Product details
Overview
MLX90377GDC-ADB-310-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SOIC-8 package, delivering 12-bit analog and PWM outputs with high-speed mode timing (≤100 µs latency), ±0.5° angular accuracy over -40°C to +160°C, and robust stray-field immunity for automotive throttle and pedal position sensing.
For engineers reviewing the MLX90377GDC-ADB-310-RE datasheet, pinout, applications, or equivalent options, this page delivers verified functional specifications, SOIC-8 terminal mapping, safety-critical output behavior, and validated alternatives for ASIL-B–capable analog/PWM position sensing in harsh environments.
Technical Context
The MLX90377GDC-ADB-310-RE implements Triaxis® Hall front-end sensing of Bx, By, and Bz magnetic components to compute absolute rotary or linear position without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (4/8/16/32 points) and configurable filtering for dynamic response tuning.
This variant operates exclusively in Standard/Legacy Mode with analog ratiometric and PWM outputs enabled in High Speed Mode (−310 option code), achieving ≤100 µs latency and 12-bit resolution. It is not SENT-, SPC-, or stray-field-immune-mode capable - those require −330, −380, −2xx, or −5xx option codes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric (0–VDD) and PWM (duty cycle proportional to position); no SENT/SPC support in this variant |
| Resolution | 12-bit effective resolution for both analog and PWM outputs, enabling 0.088° angular step resolution over 360° |
| Latency | ≤100 µs typical in High Speed Mode (−310), critical for real-time closed-loop control in throttle actuation |
| Accuracy | ±0.5° total angular error over full temperature range (−40°C to +160°C), including INL, DNL, and thermal drift |
| Supply Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery-powered, PWM-only); reverse voltage protection to −18 V |
| Operating Temp | −40°C to +160°C ambient, junction-rated to +175°C - qualified for under-hood automotive placement |
| Safety Rating | ISO 26262 ASIL-B capable for analog output mode; not ASIL-C rated in this configuration |
Pinout & Package
MLX90377GDC-ADB-310-RE 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 integrated decoupling support and EMC-robust pin assignment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Main power supply input | Accepts 4.5–18 V; internal regulators derive analog/digital rails; reverse polarity protected |
| 2 - Input | Test/external measurement interface | Factory test access; not intended for end-user signal routing; tie to GND if unused |
| 3 - Test | Internal diagnostic/test node | Reserved for Melexis production testing; must be connected to VSS per datasheet for EMC compliance |
| 4 - N.C. | No connection | Internally unconnected; recommended to tie to VSS for noise suppression |
| 5 - OUT | Primary output terminal | Delivers ratiometric analog voltage (0–VDD) or PWM signal; push-pull drive, 50 Ω typical Ron |
| 6 - N.C. | No connection | Internally unconnected; recommended to tie to VSS for noise suppression |
| 7 - VDEC | Decoupling capacitor connection | Requires external 100 nF ceramic capacitor to VSS; critical for analog stability and EMI reduction |
| 8 - VSS | Ground reference | System ground return; connects to internal analog/digital grounds; low-impedance path required |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Measures Bx, By, Bz simultaneously to resolve absolute angle or linear displacement without magnet rotation constraints |
| Programmable Transfer Curve | Supports 4-, 8-, 16-, or 32-point piecewise-linear calibration to match custom mechanical travel profiles |
| High-Speed Analog/PWM Output | ≤100 µs latency enables use in fast-response systems like electronic throttle control (ETC) and brake-by-wire interfaces |
| ASIL-B Safety Capability | Includes built-in diagnostics (broken-wire detection, watchdog, CRC) meeting ISO 26262 requirements for analog output mode |
| Stray-Field Immunity (Legacy Mode) | Robust against external magnetic interference up to ±1 T via on-chip IMC and differential signal processing |

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-RE | Same SOIC-8 package and Triaxis® core, but configured for Low Power Mode (≥500 µs latency, 8 mA IDD) | Optimized for battery-powered or thermally constrained modules where latency <100 µs is not required | Select when system timing budget allows slower response and lower current draw is prioritized over speed |
| MLX90377GGO-ADB-310-RE | Identical electrical functionality and timing, but in TSSOP-16 dual-die package with isolation (4 MΩ inter-die resistance) | Required for ASIL-C–level redundancy schemes where die-level fault separation is mandated | Choose only when full hardware redundancy and inter-die isolation are explicitly required by safety architecture |
Compared with MLX90377GDC-ADB-310-RE, the −300 variant trades latency for power efficiency, while the GO-packaged −310 provides physical die separation for higher ASIL integrity - neither offers SENT/SPC or stray-field immune modes, preserving identical functional scope for legacy analog/PWM designs.

FAQ
What output protocols does the MLX90377GDC-ADB-310-RE support?
The MLX90377GDC-ADB-310-RE supports only analog ratiometric (0–VDD) and PWM output modes in High Speed configuration. It does not support SENT, SPC, or stray-field immune modes - those require different option codes (e.g., −330 for SENT, −210 for linear stray-field immunity). This variant is factory-programmed and cannot be reconfigured in the field.
Is the MLX90377GDC-ADB-310-RE pin-compatible with earlier Triaxis® sensors?
Yes - the MLX90377GDC-ADB-310-RE in SOIC-8 package maintains pin-to-pin compatibility with prior-generation Melexis Triaxis® position sensors (e.g., MLX90363, MLX90364) using the same DC package code. Pin assignments for VDD, VSS, OUT, and VDEC match exactly, enabling drop-in replacement in existing layouts without redesign.
What is the maximum operating temperature and thermal derating for MLX90377GDC-ADB-310-RE?
The MLX90377GDC-ADB-310-RE is rated for −40°C to +160°C ambient operation, with junction temperature limited to +175°C. No thermal derating is required within this range; all specifications - including ±0.5° accuracy and ≤100 µs latency - are guaranteed across the full interval per datasheet Table 10 and Section 9.4.
Does MLX90377GDC-ADB-310-RE include built-in diagnostics for functional safety compliance?
Yes - the MLX90377GDC-ADB-310-RE integrates multiple diagnostics required for ISO 26262 ASIL-B compliance in analog output mode, including broken-wire detection (VDD/VSS monitoring), watchdog timers, CRC-protected NVRAM, and self-test routines. These are enabled by default and do not require external configuration.
Can MLX90377GDC-ADB-310-RE be used with a 12 V battery supply?
Yes - the MLX90377GDC-ADB-310-RE accepts 6–18 V battery-supply inputs, but analog output operation is only specified under regulated 4.5–5.5 V conditions. For 12 V direct connection, PWM output mode must be selected (per datasheet Section 6), and external regulation or filtering is required to maintain analog accuracy and stability.
