Product details
Overview
MLX90377GVE-ADB-230-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC for absolute linear position sensing in stray-field-immune mode, delivering 12-bit SENT output with 3 μs tick time, operating from -40°C to 160°C, and housed in SMP-3 package with integrated decoupling.
For engineers reviewing the MLX90377GVE-ADB-230-SP datasheet, pinout, applications, or equivalent options, this page delivers verified functional specifications, SMP-3 terminal mapping, ISO26262 ASIL-C safety capability for SENT mode, and validated alternatives for automotive pedal and throttle position sensing.
Technical Context
The MLX90377GVE-ADB-230-SP implements Triaxis® sensing of Bx, By, and Bz magnetic field components to resolve absolute linear displacement without contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and real-time stray-field immunity via dedicated magnetic configuration firmware.
This variant uses Linear Stray-Field Immune Mode (-2xx option code), fixed 3 μs SENT tick timing per SAE J2716 APR2016, and operates with supply voltage from 4.5 V to 5.5 V (regulated) or 6–18 V (battery). It achieves ASIL-C compliance for SENT output as a Safety Element out of Context per ISO26262.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT v4.0 (SAE J2716 APR2016), 3 μs tick time - enables high-resolution, error-coded digital transmission compatible with automotive ECUs. |
| Resolution | 12-bit position data - delivers 4096 distinct position steps over full range, supporting sub-degree or sub-millimeter accuracy. |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments including throttle bodies and brake pedals. |
| Supply Voltage | 4.5–5.5 V (regulated) or 6–18 V (battery) - supports dual power domains with reverse polarity and overvoltage protection. |
| Magnetic Mode | Linear Stray-Field Immune (-2xx) - rejects interference from nearby motors or solenoids while maintaining linearity in linear motion applications. |
| Package | SMP-3 (PCB-less single mold) - ultra-compact 3-pin surface-mount package with built-in decoupling capacitors, reducing external BOM count. |
| Safety Rating | ISO26262 ASIL-C for SENT output - certified as Safety Element out of Context, enabling integration into ASIL-C system architectures without additional hardware redundancy. |
Pinout & Package
SMP-3 is a PCB-less single-mold package with three solderable terminals and two test pads (INPUT and TEST), optimized for space-constrained linear position sensing modules. Built-in decoupling capacitors eliminate need for external VDD/VSS bypassing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Primary supply input | Accepts 4.5–18 V; internal regulator powers analog/digital blocks; reverse-polarity protected up to -14 V. |
| 2 (OUT) | Digital SENT output driver | Push-pull SENT signal with 27–130 Ω Ron; compliant with SAE J2716 timing; supports diagnostic nibbles and CRC. |
| 3 (VSS) | Ground reference | Common return for supply and output; used in broken-wire detection (BVSSPU/BVSSPD diagnostics). |
| a (INPUT) | Factory test / external measurement | Not user-accessible in normal operation; tied internally during calibration; no external connection required. |
| b (TEST) | Factory test interface | Used only during production programming; left floating or grounded per Melexis recommendations; not for end-user use. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous measurement of Bx, By, Bz enables robust absolute position decoding from magnet motion-no mechanical wipers or potentiometers required. |
| Programmable Transfer Curve | Up to 32-point piecewise-linear (PWL) calibration stored in NVRAM-allows precise linearization for custom magnetic circuits without host MCU intervention. |
| Stray-Field Immunity | Hardware-optimized linear mode (-2xx) rejects >95% of orthogonal interfering fields-critical for placement near motors, solenoids, or high-current traces. |
| SENT Diagnostics | Embedded status & communication nibble (SCN) reports sensor health, temperature, and fault codes-reduces ECU software overhead for safety-critical monitoring. |
| Integrated Decoupling | SMP-3 package embeds ceramic capacitors between VDD and VSS-eliminates external 100 nF bypass, saving PCB area and improving EMC robustness. |

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-210-SP | Analog/PWM output, same Linear Stray-Field Immune mode, identical SMP-3 package and temperature range. | Requires external ADC or PWM-timing circuitry; lacks SENT diagnostics and ECU-native protocol compatibility. | Select when legacy analog interface or cost-sensitive PWM readout is preferred over digital bus integration. |
| MLX90377GDC-ADB-230-RE | Same SENT output, Linear Stray-Field Immune mode, and ASIL-C capability-but in SOIC-8 package with separate decoupling requirements. | Larger footprint and higher assembly cost; requires external 100 nF VDD-VSS capacitor; less suitable for ultra-compact modules. | Choose when board-level reworkability, standard SOIC handling, or existing SOIC-8 layout reuse is prioritized over miniaturization. |
Compared with MLX90377GVE-ADB-210-SP, the MLX90377GVE-ADB-230-SP provides native ECU-ready SENT communication and embedded diagnostics; compared with MLX90377GDC-ADB-230-RE, it reduces component count and PCB area via SMP-3's integrated decoupling-making it optimal for space-constrained, high-reliability linear position sensing.

The MLX90377GVE-ADB-230-SP supports SENT v4.0 (SAE J2716 APR2016) with fixed 3 μs tick time. It does not support analog, PWM, or SPC modes-this variant is factory-configured exclusively for SENT output in Linear Stray-Field Immune mode. The protocol cannot be changed post-manufacture.
Is the MLX90377GVE-ADB-230-SP qualified for automotive safety applications?
Yes, the MLX90377GVE-ADB-230-SP is ISO26262 ASIL-C capable for its SENT output mode as a Safety Element out of Context. This certification covers fault detection, diagnostic coverage, and safe state behavior-enabling direct integration into ASIL-C system architectures without requiring redundant sensors.
What package type is used in the MLX90377GVE-ADB-230-SP?
The MLX90377GVE-ADB-230-SP uses the SMP-3 package: a PCB-less single-mold construction with three solderable terminals (VDD, OUT, VSS) and two test pads (INPUT, TEST). It integrates decoupling capacitors, eliminating external bypass components and reducing footprint to under 3.5 mm².
Can the MLX90377GVE-ADB-230-SP be reprogrammed for different transfer characteristics?
Yes, the MLX90377GVE-ADB-230-SP supports end-user programming of its transfer characteristic via Melexis' PTC interface-allowing up to 32-point piecewise-linear calibration to be written into NVRAM. This enables field adaptation to custom magnetic circuits without changing hardware.
Does the MLX90377GVE-ADB-230-SP require external decoupling capacitors?
No, the MLX90377GVE-ADB-230-SP in SMP-3 package includes embedded ceramic decoupling capacitors between VDD and VSS. No external 100 nF capacitor is needed-unlike SOIC-8 or TSSOP-16 variants-which simplifies layout and improves high-frequency noise immunity.
