Product details
Overview
MLX90377GDC-ADB-280-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC in SOIC-8 package, delivering 12-bit SPC (Short PWM Code) output with 1.5 μs tick time, operating from -40 °C to +160 °C, and certified ASIL-B for analog/PWM and ASIL-C for SENT/SPC modes. It enables absolute rotary or linear position sensing in automotive pedal, throttle, and ride height systems using stray-field immune magnetic configurations.
For engineers reviewing the MLX90377GDC-ADB-280-RE datasheet, pinout, applications, or equivalent options, key selection considerations include its Linear Stray-Field Immune Mode (-2xx), SPC protocol compliance, SOIC-8 thermal performance, and functional safety qualification per ISO 26262.
Technical Context
The MLX90377GDC-ADB-280-RE implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components, enabling absolute angle or linear displacement decoding without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable filtering for noise robustness in harsh EMI environments.
This variant uses Linear Stray-Field Immune Mode (Option Code ADB-280), which optimizes magnetic sensitivity and immunity for linear motion applications such as float-level or small-stroke sensors. It operates exclusively in SPC output mode with fixed 1.5 μs tick time and cannot be reprogrammed to other protocols post-manufacture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SPC (Short PWM Code) with 1.5 μs tick time - enables deterministic low-latency communication compatible with automotive ECUs requiring short-pulse timing. |
| Operating Temperature | -40 °C to +160 °C - supports under-hood and transmission-mounted applications without external thermal derating. |
| Supply Voltage Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - accommodates both stable rail and direct vehicle battery input with reverse polarity protection. |
| Functional Safety | ISO 26262 ASIL-C capable for SPC output - qualifies as Safety Element out of Context (SEooC) for system-level ASIL-D architectures. |
| Magnetic Sensing | Triaxis® 3-axis Hall front-end - resolves absolute position from magnet motion without requiring multi-die redundancy or external signal conditioning. |
| Accuracy | ±0.5° typical angular error in Linear Stray-Field Immune Mode - ensures high-fidelity feedback for closed-loop control of throttle or suspension actuators. |

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-280-RE | TSSOP-16 dual-die package with isolation resistance >4 MΩ between dice; higher pin count and larger footprint. | Required where full redundancy (ASIL-D) is mandated; supports independent diagnostics per die. | Select when functional safety architecture demands hardware redundancy beyond SEooC qualification. |
| MLX90377GVS-ADB-280-RE | DMP-4 package (PCB-less dual mold); 4-pin, 2.54 mm pitch; no VDEC pin; integrated decoupling capacitors. | Suitable for space-constrained modules where board area is limited and external caps are undesirable. | Choose for compact actuator-integrated designs needing simplified layout and reduced BOM count. |
Compared with MLX90377GDC-ADB-280-RE, the TSSOP-16 variant adds physical redundancy at the cost of board area and routing complexity, while the DMP-4 version trades pin flexibility and decoupling control for miniaturization and integration - all three share identical SPC timing, stray-field immunity, and ASIL-C capability.
