Product details
Overview
MLX90425GVE-ABA-600-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC for absolute angular rotary sensing up to 360°, operating from −40°C to +160°C, delivering ratiometric analog or PWM output with ±0.5° typical angle accuracy and programmable 17-point linearization. It is used in automotive pedal and throttle position sensing where stray-field robustness and ASIL-B functional safety compliance are required.
For engineers reviewing the MLX90425GVE-ABA-600-SP datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (SMP-3), confirmed pin functions (VDD/OUT/VSS), real-world accuracy specs, safety certification details, and validated alternatives for pedal/throttle/steering position systems.
Technical Context
The MLX90425GVE-ABA-600-SP integrates a Triaxis® Hall front end sensitive to Z-axis differential magnetic field, an ADC, a DSP for advanced signal processing including multi-point linearization, and a programmable output stage supporting ratiometric analog or PWM modes. Its architecture enables on-axis magnet decoding without mechanical contact.
It features ISO 26262 ASIL-B Safety Element out of Context (SEooC) qualification and AEC-Q100 Grade 0 compliance, with built-in diagnostics including broken-wire detection on VDD/VSS lines and configurable fail-safe timing (e.g., 5–33 ms fail-safe state duration). The SMP-3 package embeds decoupling capacitors and supports high-temperature operation up to +180°C for limited durations.

| 3: VSS | Ground reference | Common return for supply and output; enables broken-wire diagnostics |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Enables accurate 360° absolute angle measurement using only Z-axis field from on-axis rotating magnet - no side sensing or complex magnet assemblies needed |
| 17-Point Linearization | Post-assembly programming corrects system-level nonlinearity (e.g., magnet misalignment, housing distortion), improving end-of-line accuracy without hardware changes |
| Stray-Field Robustness | Immunity to external magnetic interference up to ±1 T allows reliable operation near motors, solenoids, or adjacent sensors in dense automotive ECUs |
| Integrated Diagnostics | Built-in passive broken-wire detection on VDD/VSS lines and configurable fail-safe timing (5–33 ms) reduce need for external monitoring circuitry |
| SMP-3 Embedded Capacitors | On-package decoupling eliminates discrete 100 nF ceramic capacitors, reducing BOM count and layout sensitivity in space-constrained modules |
Applications
| Pedal Position Sensing | Throttle Position Sensing |
|---|---|
Use Scenario: Monitoring accelerator or brake pedal angular displacement in electric/hybrid powertrains under vibration, temperature cycling, and EMI exposure. IC Role / Device Role / Timing Role: Absolute 360° rotary position sensor providing real-time analog/PWM feedback to engine control unit (ECU) with <512 µs update latency. Use Value: Eliminates potentiometer wear and contact bounce; ASIL-B compliance ensures functional safety integrity for drive-by-wire systems. |

Use Value: SMP-3's molded construction resists moisture ingress; extended +180°C rating allows placement near hot exhaust components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90423GSE-AAA-600-SP | Single-die SOIC-8 variant; lacks SMP-3's embedded capacitors and +180°C extension; same 360° stray-field robustness and ASIL-B SEooC | Requires external decoupling caps; better suited for prototyping or legacy SOIC footprints | Select when board layout already accommodates SOIC-8 and thermal stress is below +160°C |
| MLX90425GVD-BAA-600-SP | Stacked-dice SMP-4 package; dual redundant outputs (OUT1/OUT2), higher supply current (17–24 mA), identical accuracy and safety certification | Designed for dual-channel redundancy in steer-by-wire or transmission position safety architectures | Select when functional redundancy per ISO 26262 is required and dual independent outputs are needed |
Compared with MLX90425GVE-ABA-600-SP, the MLX90423GSE-AAA-600-SP offers pin-compatible SOIC-8 convenience but sacrifices thermal margin and integration; the MLX90425GVD-BAA-600-SP adds hardware redundancy at the cost of higher current and dual-output complexity - making the GVE-ABA-600-SP optimal for cost-sensitive, space-constrained, single-channel ASIL-B applications like pedal sensing.

The MLX90425GVE-ABA-600-SP operates from −40°C to +160°C under standard conditions. In the SMP-3 package, it supports extended operation up to +180°C for ≤250 hours - validated for high-under-hood applications such as throttle bodies and suspension modules where ambient heat exceeds 160°C.
Does the MLX90425GVE-ABA-600-SP require external decoupling capacitors?
No. The MLX90425GVE-ABA-600-SP in SMP-3 package integrates decoupling capacitors within the mold, eliminating the need for external 100 nF ceramics. This reduces PCB area, simplifies layout, and improves reliability in high-vibration environments like pedal assemblies.
How is the MLX90425GVE-ABA-600-SP programmed for linearization?
The MLX90425GVE-ABA-600-SP supports post-assembly 17-point piecewise linear (PWL) programming via its I²C-compatible interface. Users apply known mechanical angles, capture raw sensor output, and upload correction coefficients - enabling system-level calibration without magnet or housing redesign.
Is the MLX90425GVE-ABA-600-SP certified for automotive functional safety?
Yes. The MLX90425GVE-ABA-600-SP is certified as an ISO 26262 ASIL-B Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0. Its diagnostic coverage includes broken-wire detection, clock monitoring, and configurable fail-safe timing - documented in Melexis' official Safety Manual Rev. 004.
What output protocols does the MLX90425GVE-ABA-600-SP support?
The MLX90425GVE-ABA-600-SP supports two user-selectable output modes: ratiometric analog (0.5–4.5 V, proportional to VDD) and pulse-width modulated (PWM) with frequency adjustable from 100 Hz to 2000 Hz. Both modes are programmable in-system and retain settings in NVRAM after power cycle.
