Product details
Overview
MLX90377GVE-ADB-110-TU from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC for absolute rotary position sensing in high-field stray-immune configurations. It delivers 12-bit resolution analog/PWM output with high-speed mode, operates from -40°C to 160°C, and uses SMP-3 package with 3-pin surface-mount footprint. It enables non-contact throttle or steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90377GVE-ADB-110-TU datasheet, pinout, applications, or equivalent options, key selection considerations include its Rotary Stray-Field Immune Mode (Low Field variant), SMP-3 mechanical form factor, analog/PWM high-speed output configuration, ASIL-B safety capability, and 12-bit measurement resolution.
Technical Context
The MLX90377GVE-ADB-110-TU integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling robust angular position decoding without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable filtering for dynamic response optimization.
This variant implements Rotary Stray-Field Immune Mode (Low Field variant, ADB-110), optimized for magnet configurations where external stray fields may interfere with angular measurement accuracy. It supports only analog and PWM output modes in high-speed configuration-SENT and SPC protocols are disabled per ordering code definition.

| Startup Time | ≤ 5 ms in high-speed analog/PWM mode, meeting fast-response requirements for real-time torque or pedal control loops |
Pinout & Package
SMP-3 is a PCB-less single-mold package with 3 solderable terminals and integrated decoupling capacitance. It provides compact, low-profile mounting for space-constrained rotary sensor assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Power Supply Input | Accepts 4.5–5.5 V regulated supply; internal regulator powers analog and digital blocks |
| 2 (OUT) | Programmable Output Terminal | Delivers ratiometric analog voltage (0.5–4.5 V) or PWM signal (10–90% duty cycle) depending on factory programming |
| 3 (VSS) | Ground Reference | Primary return path for supply and output current; must be low-impedance for EMC robustness |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field vector resolution for accurate angular position decoding |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVE-ADB-310-TU | Standard/Legacy Mode (not stray-field immune); same SMP-3 package and analog/PWM high-speed output | Lacks rotary stray-field immunity; requires additional magnetic shielding in noisy environments | Select when cost sensitivity outweighs stray-field rejection needs and system layout allows shielding |
| MLX90377GDC-ADB-110-RE | Same Rotary Stray-Field Immune Mode (Low Field) and output configuration, but in SOIC-8 package | SOIC-8 requires larger PCB area and external decoupling capacitors; less suited for ultra-compact modules | Choose for legacy board compatibility or when higher thermal mass improves long-term drift stability |
Compared with MLX90377GVE-ADB-110-TU, the ADB-310 variant trades stray-field immunity for broader magnetic field tolerance in benign environments, while the ADB-110 in SOIC-8 offers identical sensing performance with greater layout flexibility at the expense of size and integration density.

FAQ
What output protocols does the MLX90377GVE-ADB-110-TU support?
The MLX90377GVE-ADB-110-TU is factory-programmed for analog ratiometric and PWM output modes only, operating in high-speed configuration. SENT and SPC protocols are not enabled for this ADB-110 option code-output protocol is fixed at manufacture and cannot be reconfigured in the field.
Is the MLX90377GVE-ADB-110-TU pin-compatible with other MLX90377 package variants?
No-the MLX90377GVE-ADB-110-TU uses the 3-terminal SMP-3 package, which has different pin count, spacing, and terminal assignment than SOIC-8 (8-pin), TSSOP-16 (16-pin), or DMP-4 (4-pin) variants. Direct PCB replacement requires layout redesign and mechanical requalification.
What magnetic configuration is required for optimal performance of the MLX90377GVE-ADB-110-TU?
The MLX90377GVE-ADB-110-TU is configured for Rotary Stray-Field Immune Mode (Low Field variant), requiring a diametrically magnetized ring magnet positioned coaxially with the sensor's top surface. Magnet air gap and radial offset must stay within ±0.3 mm to maintain ±0.3° accuracy.
Does the MLX90377GVE-ADB-110-TU include built-in protection features?
Yes-the MLX90377GVE-ADB-110-TU integrates reverse polarity protection (−14 V), overvoltage tolerance (37 V), and broken-wire diagnostics for both VDD and VSS lines. These protections are active across the full −40°C to +160°C operating range without external components.
Can the MLX90377GVE-ADB-110-TU be used in ASIL-C systems?
No-the MLX90377GVE-ADB-110-TU is certified ISO 26262 ASIL-B capable for analog output mode only. ASIL-C capability applies exclusively to SENT, PWM, and SPC outputs in specific ADB-xxx codes (e.g., ADB-330, ADB-310), not to this ADB-110 configuration.
