Product details
Overview
MLX90377GVE-ADB-110-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SMP-3 package, operating from -40°C to 160°C, delivering 12-bit analog/PWM output with high-speed mode, and supporting rotary stray-field immune (low-field variant) magnetic configurations. It decodes absolute angular position via Bx/By/Bz field components for non-contacting throttle or steering wheel sensing.
For engineers reviewing the MLX90377GVE-ADB-110-RE datasheet, pinout, applications, or equivalent options, key selection factors include its SMP-3 footprint, 12-bit analog/PWM output timing, rotary stray-field immunity, ISO26262 ASIL-C capability in PWM mode, and programmable linear transfer characteristic with up to 32-piecewise-linear points.
Technical Context
The MLX90377GVE-ADB-110-RE integrates a Triaxis® Hall front end, 12-bit ADC, DSP for real-time signal processing, and analog/PWM output stage - all on a single die. Its rotary stray-field immune (low-field) configuration enables robust operation under external magnetic interference while maintaining ±0.5° typical angular accuracy over full temperature range.
This variant uses the SMP-3 PCB-less single-mold package with 3 terminals (VDD, OUT, VSS), supports 4.5–5.5 V regulated supply or 6–18 V battery input, and delivers startup time ≤3 ms in high-speed analog/PWM mode with latency <1.5 ms and step response <2.5 ms (100% settling).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments without derating. |
| Output Resolution | 12-bit - provides 0.0879° angular resolution over 0–360° range for precise closed-loop control. |
| Supply Voltage | 4.5–5.5 V (regulated) or 6–18 V (battery) - dual-mode support simplifies integration into 12 V vehicle systems. |
| Startup Time | ≤3 ms in high-speed mode - enables rapid system readiness after ignition-on for safety-critical applications. |
| Latency | <1.5 ms - ensures minimal phase lag between magnet motion and output signal for real-time feedback loops. |
| Magnetic Immunity | Rotary Stray-Field Immune (Low Field Variant) - rejects interference from adjacent motors or solenoids in compact assemblies. |
| Functional Safety | ISO26262 ASIL-C capable in PWM mode - certified as Safety Element out of Context for automotive safety architectures. |
Pinout & Package
SMP-3 is a PCB-less single-mold package with three solderable terminals and two test pads (INPUT, TEST), optimized for direct magnet coupling and space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Supply Input | Accepts 4.5–18 V; internal regulator powers analog/digital blocks; reverse polarity protected to -14 V. |
| 2 (OUT) | Analog/PWM Output | Push-pull or open-drain configurable; 12-bit ratiometric analog (0.5–99% VDD) or PWM (10–90% duty cycle). |
| 3 (VSS) | Ground Reference | Common return for supply and output; used in broken-wire diagnostics (BVSSPD/BVSSPU detection). |
| a (INPUT) | Test Interface | Factory calibration and diagnostic access; not intended for end-user circuit connection. |
| b (TEST) | Test Interface | Internal debug/test node; must be tied to VSS per EMC recommendations if unused. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Measures Bx, By, Bz simultaneously to resolve absolute angle without mechanical stops or multi-die redundancy. |
| Programmable Transfer Curve | Supports 4-, 8-, 16-, or 32-point piecewise-linear mapping - enables custom linearization for non-uniform magnet geometries. |
| Stray-Field Immunity | Rotary low-field variant (-1xx option code) suppresses interference from nearby 50–200 mT fields, critical for EPS and transmission sensors. |
| High-Speed Analog/PWM | Configured via ADB-110 option: enables ≤3 ms startup and sub-1.5 ms latency for responsive throttle or pedal control loops. |
| Integrated Diagnostics | Includes broken-wire detection (VDD/VSS), watchdog timers, and SENT/SPC CRC - reduces need for external safety monitoring ICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVE-ADB-310-RE | Standard/Legacy Mode (not stray-field immune); same SMP-3 package and 12-bit analog/PWM output. | Lacks rotary stray-field immunity; suitable only in magnetically quiet environments like cabin controls. | Select when cost optimization is prioritized over field immunity and ambient magnetic noise is negligible. |
| MLX90377GDC-ADB-110-RE | Same rotary stray-field immune (low-field) configuration and high-speed analog/PWM mode, but in SOIC-8 package. | SOIC-8 requires PCB mounting and larger footprint; lacks SMP-3's direct magnet coupling advantage. | Choose when board-level integration is preferred over embedded magnet proximity, and thermal cycling reliability is less critical. |
Compared with MLX90377GVE-ADB-110-RE, the ADB-310 variant trades stray-field immunity for lower cost in benign environments, while the ADB-110 in SOIC-8 offers identical sensing performance but sacrifices the mechanical and thermal advantages of the SMP-3 mold-on-chip construction.

FAQ
What output protocols does the MLX90377GVE-ADB-110-RE support?
The MLX90377GVE-ADB-110-RE supports analog ratiometric and PWM output modes only - configured via its ADB-110 option code. It does not support SENT or SPC protocols. The analog output spans 0.5–99% of VDD, and PWM delivers 10–90% duty cycle with 12-bit resolution, both operating in high-speed mode with ≤3 ms startup.
Is the MLX90377GVE-ADB-110-RE pin-compatible with other MLX90377 variants in SMP-3 package?
Yes, all MLX90377 variants in SMP-3 package - including MLX90377GVE-ADB-110-RE, ADB-210-RE, and ADB-310-RE - share identical 3-terminal pinout (VDD, OUT, VSS) and mechanical footprint. Functional differences arise solely from factory-programmed firmware settings, not hardware layout.
Does the MLX90377GVE-ADB-110-RE require external decoupling capacitors?
No. The MLX90377GVE-ADB-110-RE in SMP-3 package integrates internal decoupling capacitance, eliminating the need for external VDEC capacitors. This simplifies PCB design and improves reliability in vibration-prone automotive locations where capacitor solder joint fatigue is a concern.
How is stray-field immunity implemented in the MLX90377GVE-ADB-110-RE?
The MLX90377GVE-ADB-110-RE achieves rotary stray-field immunity through on-chip differential Triaxis® sensing and proprietary signal processing that cancels common-mode magnetic interference up to ±200 mT. This is factory-configured for low-field rotary applications and cannot be reprogrammed by the end user.
What functional safety certification applies to the MLX90377GVE-ADB-110-RE?
The MLX90377GVE-ADB-110-RE is ISO26262 ASIL-C capable in PWM output mode and ASIL-B capable in analog mode, certified as a Safety Element out of Context (SEooC). Its diagnostic coverage includes broken-wire detection, watchdog timers, and internal voltage monitoring - all documented in Melexis' official safety manual.
