Product details
Overview
MLX90377GVE-ADB-310-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SMP-3 package, delivering 12-bit resolution analog and PWM outputs with high-speed mode timing (≤100 µs latency), ±0.5° angular accuracy over -40°C to +160°C, and stray-field immunity for rotary/linear sensing in automotive throttle and pedal applications.
For engineers reviewing the MLX90377GVE-ADB-310-RE datasheet, pinout, applications, or equivalent options, this page delivers verified pin definitions, output protocol constraints, functional safety classification (ASIL-B for analog mode), magnetic field tolerance (±1 T), and real-world use cases including non-contacting potentiometer replacement and ride height sensing.
Technical Context
The MLX90377GVE-ADB-310-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, a 12-bit ADC, DSP-based signal processing engine, and programmable analog/PWM output stage. Its SMP-3 package embeds decoupling capacitors and supports only high-speed analog/PWM operation per ADB-310 configuration.
This variant operates in Standard/Legacy Mode with High Speed Mode enabled (ADB-310), delivering ≤100 µs latency and 12-bit resolution. It lacks SENT/SPC capability and is not dual-die-functional safety is rated ASIL-B for analog output only, with no ASIL-C claim for this specific option.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric and PWM only; SENT/SPC disabled per ADB-310 configuration |
| Resolution | 12-bit (4096 steps) for both analog voltage and PWM duty cycle encoding |
| Latency | ≤100 µs typical in High Speed Mode-critical for closed-loop throttle control response |
| Angular Accuracy | ±0.5° over full temperature range (-40°C to +160°C) in Standard/Legacy Mode |
| Magnetic Range | ±1 T maximum flux density tolerance-enables robust operation near motors or solenoids |
| Supply Voltage | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery); startup threshold at 4.1 V nominal |
| Operating Temp | -40°C to +160°C ambient-qualified for under-hood automotive placement |
Pinout & Package
SMP-3 is a PCB-less single-mold package with three solderable terminals (VDD, OUT, VSS) and two test pads (INPUT, TEST). It integrates decoupling capacitance and targets space-constrained, high-vibration environments such as throttle bodies and suspension modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Power supply input | Accepts 4.5–18 V; internal regulator powers analog/digital blocks; requires external 100 nF ceramic capacitor if not using built-in capacitance |
| 2 (OUT) | Programmable output terminal | Delivers ratiometric analog voltage (0.5–4.5 V) or PWM (10–90% duty cycle); push-pull capable; supports 10 kΩ load minimum |
| 3 (VSS) | Ground reference | Primary return path for supply and signal; must be low-impedance connection to avoid offset drift in analog output |
| a (INPUT) | Factory test interface | Not user-accessible in final application; used during wafer probe and calibration; leave floating or grounded per design |
| b (TEST) | Factory diagnostic pin | Internal test node; no user function; recommended to tie to VSS for EMC stability |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous measurement of Bx, By, Bz enables absolute angle/position decoding without mechanical gears or brushes |
| High-Speed Analog/PWM | ≤100 µs latency and 12-bit resolution support real-time engine control loop timing requirements |
| Stray-Field Immunity | Configured for Standard/Legacy Mode (ADB-310), providing inherent rejection of external magnetic interference up to ±1 T |
| Integrated Decoupling | SMP-3 package includes embedded capacitors-eliminates need for external VDD/VSS bypass components |
| ASIL-B Functional Safety | Validated for analog output mode per ISO 26262; includes diagnostics for broken-wire detection on VDD/VSS |

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-RE | SOIC-8 package with 8 pins; requires external decoupling capacitors; same ADB-310 output configuration and timing | Used where PCB mounting and manual rework access are required; less suitable for high-vibration direct-mount applications | Select when board-level assembly and test accessibility outweigh space/vibration constraints |
| MLX90377GO-ADB-310-RE | TSSOP-16 dual-die package; provides hardware redundancy; ASIL-C rated for PWM output; higher pin count and isolation between dies | Required for dual-channel safety-critical systems (e.g., steer-by-wire) where fault containment is mandatory | Choose only when ISO 26262 ASIL-C compliance and die-level redundancy are system requirements |
Compared with MLX90377GVE-ADB-310-RE, the SOIC-8 variant offers easier prototyping but adds layout area and external BOM items, while the TSSOP-16 version delivers safety-certified redundancy at the cost of size and complexity-neither is pin-compatible due to differing terminal counts and physical form factors.

FAQ
What output protocols does MLX90377GVE-ADB-310-RE support?
The MLX90377GVE-ADB-310-RE supports only analog ratiometric voltage and PWM outputs in High Speed Mode. SENT and SPC protocols are disabled by its ADB-310 configuration code-this is factory-programmed and not reprogrammable in the field. The device delivers 12-bit resolution on both outputs with ≤100 µs latency.
Is MLX90377GVE-ADB-310-RE pin-compatible with other MLX90377 variants?
No, MLX90377GVE-ADB-310-RE is not pin-compatible with SOIC-8 or TSSOP-16 variants. Its SMP-3 package has only three solderable terminals (VDD, OUT, VSS), whereas SOIC-8 uses 8 pins and TSSOP-16 uses 16. Pin definitions, spacing, and thermal pad presence differ fundamentally-PCB redesign is required for substitution.
What functional safety level is certified for MLX90377GVE-ADB-310-RE?
MLX90377GVE-ADB-310-RE is ISO 26262 ASIL-B capable for analog output mode only. It does not achieve ASIL-C rating because ASIL-C requires dual-die redundancy (TSSOP-16 package) and SENT/SPC protocol support-both absent in this SMP-3, analog/PWM-only variant.
Does MLX90377GVE-ADB-310-RE require external decoupling capacitors?
No. The SMP-3 package of MLX90377GVE-ADB-310-RE integrates decoupling capacitance internally. Unlike SOIC-8 or TSSOP-16 versions, it does not require external VDD/VSS bypass capacitors-this reduces BOM count and improves reliability in high-vibration mounting scenarios like throttle bodies.
Can MLX90377GVE-ADB-310-RE be used for linear position sensing?
Yes. MLX90377GVE-ADB-310-RE supports both absolute rotary and linear position sensing via Triaxis® 3D Hall technology. When paired with a linear magnet array or moving ferrous target, it delivers 12-bit linear displacement output with ±0.5° equivalent angular error translated to position accuracy-validated in float-level and ride height applications.
