Product details
Overview
MLX90425GVE-ABA-600-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute angular rotary sensing up to 360°, featuring ratiometric analog or PWM output, ±1 T magnetic field range, -40°C to +160°C operating temperature, and AEC-Q100 Grade 0 qualification. It decodes on-axis magnet rotation using differential Z-axis field sensing and supports post-assembly programming for linearization.
For engineers reviewing the MLX90425GVE-ABA-600-RE datasheet, pinout, applications, or equivalent options, key selection criteria include stray-field robustness, ISO26262 ASIL-B safety compliance, SMP-3 package footprint, programmable 17-point transfer characteristic, and high-temperature operation up to +160°C in automotive pedal and throttle systems.
Technical Context
The MLX90425GVE-ABA-600-RE integrates a Triaxis® Hall front end, analog-to-digital signal conditioner, and DSP-based signal processing engine optimized for absolute angle extraction from rotating magnets. Its architecture enables stray-field immunity via differential Z-axis field sensing and supports real-time linearization through 17-point programmable piecewise-linear (PWL) transfer functions.
It operates in continuous acquisition mode with 512 µs internal angle measurement period and delivers output via ratiometric analog voltage (0.5–99% VDD) or PWM (100–2000 Hz), both configurable post-assembly. Built-in diagnostics include broken-wire detection on VDD/VSS lines and fail-safe state activation within 5–33 ms after digital fault detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic angular position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90425GDC-ABA-600-RE | SOIC-8 package (5.0 × 4.0 mm), 2× larger footprint, requires external decoupling capacitors | Better thermal dissipation and manual soldering compatibility; less suitable for ultra-compact modules | Select when board space permits and higher power handling or reworkability is prioritized over miniaturization |
| MLX90425GVS-ABA-600-RE | DMP-4 package (3.0 × 3.0 mm), pin-to-pin compatible with legacy Triaxis® sensors, dual ground pins | Enables drop-in replacement in existing designs using prior-generation Melexis position sensors | Select for design refreshes where mechanical compatibility with older PCB layouts is required |
Compared with MLX90425GVE-ABA-600-RE, the SOIC-8 variant offers greater thermal margin and layout flexibility but increases board area by 165%, while the DMP-4 version preserves legacy pinout and grounding topology-making it ideal for cost-sensitive redesigns rather than new miniaturized platforms.

FAQ
What is the package type and dimensions of the MLX90425GVE-ABA-600-RE?
The MLX90425GVE-ABA-600-RE uses the SMP-3 package: a PCB-less single-mold compact form factor measuring 3.0 mm × 2.5 mm × 0.8 mm. It integrates decoupling capacitors internally, eliminating the need for external bypass components and reducing PCB footprint. This package is RoHS-compliant and optimized for high-volume automotive sensor modules where space and reliability are critical.
Does the MLX90425GVE-ABA-600-RE support both analog and PWM outputs simultaneously?
No, the MLX90425GVE-ABA-600-RE supports either ratiometric analog output or PWM output-not both concurrently. The output mode is configured during programming via the end-user programmable interface. Once set, the device operates exclusively in that mode until reprogrammed. The analog output delivers 0.5–99% VDD proportional to angle; the PWM output provides duty cycle modulation from 0% to 100% at 100–2000 Hz.
What safety certifications apply to the MLX90425GVE-ABA-600-RE?
The MLX90425GVE-ABA-600-RE is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0 (−40°C to +160°C). These certifications validate its use in automotive safety-related systems such as electronic throttle control and brake-by-wire, with built-in diagnostics including memory ECC, CRC-protected configuration, watchdog timers, and fail-safe output states.
Can the MLX90425GVE-ABA-600-RE operate above 160°C ambient temperature?
Yes-the MLX90425GVE-ABA-600-RE supports high-temperature extension up to +180°C ambient for ≤250 hours, but only in SMP-3, DMP-4, and SMP-4 packages. Electrical specifications remain valid under this condition with supply voltage limited to 5.5 V. The SOIC-8 and TSSOP-16_EP variants are not rated for this extended range. Full details appear in Section 4.1 and Table 10 of the datasheet.
How is linearization implemented in the MLX90425GVE-ABA-600-RE?
The MLX90425GVE-ABA-600-RE implements linearization via a 17-point programmable piecewise-linear (PWL) transfer function stored in NVRAM. This allows users to calibrate the sensor post-assembly-correcting for magnet nonlinearity, mechanical eccentricity, and air-gap variations. The DSP applies real-time interpolation between points, achieving ±0.5° typical INL without external compensation circuitry.
