Product details

Overview

MLX90426GVE-ACB-630-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary angle measurement up to 360°, featuring SENT output per SAE J2716 APR2016, AEC-Q100 Grade 0 qualification (−40°C to +160°C), ISO26262 ASIL B safety element out of context, and robust stray-field immunity. It decodes angular position from on-axis rotating magnets in non-contacting pedal, throttle, and steering wheel sensors.

For engineers reviewing the MLX90426GVE-ACB-630-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (SMP-3), SENT timing compliance, programmable 17-point linearization, high-temperature operation up to +180°C (SMP-3), and functional safety architecture details critical for automotive position sensing design.

Technical Context

The MLX90426GVE-ACB-630-RE integrates a Triaxis® Hall front end sensitive to Z-axis differential magnetic field, an analog-to-digital signal conditioner, and a DSP performing real-time piecewise-linear (PWL) interpolation across up to 17 user-programmable points. Its SENT output supports both Single Secure Sensor A.3 (H.4) and Dual Throttle Position Sensor A.1 (H.1) frame formats with embedded CRC, error codes, and diagnostics.

It operates in continuous synchronous acquisition mode by default (fixed 294-tick SENT frame, 882–927 µs refresh), delivering average latency of 1.32–2.03 ms and step response of 2.25–3.64 ms depending on filter configuration. The SMP-3 package embeds decoupling capacitors and enables high-temperature extension to +180°C for limited duration.

Equivalent & Alternatives

The following parts are listed as comparable options for similar magnetic position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90426GDC-ACB-630-RE	SOIC-8 package (8-pin) with separate VDEC decoupling pin; no integrated capacitors; lower thermal resistance than SMP-3	Preferred for designs requiring manual decoupling optimization or legacy SOIC footprint compatibility	Select when board layout allows discrete capacitor placement and thermal management prioritizes junction cooling over miniaturization
MLX90426GVD-BAB-630-RE	SMP-4 stacked-die package with dual independent outputs (OUT1/OUT2); higher current draw (17–24 mA); redundant architecture	Required for ASIL D systems needing dual-channel comparison or fault-tolerant redundancy	Select only when dual-output redundancy is mandated by system safety architecture-not a drop-in replacement for single-output use cases

Compared with MLX90426GVE-ACB-630-RE, the SOIC-8 variant offers greater thermal flexibility but increases BOM count and layout area, while the SMP-4 stacked-die version adds hardware-level redundancy at the cost of doubled supply current and incompatible pinout-neither is pin-compatible, and selection depends strictly on thermal, safety, and packaging constraints.

How many programmable points does the transfer characteristic support on MLX90426GVE-ACB-630-RE?

The MLX90426GVE-ACB-630-RE supports up to 17 programmable points for piecewise-linear (PWL) transfer characteristic calibration. This enables precise compensation of magnet nonlinearity, mechanical eccentricity, and temperature-induced drift during end-of-line programming-documented in Sections 11 and 12.2 of the datasheet.

Is MLX90426GVE-ACB-630-RE certified for functional safety applications?

Yes. The MLX90426GVE-ACB-630-RE is qualified as an ISO26262 ASIL B Safety Element out of Context (SEooC), with documented safety mechanisms including watchdog timers, ECC memory protection, diagnostic cycle monitoring, and fail-safe output behavior.
