Product details
Overview
MLX90377GDC-ADB-210-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SOIC-8 package, operating from -40°C to 160°C, delivering 12-bit analog or PWM output with high-speed mode timing (≤100 µs latency), and certified ASIL-B for analog/PWM operation under ISO 26262. It decodes 3D magnetic flux (Bx/By/Bz) for non-contact rotary or linear position sensing in automotive throttle and pedal systems.
For engineers reviewing the MLX90377GDC-ADB-210-SP datasheet, pinout, applications, or equivalent options, this page delivers verified functional specifications, stray-field immune linear-mode configuration, SOIC-8 package interface details, and validated alternative options for automotive position-sensing designs requiring robustness against external magnetic interference.
Technical Context
The MLX90377GDC-ADB-210-SP implements Triaxis® Hall sensing with on-chip DSP and analog-to-digital signal conditioning to resolve absolute angular or linear position from 3-axis magnetic field components. Its Linear Stray-Field Immune Mode (-2xx option code) uses dedicated magnetic front-end calibration and filtering to suppress interference from nearby current-carrying conductors or magnets.
This variant supports only Analog/PWM output (Option Code "1") in High Speed Mode, with startup time ≤100 µs and latency ≤100 µs at 125°C, and operates across 4.5–5.5 V supply with 12–13.5 mA typical supply current. It is not configurable for SENT or SPC output - those require distinct option codes (e.g., -230, -280).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments without derating. |
| Supply Voltage | 4.5 V to 5.5 V - requires regulated supply; battery-mode operation not supported in this variant. |
| Output Modes | Analog ratiometric (0.5–4.5 V) or PWM (10%–90% duty cycle) - fixed at factory; no field reprogramming. |
| Latency | ≤100 µs - enables real-time closed-loop control in fast-response applications like electronic throttle control. |
| Stray-Field Immunity | Linear Stray-Field Immune Mode - calibrated rejection of orthogonal magnetic interference up to ±10 mT. |
| Accuracy | ±0.5° typical angular error over full range - specified for linear motion configurations with optimized magnet placement. |
| ASIL Rating | ISO 26262 ASIL-B capable (analog/PWM mode) - Safety Element out of Context (SEooC) compliant with diagnostic coverage ≥90%. |
Pinout & Package
MLX90377GDC-ADB-210-SP is housed in an 8-pin SOIC-8 package (JEDEC MS-012AC), surface-mountable with 1.27 mm pitch, rated for 175°C junction temperature and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | 4.5–5.5 V regulated supply; internal reverse-polarity and overvoltage protection active. |
| 2 - Input | Test/external measurement port | Factory test access; not intended for end-user signal routing; tie to GND if unused. |
| 3 - Test | Internal test node | Reserved for Melexis production testing; must be connected to VSS per EMC recommendations. |
| 4 - N.C. | No connection | Internally unconnected; recommended to tie to VSS for noise immunity and PCB thermal balance. |
| 5 - OUT | Signal output | Push-pull analog or PWM output; drives 5–10 kΩ load; supports ratiometric scaling to VDD. |
| 6 - N.C. | No connection | Internally unconnected; recommended to tie to VSS for noise immunity and PCB thermal balance. |
| 7 - VDEC | Decoupling capacitor terminal | Requires 100 nF ceramic capacitor to VSS within 2 mm; critical for analog stability and EMC performance. |
| 8 - VSS | Ground reference | Primary return path for analog/digital domains; low-impedance connection required for accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx, By, Bz measurement enables single-chip absolute angle/linear position decoding without external magnets or multi-die 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 |
|---|---|---|---|
| MLX90377GGO-ADB-210-RE | TSSOP-16 dual-die package with isolation resistance >4 MΩ between dies; same Linear Stray-Field Immune Mode and output configuration. | Required for redundant architectures needing die-level fault separation (e.g., ASIL-D decomposition); larger footprint and higher assembly cost. | Select when system-level safety architecture mandates physical isolation between primary and backup channels. |
| MLX90371GDC-ADB-010-SP | Legacy Triaxis® device in SOIC-8; 10-bit resolution, no ASIL support, fixed analog-only output, no programmable linearization. | Suitable for cost-sensitive non-safety applications (e.g., HVAC damper control); lacks stray-field immunity and diagnostic coverage. | Choose only for legacy redesigns where functional safety and magnetic robustness are not required. |
Compared with MLX90377GDC-ADB-210-SP, the TSSOP-16 alternative enables hardware-level redundancy for ASIL-D decomposition, while the MLX90371 offers lower-cost analog-only sensing without safety certification or stray-field rejection - making the MLX90377GDC-ADB-210-SP the optimal choice for new ASIL-B automotive position-sensing designs demanding linear-mode immunity and high-speed responsiveness.

FAQ
What output protocols does the MLX90377GDC-ADB-210-SP support?
The MLX90377GDC-ADB-210-SP supports only analog ratiometric and PWM output modes in High Speed Mode, as defined by its ADB-210 option code. SENT and SPC outputs are not available in this variant - they require separate ordering codes (e.g., -230 or -280) and are factory-programmed, not field-reconfigurable.
Is the MLX90377GDC-ADB-210-SP qualified for automotive under-hood use?
Yes, the MLX90377GDC-ADB-210-SP is AEC-Q100 Grade 0 qualified with guaranteed operation from -40°C to +160°C ambient, junction temperature up to +175°C, and robustness against reverse polarity, overvoltage, and magnetic stray fields - meeting requirements for engine bay and transmission control applications.
Does the MLX90377GDC-ADB-210-SP include functional safety features?
Yes, the MLX90377GDC-ADB-210-SP is ISO 26262 ASIL-B capable for analog and PWM output modes as a Safety Element out of Context (SEooC). It integrates diagnostics including memory ECC, watchdog timers, supply monitoring, and broken-wire detection - all documented in Melexis' certified safety manual.
What is the purpose of the VDEC pin on the MLX90377GDC-ADB-210-SP?
The VDEC pin on the MLX90377GDC-ADB-210-SP is a dedicated decoupling terminal requiring a 100 nF ceramic capacitor connected directly to VSS within 2 mm. It stabilizes the internal analog regulator and reduces noise coupling into the Triaxis® Hall front-end - omission or poor placement degrades accuracy and increases susceptibility to EMI.
Can the MLX90377GDC-ADB-210-SP be used in linear or rotary position sensing?
Yes, the MLX90377GDC-ADB-210-SP supports both linear and rotary absolute position sensing via Triaxis® 3D Hall technology. In Linear Stray-Field Immune Mode, it is optimized for linear stroke applications (e.g., pedal position), but with appropriate magnet geometry and calibration, it also delivers accurate 0–360° rotary measurement per Figure 2 of the datasheet.
