Product details
Overview
MLX90377GVE-ADB-230-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC designed for high-reliability linear position sensing in harsh environments. It delivers 12-bit SENT output with 3 μs tick time, operates from -40°C to 160°C, features stray-field immunity for linear motion configurations, and is qualified per ISO 26262 ASIL-C for SENT mode - deployed in automotive pedal and throttle position systems.
For engineers reviewing the MLX90377GVE-ADB-230-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SMP-3), confirmed SENT timing (3 μs), functional safety classification (ASIL-C), magnetic accuracy specs (±0.5° typical linearity error), and real-world use-case validation for linear non-contact sensing under EMI stress.
Technical Context
The MLX90377GVE-ADB-230-RE implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components on a single die, enabling absolute linear position decoding without mechanical contact. Its DSP-based signal conditioning supports programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable SENT frame structure with diagnostic nibbles.
This variant uses Linear Stray-Field Immune Mode (-2xx option code), optimized for robustness against external magnetic interference in linear stroke applications. It integrates analog regulation, reverse-polarity protection, overvoltage protection, and a 12-bit SENT output stage compliant with SAE J2716 APR2016, with startup time < 10 ms and latency < 1.5 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT (SAE J2716 APR2016), 3 μs tick time - enables high-speed, error-coded digital position reporting with CRC and status nibbles. |
| Operating Temp | -40°C to +160°C - supports under-hood automotive deployment without derating or external thermal management. |
| Supply Voltage | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - dual-mode supply handling for direct vehicle battery interfacing in PWM mode (not active here). |
| Accuracy | ±0.5° typical INL (Linear Stray-Field Immune Mode) - ensures sub-degree resolution for precision linear displacement feedback. |
| Functional Safety | ISO 26262 ASIL-C capable (SENT mode), Safety Element out of Context - meets requirements for critical vehicle control loops. |
| Package | SMP-3 (PCB-less single mold) - ultra-compact 3-pin surface-mount package with integrated decoupling, optimized for space-constrained linear sensor assemblies. |
| Stray-Field Immunity | Linear Stray-Field Immune Mode (-2xx) - rejects orthogonal magnetic interference up to ±1 T, validated for pedal/ride-height sensors near motors or solenoids. |
Pinout & Package
SMP-3 is a PCB-less single-mold package with three solderable terminals and two test pads (INPUT and TEST), designed for direct magnet coupling in compact linear position modules. It integrates internal decoupling capacitance and requires no external bypass capacitors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Supply input | Accepts 4.5–18 V; includes reverse-polarity and overvoltage protection; powers internal analog/digital regulators. |
| 2 (OUT) | Digital SENT output | Push-pull SENT driver with 3 μs tick timing; outputs 12-bit position + diagnostics; compatible with standard SENT receivers. |
| 3 (VSS) | Ground reference | Primary return path; used for broken-wire detection (BVSSPU/BVSSPD diagnostics); must be low-impedance for EMC. |
| a (INPUT) | Test input | Factory test access point; not intended for end-user connection; recommended to tie to VSS for EMC stability. |
| b (TEST) | Test control | Internal test mode enable; not user-accessible in normal operation; recommended to tie to VSS for EMC stability. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true absolute linear position decoding without angular ambiguity or homing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute linear position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GDC-ADB-230-RE | SOIC-8 package (8-pin), larger footprint, requires external decoupling capacitors, same SENT timing and stray-field immunity. | Preferred where board space permits and legacy PCB layout reuse is required; less suitable for ultra-compact linear actuators. | Select when leveraging existing SOIC-8 footprints or requiring higher thermal mass for extended high-temp soak testing. |
| MLX90377GO-ADB-230-RE | TSSOP-16 dual-die package with inter-die isolation (>4 MΩ), redundant architecture, identical SENT output and linear mode. | Required for ASIL-D system decomposition or where hardware redundancy is mandated; adds cost and board area. | Choose only when functional safety architecture demands dual independent dies - not needed for ASIL-C standalone implementation. |
Compared with MLX90377GDC-ADB-230-RE and MLX90377GO-ADB-230-RE, the MLX90377GVE-ADB-230-RE offers the smallest PCB footprint and lowest BOM count via integrated decoupling, while retaining identical SENT performance, stray-field immunity, and ASIL-C qualification - making it optimal for space- and weight-critical linear sensor modules.

FAQ
What output protocol does the MLX90377GVE-ADB-230-RE support?
The MLX90377GVE-ADB-230-RE supports SENT output only, configured per SAE J2716 APR2016 with 3 μs tick time. It does not support analog, PWM, or SPC modes - the ADB-230 option code explicitly selects SENT in Linear Stray-Field Immune Mode. This fixed configuration is factory-programmed and cannot be changed in the field.
Is the MLX90377GVE-ADB-230-RE pin-compatible with other MLX90377 variants?
No - the MLX90377GVE-ADB-230-RE uses the SMP-3 package with 3 main terminals (VDD, OUT, VSS) and two test pads, differing physically and electrically from SOIC-8 (8 pins), TSSOP-16 (16 pins), or DMP-4 (4 pins). Pin compatibility is not maintained across package types; each requires unique PCB layout and routing.
Does the MLX90377GVE-ADB-230-RE require external decoupling capacitors?
No. The SMP-3 package integrates internal decoupling capacitance optimized for the MLX90377GVE-ADB-230-RE's power domains. External capacitors are unnecessary and not recommended - adding them may disrupt timing margins and SENT signal integrity due to parasitic inductance.
What is the functional safety qualification status of the MLX90377GVE-ADB-230-RE?
The MLX90377GVE-ADB-230-RE is ISO 26262 ASIL-C capable for SENT output mode and ASIL-B capable for analog mode (though analog is disabled in this variant). It is certified as a Safety Element out of Context (SEooC), with documented fault handling time intervals < 10 ms and integrated diagnostics including CRC, watchdogs, and memory ECC.
How does Linear Stray-Field Immunity work in the MLX90377GVE-ADB-230-RE?
The MLX90377GVE-ADB-230-RE uses a dedicated magnetic front-end calibration and DSP filter set tuned for linear motion topologies, rejecting orthogonal magnetic interference up to ±1 T. This is achieved via hardware-level IMC design and firmware algorithms - not software configuration - and is validated per section 8.2 of the datasheet for -2xx option codes.
