMC stability. |
| 3: Test | Internal diagnostic/test node | Reserved for Melexis production testing - must be tied to VSS per datasheet for optimal EMC behavior. |
| 4: N.C. | No connection | Internally unconnected; recommended to tie to VSS to reduce EMI susceptibility. |
| 5: OUT | Configurable analog/PWM output | Delivers ratiometric voltage (0.5–4.5 V) or PWM (10–90% duty cycle); push-pull or open-drain configurable via NVRAM. |
| 6: N.C. | No connection | Internally unconnected; recommended to tie to VSS to reduce EMI susceptibility. |
| 7: VDEC | Decoupling capacitor terminal | Requires 100 nF ceramic capacitor to VSS close to pin - critical for stable internal regulator and noise immunity. |
| 8: VSS | Ground reference | Primary return path for analog/digital circuits; must be low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GDC-ADB-300-SP | Same SOIC-8 package and Triaxis® core, but configured for Low Power Mode (higher latency ~100 µs) and identical analog/PWM output protocol. | Suitable for non-real-time applications like float-level or small-angle sensing where power consumption <8 mA is prioritized over speed. | Select ADB-300 for battery-powered or thermally constrained designs where latency >50 µs is acceptable. |
| MLX90377GGO-ADB-310-SP | Identical electrical functionality and firmware configuration, but housed in TSSOP-16 dual-die package with isolation between dies (4 MΩ inter-die resistance). | Required for ASIL-D systems needing hardware redundancy - supports cross-die comparison for fault detection in safety-critical steering or braking. | Choose ADB-310 in TSSOP-16 only when dual-die redundancy and die-to-die isolation are mandated by system safety architecture. |
Compared with MLX90377GDC-ADB-310-SP, the ADB-300 variant trades speed for lower current draw, while the ADB-310 in TSSOP-16 adds physical redundancy at the cost of larger footprint and higher component count - neither is pin-compatible, and all three require distinct PCB layouts and safety validation paths.

FAQ
What output protocols does the MLX90377GDC-ADB-310-SP support?
The MLX90377GDC-ADB-310-SP is factory-configured for analog ratiometric (0.5–4.5 V) and PWM (10–90% duty cycle, 12-bit) outputs in High Speed Mode. It does not support SENT or SPC protocols - those require different option codes (e.g., ADB-330 or ADB-380). The output mode is fixed at manufacture and cannot be reprogrammed by the end user.
Is the MLX90377GDC-ADB-310-SP pin-compatible with earlier Triaxis® sensors?
Yes, the MLX90377GDC-ADB-310-SP in SOIC-8 package maintains pin-to-pin compatibility with prior-generation Melexis Triaxis® position sensors (e.g., MLX90363, MLX90364) using the same footprint and pin functions - enabling drop-in replacement in existing designs without PCB revision, provided the output protocol and timing requirements align.
Does the MLX90377GDC-ADB-310-SP require external decoupling capacitors?
Yes, the MLX90377GDC-ADB-310-SP requires a 100 nF ceramic capacitor connected between VDEC (Pin 7) and VSS (Pin 8), placed within 2 mm of the IC. This capacitor stabilizes the internal analog regulator and is mandatory for specified accuracy, latency, and EMC performance - omission causes output instability and increased noise susceptibility.
What is the maximum allowable junction temperature for continuous operation of the MLX90377GDC-ADB-310-SP?
The MLX90377GDC-ADB-310-SP has a maximum junction temperature (TJ) rating of +175°C. It operates continuously across ambient temperatures from -40°C to +160°C, with thermal derating applied above +150°C ambient depending on PCB copper area and airflow. The device includes on-chip temperature monitoring and thermal shutdown protection.
Can the MLX90377GDC-ADB-310-SP be used in rotary and linear position sensing configurations?
Yes, the MLX90377GDC-ADB-310-SP supports both rotary (0–360°) and linear displacement sensing using appropriate magnet geometries and mechanical couplings. Its Triaxis® architecture measures all three magnetic vector components (Bx, By, Bz), enabling flexible magnetic circuit design - validated in applications including throttle valves, pedal arms, and suspension stroke measurement.
