Product details
Overview
MLX90377GVE-ADB-210-RX from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute linear position sensing in stray-field-immune mode, delivering 12-bit analog and PWM outputs with ±0.5° typical angular accuracy, 4.5–5.5 V supply operation, and -40°C to +160°C operating range - deployed in automotive pedal and throttle position sensing.
For engineers reviewing the MLX90377GVE-ADB-210-RX datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (SMP-3), confirmed output protocol (Analog/PWM, High Speed Mode), functional safety classification (ASIL-B for analog), and real-world use-case constraints including stray-field immunity and PCB-less mounting requirements.
Technical Context
The MLX90377GVE-ADB-210-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute position decoding from linear magnet motion without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable filtering for noise suppression in harsh EMI environments.
This variant operates exclusively in Linear Stray-Field Immune Mode (-2xx option code) with Analog/PWM output in High Speed Mode (-210), requiring no reprogramming for protocol change. It uses the SMP-3 PCB-less single-mold package with integrated decoupling, and achieves ASIL-B compliance per ISO 26262 for analog output - distinct from SENT/SPC variants rated ASIL-C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric (12-bit) and PWM (12-bit), fixed at High Speed Mode - not field-reprogrammable. |
| Accuracy | ±0.5° typical total error over full temperature range (-40°C to +160°C) in Linear Stray-Field Immune Mode. |
| Supply Voltage | 4.5 V to 5.5 V (regulated); supports 6–18 V battery input only in PWM mode - critical for automotive integration. |
| Functional Safety | ISO 26262 ASIL-B compliant for analog output; ASIL-C not applicable - designates safety-critical use with diagnostic coverage limited to analog path. |
| Stray-Field Immunity | Validated for Linear Stray-Field Immune Mode (-2xx), rejecting external magnetic interference up to ±1 T without calibration loss. |
| Startup Time | ≤ 3 ms in High Speed Mode (Tstup3), enabling fast system wake-up after ignition - measured from VDD ≥ 4.1 V to first valid angle output. |
| Operating Temp | -40°C to +160°C junction temperature - qualified for under-hood automotive placement without derating. |
Pinout & Package
SMP-3 is a PCB-less single-mold package with three solderable terminals (VDD, OUT, VSS) and two test pads (INPUT, TEST), optimized for direct magnet-side mounting and high-volume automated assembly. No external decoupling capacitors required due to integrated regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Power supply input | Accepts 4.5–5.5 V regulated supply; internal regulator enables stable core operation despite rail noise. |
| 2 (OUT) | Signal output | Push-pull capable; delivers either ratiometric analog voltage (0.5–4.5 V) or PWM (10–90% duty cycle) based on factory configuration. |
| 3 (VSS) | Ground reference | Low-impedance return path; must be connected directly to system ground plane to maintain stray-field immunity. |
| a (INPUT) | Factory test interface | Not user-accessible in final application; used during wafer-level testing and calibration - left floating or grounded per layout guidelines. |
| b (TEST) | Factory test interface | Reserved for Melexis production diagnostics; no functional role in end equipment - must be grounded for EMC compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall sensing | Enables absolute linear position detection using only one magnet and no mechanical linkage - eliminates wear and hysteresis. |
| Linear Stray-Field Immune Mode | Guarantees ±0.5° accuracy under external magnetic fields up to ±1 T - validated per IEC 61000-4-8, critical for EV powertrain proximity. |
| Programmable transfer characteristic | Supports up to 32-point piecewise-linear calibration - allows precise matching to non-uniform mechanical travel profiles (e.g., brake pedal stroke). |
| Integrated analog/PWM dual output | Provides redundant signal paths without external circuitry - analog for ECU ADC sampling, PWM for direct microcontroller timer capture. |
| SMP-3 package with built-in decoupling | Reduces BOM count by eliminating external 100 nF ceramic capacitor - simplifies layout and improves reliability in vibration-prone environments. |
Applications
| Pedal Position Sensing | Throttle Position Sensing |
|---|---|
|
Use Scenario: Real-time monitoring of accelerator or brake pedal displacement in ICE and BEV powertrains. IC Role / Device Role / Timing Role: Absolute linear position transducer converting magnet motion into ratiometric analog voltage and synchronized PWM pulses.

Use Value: Delivers stable 12-bit linearity without potentiometer wear or wiper contact failure - extends service life beyond 10 years. |
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-RX | Standard/Legacy Mode (not stray-field immune); same SMP-3 package, analog/PWM high-speed output. | Lacks validated immunity to ±1 T external fields - unsuitable for proximity to high-current busbars or motors. | Select only for cost-sensitive non-safety-critical linear sensing where magnetic environment is controlled and calibrated. |
| MLX90371GSE-ADB-010-SP | Legacy Triaxis® device in SOIC-8; 10-bit analog/PWM output; no ASIL-B certification; -40°C to +150°C rating. | Lower resolution, no functional safety qualification, and reduced temperature margin - not drop-in compatible. | Use only for legacy redesigns where footprint compatibility with SOIC-8 is mandatory and safety requirements are absent. |
Compared with MLX90377GVE-ADB-210-RX, the ADB-310-RX sacrifices stray-field immunity for lower cost in benign environments, while the MLX90371GSE-ADB-010-SP trades resolution, safety compliance, and thermal range for SOIC-8 footprint reuse - neither matches the full specification set of the ADB-210-RX for new ASIL-B automotive designs.

FAQ
What output protocols does the MLX90377GVE-ADB-210-RX support?
The MLX90377GVE-ADB-210-RX is factory-configured for Analog ratiometric (12-bit) and PWM (12-bit) output in High Speed Mode only. SENT and SPC protocols are not enabled - they require different option codes (e.g., -230 or -280) and cannot be reprogrammed post-manufacture.
Is the MLX90377GVE-ADB-210-RX pin-compatible with other MLX90377 variants in SMP-3 package?
Yes, all MLX90377 variants in SMP-3 package (VE suffix) share identical pinout: VDD (Pin 1), OUT (Pin 2), VSS (Pin 3), plus INPUT (a) and TEST (b) test pads. However, electrical behavior differs - only ADB-210-RX provides Linear Stray-Field Immune Mode with ASIL-B compliance.
Does the MLX90377GVE-ADB-210-RX require external decoupling capacitors?
No. The MLX90377GVE-ADB-210-RX in SMP-3 package integrates internal decoupling capacitance, eliminating the need for external 100 nF ceramic capacitors. This reduces PCB area and improves reliability in high-vibration applications like suspension sensors.
What is the functional safety status of the MLX90377GVE-ADB-210-RX?
The MLX90377GVE-ADB-210-RX is ISO 26262 ASIL-B compliant for its analog output path and ASIL-C capable for SENT/SPC modes - but since ADB-210-RX is configured for analog/PWM only, only ASIL-B applies. Full safety manual and FMEDA reports are available from Melexis upon NDA.
Can the MLX90377GVE-ADB-210-RX be used for rotary position sensing?
No. The MLX90377GVE-ADB-210-RX is configured for Linear Stray-Field Immune Mode (-2xx), which is validated only for linear magnet motion (e.g., pedal stroke). Rotary applications require -1xx (Rotary Low Field) or -5xx (Rotary High Field) variants - using ADB-210-RX for rotary sensing voids accuracy and immunity guarantees.
