Product details
Overview
MLX90377GVE-ADB-230-TU from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SMP-3 package, operating from -40°C to 160°C, delivering SENT output with 3 μs tick time and ASIL-C functional safety compliance for automotive pedal and throttle sensing.
For engineers reviewing the MLX90377GVE-ADB-230-TU datasheet, pinout, applications, or equivalent options, this page provides verified pin definitions, linear stray-field immune magnetic performance, SENT protocol timing, ISO 26262 ASIL-C capability, and direct alternative part comparisons for automotive position-sensing designs.
Technical Context
The MLX90377GVE-ADB-230-TU implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components to compute absolute angular or linear position without contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and real-time stray-field immunity for linear motion configurations.
This variant uses the SMP-3 PCB-less single-mold package with 3-pin terminal layout (VDD, OUT, VSS), configured exclusively for SENT output mode (3 μs tick time), and operates under Linear Stray-Field Immune Mode (-2xx option code) with 12-bit resolution and SAE J2716 APR2016 compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT (SAE J2716 APR2016), 3 μs tick time - enables secure, error-coded serial transmission with diagnostic nibbles for ECU integration. |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive applications including throttle and brake pedal sensors. |
| Magnetic Mode | Linear Stray-Field Immune (-2xx) - rejects interference from nearby magnets or currents, critical for compact chassis-mounted linear position sensing. |
| Resolution | 12-bit (4096 steps) - supports high-fidelity position feedback for closed-loop control in ASIL-C systems. |
| Functional Safety | ISO 26262 ASIL-C capable (SENT mode) - certified as Safety Element out of Context (SEooC) with documented fault handling time intervals. |
| Supply Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - dual-mode operation compatible with both microcontroller-supplied and vehicle-battery power rails. |
| Startup Time | Tstup ≤ 10 ms (SENT mode) - ensures rapid system readiness after ignition, meeting automotive cold-start timing requirements. |
Pinout & Package
SMP-3 is a PCB-less single-mold package with three solderable terminals and two test pads (INPUT, TEST). It integrates decoupling capacitance internally 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 up to -14 V / +28 V for robust automotive deployment. |
| 2 (OUT) | SENT output driver | Push-pull SENT signal with 12-bit data frame, CRC, status nibble, and configurable diagnostics - directly interfaces to standard SENT receivers. |
| 3 (VSS) | Ground reference | Common return path for supply and output; supports broken-wire detection (BVSSPU/BVSSPD) for fail-safe diagnostics. |
| a (INPUT) | Test input | Factory calibration and end-of-line test interface; not intended for user circuit connection. |
| b (TEST) | Test control | Internal debug/test access point; must be left unconnected or grounded per EMC recommendations. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true absolute position decoding from a single moving magnet - eliminates need for multi-die or external interpolation. |
| Linear Stray-Field Immunity | Configured via factory programming (-2xx option code) to reject orthogonal magnetic interference - validated for use near motors, solenoids, or adjacent sensors in tight packaging. |
| SENT Output with Diagnostics | Full SAE J2716 APR2016 compliance including status & communication nibble (SCN), CRC, and programmable error reporting - satisfies ASIL-C diagnostic coverage requirements. |
| Integrated Decoupling | On-package capacitance eliminates requirement for external VDD/VDEC capacitors - reduces PCB area and BOM count in space-constrained SMP-3 implementations. |
| ASIL-C SEooC Certification | Delivered with full safety manual, fault handling time interval (FHTI) documentation, and safety mechanism traceability - accelerates ISO 26262 integration into Tier-1 ECUs. |

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-230-RE | SOIC-8 package (8-pin), requires external decoupling capacitors, same SENT mode and Linear Stray-Field Immune configuration. | Used where PCB space allows traditional through-hole or surface-mount IC layout; lacks SMP-3's integrated capacitance and ultra-compact footprint. | Select when legacy board design or thermal management favors SOIC-8; verify VDEC capacitor placement per datasheet section 16.1. |
| MLX90377GO-ADB-230-RE | TSSOP-16 dual-die package with die-to-die isolation (>4 MΩ), identical SENT output but redundant architecture. | Required for ASIL-D systems needing hardware redundancy; supports cross-die comparison diagnostics not available in single-die SMP-3. | Choose only when dual-die fault tolerance is mandated; note higher current draw (15 mA vs. 13.5 mA) and larger PCB footprint. |
Compared with MLX90377GDC-ADB-230-RE and MLX90377GO-ADB-230-RE, the MLX90377GVE-ADB-230-TU delivers identical SENT functionality and stray-field immunity in the smallest possible form factor with zero external passive components - making it optimal for space- and weight-critical linear position sensing where single-point failure tolerance suffices.

FAQ
What output protocol does the MLX90377GVE-ADB-230-TU support?
The MLX90377GVE-ADB-230-TU is factory-configured exclusively for SENT output with 3 μs tick time per SAE J2716 APR2016. It does not support analog, PWM, or SPC modes - the output protocol is fixed at manufacture and cannot be reprogrammed by the end user.
Is the MLX90377GVE-ADB-230-TU pin-compatible with other MLX90377 variants?
No - the MLX90377GVE-ADB-230-TU uses the 3-terminal SMP-3 package, which is physically and electrically distinct from SOIC-8 (8-pin), TSSOP-16 (16-pin), or DMP-4 (4-pin) variants. Pin count, layout, and internal decoupling differ; PCB redesign is required for substitution.
Does the MLX90377GVE-ADB-230-TU require external decoupling capacitors?
No. The MLX90377GVE-ADB-230-TU in SMP-3 package integrates decoupling capacitance internally, eliminating the need for external VDD/VDEC capacitors. This is confirmed in datasheet section 16.4 and package specification 19.4.
What functional safety level does the MLX90377GVE-ADB-230-TU achieve?
The MLX90377GVE-ADB-230-TU is ISO 26262 ASIL-C capable in SENT output mode and ASIL-B capable in analog mode - certified as a Safety Element out of Context (SEooC) with documented fault handling time intervals and safety mechanisms per datasheet section 15.
How does Linear Stray-Field Immune Mode benefit the MLX90377GVE-ADB-230-TU?
Linear Stray-Field Immune Mode (enabled by -2xx option code) configures the MLX90377GVE-ADB-230-TU to reject magnetic interference orthogonal to the primary sensing axis - validated for reliable operation near motors, solenoids, or adjacent sensors in compact linear position applications like pedal or suspension sensors.
