Product details
Overview
MLX90371GVD-EAC-300-SP from Melexis is a dual-die Triaxis® absolute position sensor in SMP-4 PCB-less package, delivering ratiometric analog outputs with 12-bit DAC resolution, ±1° intrinsic XY linearity error, and ISO26262 ASIL-B Safety Element out of Context compliance for automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90371GVD-EAC-300-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SMP-4 package pin mapping, programmable transfer characteristics, magnetic field requirements (70 mT min BX/BY), and safety-critical diagnostic configuration options.
Technical Context
The MLX90371GVD-EAC-300-SP integrates two independent Triaxis® sensing dies in a single SMP-4 mold, each measuring all three orthogonal magnetic flux components (BX, BY, BZ) to compute absolute angular or linear position without mechanical contact. It operates across -40°C to +160°C with 4.5–5.5 V supply and supports Standard/Legacy mode with multi-point calibration (4/8/16/32 segments).
Its on-chip signal processing includes FIR filtering (3 modes), exponential moving average, programmable gain limits (GAINMIN/GAINMAX), clamping (CLAMPLOW/CLAMPHIGH), and diagnostics for field-too-low/high, broken-wire detection, and intelligent watchdog. Output latency is 440–462 μs; step response ranges from 1127 μs (FIR1) to 5099 μs (FIR1111) depending on filter selection.

Pinout & Package
SMP-4 is a PCB-less, single-mold package designed for direct housing/leadframe integration. Its compact footprint (3.2 × 3.2 mm) and side-by-side dual-die layout provide two independent analog outputs (OUT1/OUT2) sharing VDD and VSS, eliminating board space and solder joints while improving mechanical robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Analog output channel 1 | Programmable ratiometric voltage (0–100% VDD); used for primary position signal or redundancy path. |
| 2 - VSS | Ground reference | Common return for both dies and internal analog/digital circuitry; critical for noise immunity in high-EMI environments. |
| 3 - VDD | Power supply input | 4.5–5.5 V supply with reverse-voltage protection (-7 V, <48 h); powers both dies and integrated diagnostics. |
| 4 - OUT2 | Analog output channel 2 | Independent ratiometric output; enables dual-signal architectures for fault-tolerant systems per ISO26262. |
| a - TEST1 | Factory test terminal | Not user-accessible in final application; used during wafer sort and final test for parametric verification. |
| b - INPUT | Diagnostic enable input | Configures diagnostic behavior (e.g., forced self-test activation); pulled internally if unused. |
| c - TEST2 | Factory test terminal | Reserved for production test only; no functional role in end-user operation. |
Key Features

IC Role / Device Role / Timing Role: Solid-state absolute position sensor delivering ratiometric analog output compatible with existing potentiometer interface circuits. Use Value: No moving parts or wiper contact eliminates wear-out failure mode; SMP-4 mounting enables direct integration into metal housings without PCB flexure concerns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVD-EAC-300-SP | Single-die SMP-4 variant with identical pinout but only one analog output (OUT1); lacks dual-output redundancy. | Suitable for cost-sensitive ASIL-A or non-safety applications where single-channel operation suffices. | Select when dual-output fault tolerance is unnecessary and BOM cost reduction is prioritized over functional safety headroom. |
| MLX90393ELH-ABA-000-TU | Triaxis® 3-axis magnetic sensor in TSSOP-16 package; digital I²C/SPI output only; no analog output or SMP-4 packaging. | Used in low-power, space-constrained consumer or industrial applications requiring digital position data, not ratiometric analog. | Choose only if system architecture mandates digital interface and PCB-based mounting; incompatible with SMP-4 mechanical integration or analog signal chain. |
Compared with MLX90371GVD-EAC-300-SP, the MLX90372 offers lower cost and same package but sacrifices redundancy, while the MLX90393 provides higher flexibility in digital domain integration yet requires redesign of signal conditioning and mechanical mounting - making MLX90371GVD-EAC-300-SP uniquely suited for safety-critical, analog-output, PCB-less automotive deployments.
