Product details
Overview
MLX90377GDC-ADB-310-TU 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 (≤100 µs latency), ASIL-B functional safety compliance for analog output, and operation from -40°C to +160°C. It decodes 3D magnetic field components (Bx, By, Bz) to enable non-contact rotary or linear position sensing in automotive throttle and pedal systems.
For engineers reviewing the MLX90377GDC-ADB-310-TU datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 pin mapping, real-world use cases in ASIL-B–compliant vehicle subsystems, and validated alternative options for position-sensing designs requiring stray-field robustness and programmable transfer characteristics.
Technical Context
The MLX90377GDC-ADB-310-TU implements Triaxis® Hall front-end architecture with on-chip DSP, ADC, and analog signal conditioner to compute absolute angular or linear position from orthogonal magnetic flux density components. Its high-speed mode (-310 option code) configures internal clock at 22.8 MHz (typ) and achieves ≤100 µs latency with no external filtering.
This variant operates exclusively in Standard/Legacy Mode with analog ratiometric and PWM outputs-no SENT or SPC support-and uses fixed 4-point piecewise-linear transfer characteristic. It lacks dual-die redundancy and isolation features found in TSSOP-16 versions, confirming its single-die SOIC-8 implementation per Table 2 and Section 3.1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric and PWM only; no SENT/SPC-output protocol fixed by ADB-310 option code. |
| Resolution | 12-bit effective resolution for both analog and PWM outputs, enabling 0.088° angular or 0.024% full-scale linear precision. |
| Latency | ≤100 µs in High Speed Mode, critical for closed-loop control in throttle actuation and brake-by-wire response. |
| Operating Temp | -40°C to +160°C junction temperature, qualified for under-hood automotive environments without derating. |
| Supply Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery-powered PWM only), supporting direct vehicle battery interface. |
| Safety Rating | ISO 26262 ASIL-B capable for analog output mode as Safety Element out of Context (SEooC). |
| Magnetic Input | Sensitive to Bx, By, Bz components up to ±1 T; enables absolute position decoding with custom magnet assemblies. |

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-TU | Same SOIC-8 package and Triaxis® core, but Low Power Mode (10 mA typical IDD vs. 11.5 mA for ADB-310); 200 µs latency vs. ≤100 µs. | Used where power budget <12 mA is critical and control loop bandwidth <5 kHz suffices. | Select ADB-300 for battery-powered modules or thermally constrained enclosures where speed is secondary to current draw. |
| MLX90377GGO-ADB-310-TU | TSSOP-16 dual-die package with die-to-die isolation (4 MΩ min), ASIL-C capability, and redundant outputs-physically larger and higher cost. | Required for ASIL-C–rated systems like steer-by-wire; supports full functional redundancy not available in SOIC-8. | Choose ADB-310 in TSSOP-16 only when system-level ASIL-C compliance mandates hardware redundancy and isolation. |
Compared with MLX90377GDC-ADB-300-TU, the MLX90377GDC-ADB-310-TU trades 1.5 mA higher supply current for halved latency-enabling faster control loops-while retaining identical pinout and calibration structure. Against MLX90377GGO-ADB-310-TU, it sacrifices die-level redundancy and ASIL-C qualification to achieve 40% smaller footprint and lower BOM cost in ASIL-B applications.

FAQ
What output protocols does the MLX90377GDC-ADB-310-TU support?
The MLX90377GDC-ADB-310-TU supports analog ratiometric and PWM outputs only, as defined by its ADB-310 option code. SENT and SPC protocols are not available on this variant-output mode is factory-programmed and not reconfigurable in the field. The analog output ranges from 0.5 V to 4.5 V (ratiometric to VDD), while PWM delivers 50–90% duty cycle with 12-bit resolution.
Is the MLX90377GDC-ADB-310-TU pin-compatible with other MLX90377 variants in SOIC-8?
Yes, all MLX90377 variants in SOIC-8 package-including MLX90377GDC-ADB-300-TU and MLX90377GDC-ADB-330-TU-share identical pinout per Section 3.1 of the datasheet. Pin 1 is VDD, Pin 5 is OUT, Pin 7 is VDEC, and Pin 8 is VSS. However, output behavior, latency, and current consumption differ by option code, so electrical validation is required despite mechanical compatibility.
Does the MLX90377GDC-ADB-310-TU require external programming for basic operation?
No, the MLX90377GDC-ADB-310-TU operates immediately after power-up with factory-programmed parameters: High Speed Mode timing, 4-point piecewise-linear transfer characteristic, and analog/PWM dual-output configuration. No end-user programming is needed for standard use-only optional diagnostics or calibration updates require Melexis PTC interface and dedicated tools.
What is the maximum allowable supply voltage for continuous operation of the MLX90377GDC-ADB-310-TU?
The MLX90377GDC-ADB-310-TU supports continuous operation at 4.5 V to 5.5 V when powered by a regulated supply. When using vehicle battery input (for PWM mode only), it tolerates 6 V to 18 V continuously. Absolute maximum ratings permit 28 V for <48 hours and 37 V for <60 seconds-but sustained operation above 18 V risks permanent damage and voids ASIL-B safety certification.
How does stray magnetic field immunity work in the MLX90377GDC-ADB-310-TU?
The MLX90377GDC-ADB-310-TU operates in Standard/Legacy Mode (per ADB-3xx coding), which provides baseline stray-field rejection through differential Triaxis® Hall sensing and on-chip DSP filtering-not the enhanced immunity of -1xx/-2xx/-5xx variants. Its robustness derives from simultaneous Bx/By/Bz measurement and internal compensation algorithms, validated per Section 8.3 for automotive environments with typical EMI sources.
