Product details
Overview
MLX90377GDC-ADB-300-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SOIC-8 package, delivering ratiometric analog or PWM output with 12-bit resolution, -40°C to +160°C operating range, and ASIL-B functional safety compliance for analog mode. It decodes rotary (0–360°) or linear displacement via Bx/By/Bz magnetic field sensing in automotive pedal, throttle, and steering applications.
For engineers reviewing the MLX90377GDC-ADB-300-SP datasheet, pinout, applications, or equivalent options, this page delivers verified SOIC-8 pin mapping, low-power analog/PWM timing specs, stray-field immune configuration limits, SENT/SPC protocol incompatibility, and ASIL-B diagnostic coverage details essential for automotive position-sensing design validation.
Technical Context
The MLX90377GDC-ADB-300-SP implements Triaxis® Hall front-end sensing of Bx, By, and Bz magnetic components, coupled with on-chip DSP for real-time angle calculation and programmable piecewise-linear transfer characteristic (4/8/16/32 points). Its analog/PWM output path operates in Low Power Mode with 8–11 mA supply current and supports ratiometric scaling referenced to VDD.
This variant uses Standard/Legacy Mode (-3xx option code), excludes SENT/SPC protocols, and lacks dual-die redundancy-confirmed by SOIC-8 packaging and ADB-300 option code. It integrates internal analog regulator, reverse polarity protection, overvoltage clamp, and temperature sensor, enabling direct integration into harsh automotive environments without external conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Mode | Analog ratiometric or PWM only; SENT and SPC disabled per ADB-300 option code-no field reconfiguration possible. |
| Resolution | 12-bit effective resolution for angular or linear position output, enabling ≤0.1° or ≤0.025 mm precision in calibrated systems. |
| Operating Temp | -40°C to +160°C ambient range-supports under-hood placement in engine management and transmission control units. |
| Supply Current | 8–11 mA typical in Low Power Mode-reduces thermal load and enables use with low-capacity power rails. |
| Safety Rating | ISO 26262 ASIL-B compliant for analog output mode as Safety Element out of Context (SEooC); no ASIL-C support in this variant. |
| Magnetic Sensing | Triaxis® 3-axis Hall front-end measures Bx, By, Bz simultaneously-enables robust absolute position decoding independent of magnet orientation. |
| Package | SOIC-8 (DC code), RoHS-compliant, with pins VDD, Input, Test, N.C., OUT, N.C., VDEC, VSS-requires external decoupling at VDEC. |
Pinout & Package
MLX90377GDC-ADB-300-SP uses SOIC-8 package (DC code) with integrated analog regulator and reverse-polarity protection. VDEC requires 100 nF ceramic capacitor to ground for stable operation; unused pins (Test, N.C.) must be tied to VSS for EMC compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VDD | Power supply input | 4.5–5.5 V regulated or 6–18 V battery-supplied rail; includes overvoltage clamp up to 37 V transient tolerance. |
| 2: Input | Test/external measurement interface | Factory test access point; not intended for end-user signal routing-connect to VSS unless used for calibration verification. |
| 3: Test | Internal diagnostics port | Melexis production test node; must be grounded per datasheet for optimal EMC-no functional role in application circuit. |
| 4: N.C. | No connection | Unbonded die pad; electrically isolated-tie to VSS to minimize EMI susceptibility. |
| 5: OUT | Analog/PWM output driver | Push-pull capable; delivers ratiometric voltage (0.5–3.3%VDD low / 97–99%VDD high) or PWM duty cycle proportional to position. |
| 6: N.C. | No connection | Unbonded die pad; electrically isolated-tie to VSS to minimize EMI susceptibility. |
| 7: VDEC | Internal analog regulator decoupling | Requires 100 nF X7R ceramic capacitor to VSS; omission causes output instability and increased noise sensitivity. |
| 8: VSS | Ground reference | Primary return path for analog/digital domains; must be low-impedance and star-connected to avoid ground bounce in noisy environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Sensing | Simultaneous Bx/By/Bz measurement enables absolute position decoding with single magnet-eliminates need for multi-sensor arrays or complex mechanical couplings. |
| Programmable Transfer Curve | Supports 4-, 8-, 16-, or 32-point piecewise-linear calibration-allows precise linearization of non-ideal magnetic fields without host MCU intervention. |
| Low-Power Analog/PWM Mode | 8–11 mA supply current at 5 V-reduces thermal stress in sealed enclosures and extends battery life in low-duty-cycle applications. |
| ASIL-B Functional Safety | Compliant for analog output per ISO 26262 SEooC requirements-includes watchdog timers, memory ECC, and diagnostic coverage for critical failure modes. |
| Stray-Field Immunity | Standard/Legacy Mode (-3xx) provides baseline immunity-suitable for environments with moderate EMI but not high-current adjacent conductors. |
Applications

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-310-SP | Same SOIC-8 package and Triaxis® core, but configured for High Speed Mode (11–13.5 mA, faster update rate). | Required where <5 ms latency is mandatory-e.g., active suspension control loops-but increases power dissipation. | Select ADB-310 if system demands sub-5 ms response; ADB-300 remains optimal for cost-sensitive, thermally constrained pedal/throttle modules. |
| MLX90371GDC-ADB-000-SP | Legacy Triaxis® generation with fixed 8-point linearization, no SENT/SPC support, and narrower -40°C to +150°C range. | Limited to legacy designs requiring drop-in replacement without firmware updates-lacks ASIL-B certification and advanced diagnostics. | Choose MLX90371 only for backward compatibility; MLX90377GDC-ADB-300-SP offers superior accuracy, extended temp range, and functional safety documentation. |
Compared with MLX90377GDC-ADB-310-SP, the MLX90377GDC-ADB-300-SP trades 2–3 mA lower quiescent current and relaxed timing for reduced thermal load-ideal for space-constrained modules. Against MLX90371GDC-ADB-000-SP, it adds ASIL-B compliance, wider temperature margin, and programmable transfer curves-justifying migration in new designs targeting OEM Tier-1 qualification.

FAQ
What output protocols does the MLX90377GDC-ADB-300-SP support?
The MLX90377GDC-ADB-300-SP supports only analog ratiometric and PWM output modes, as defined by its ADB-300 option code. SENT and SPC protocols are permanently disabled in this variant and cannot be enabled via programming or external configuration-designers must select ADB-330 or ADB-380 variants for those interfaces.
Is the MLX90377GDC-ADB-300-SP pin-compatible with other MLX90377 package variants?
No-the MLX90377GDC-ADB-300-SP uses SOIC-8 packaging with 8 pins, while TSSOP-16 (GO), DMP-4 (VS), and SMP-3 (VE) variants have different pin counts, layouts, and electrical configurations. For example, DMP-4 has only 4 pins (VSS/VDD/OUT/VSS), making PCB redesign mandatory for substitution.
Does the MLX90377GDC-ADB-300-SP require external decoupling capacitors?
Yes-MLX90377GDC-ADB-300-SP requires a 100 nF X7R ceramic capacitor between VDEC (Pin 7) and VSS (Pin 8) to stabilize the internal analog regulator. Omitting this capacitor causes output noise, startup failures, and intermittent communication loss-per Section 3.1 and Figure 16.1 of the datasheet.
What functional safety level does the MLX90377GDC-ADB-300-SP achieve?
The MLX90377GDC-ADB-300-SP achieves ISO 26262 ASIL-B compliance for analog output mode as a Safety Element out of Context (SEooC). It does not meet ASIL-C requirements-those apply only to SENT/PWM/SPC variants like ADB-330 or ADB-310. Diagnostic coverage includes memory ECC, watchdog timers, and supply monitoring.
Can the MLX90377GDC-ADB-300-SP be reprogrammed to change its output mode after soldering?
No-output mode is固化 (hard-coded) by the ADB-300 option code at factory programming. The MLX90377GDC-ADB-300-SP cannot be reconfigured to SENT, SPC, or high-speed PWM modes in the field. Reprogramming is limited to calibration parameters (e.g., transfer curve points) using Melexis' PTM tool-not protocol selection.
