Product details

Overview

MLX90422GVS-ADD-030-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing, featuring SENT output per SAE J2716 APR2016, programmable 17-point linear transfer characteristic, ISO26262 ASIL B safety element out of context, and operation from −40°C to +160°C in DMP-4 package. It delivers robust non-contacting angular measurement up to 360° in automotive pedal and throttle systems.

For engineers reviewing the MLX90422GVS-ADD-030-RE datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance (A.3/H.4), DMP-4 PCB-less packaging, ±10 mT useful magnetic flux density norm, 1.32–2.03 ms average latency in synchronous mode, and AEC-Q100 Grade 0 qualification.

Technical Context

The MLX90422GVS-ADD-030-RE integrates a Triaxis® Hall front end sensitive to B_x, B_y, and B_z magnetic components, an analog-to-digital signal conditioner, and a DSP enabling axis-selectable absolute position calculation. Its programmable sensing mode supports X-Y, X-Z, or Y-Z configurations based on magnet orientation.

It operates in continuous synchronous SENT mode by default: fixed 3 μs tick time, 287-tick frame (861–905 μs), dual angle acquisitions per frame, and 16-point DSP linearization. Startup time to first valid angle is 5.93 ms, with safe startup window up to 33 ms.

Pinout & Package

DMP-4 (Dual Mold Package) is a PCB-less, 4-pin surface-mount package with integrated decoupling capacitance, optimized for space-constrained automotive sensors requiring high EMC immunity and mechanical robustness.

Pin/Terminal	Circuit Role	Design Meaning
1	VSS	Ground reference for analog and digital domains; must be connected to low-impedance chassis ground
2	VDD	Primary supply input (4.5–5.5 V); powers internal regulator generating 3.3 V analog rail
3	OUT	Open-drain SENT output; requires external pull-up to V_ext (V_DD); drives standard automotive diagnostic receivers
4	VSS	Second ground terminal; improves current return path symmetry and reduces EMI coupling

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90421GVS-ADD-030-RE	Single-die variant with identical DMP-4 package, SENT A.3 output, and 16-point linearization but lacks ASIL B certification	Targeted at non-safety-critical industrial position sensing where functional safety is not mandated	Select when cost optimization is prioritized and ISO26262 compliance is unnecessary
AMS AS5600-WSCT	I²C output (not SENT), 12-bit resolution, no ASIL B or AEC-Q100 qualification, max operating temp +85°C	Suitable for consumer electronics or lab equipment; not rated for automotive under-hood deployment	Choose only for non-automotive designs requiring simple I²C interface and lower temperature range

Compared with MLX90422GVS-ADD-030-RE, the MLX90421GVS-ADD-030-RE offers identical form-factor and core sensing capability but omits safety mechanisms required for ASIL B decomposition, while the AMS AS5600-WSCT lacks automotive qualification, SENT output, and high-temperature operation-making neither a drop-in replacement.

FAQ

What is the SENT protocol configuration used by the MLX90422GVS-ADD-030-RE?

The MLX90422GVS-ADD-030-RE uses SENT with pause pulse per SAE J2716 APR2016, defaulting to A.3 (H.4) format with 287-tick frames (861–905 μs), 3 μs fixed tick time, and two angle acquisitions per frame. This configuration ensures deterministic timing for ECU synchronization and supports embedded CRC and diagnostic fields required for ASIL B compliance.

Does the MLX90422GVS-ADD-030-RE require external decoupling capacitors?

No, the MLX90422GVS-ADD-030-RE in DMP-4 package integrates decoupling capacitance internally. Pin 1 and Pin 4 are both VSS terminals providing low-inductance return paths, and no external ceramic capacitor is needed-reducing PCB area and improving reliability in high-vibration automotive environments.

How does the MLX90422GVS-ADD-030-RE achieve ASIL B compliance without redundant hardware?

The MLX90422GVS-ADD-030-RE achieves ISO26262 ASIL B as a Safety Element out of Context (SEooC) through on-chip diagnostics-including watchdog timers, memory ECC, supply/temperature monitoring, and SENT CRC validation-combined with rigorous failure mode analysis documented in Melexis' safety manual. It requires proper integration into a larger ASIL B system but contains no dual-die redundancy.

What magnetic configurations are supported by the MLX90422GVS-ADD-030-RE?

The MLX90422GVS-ADD-030-RE supports three programmable sensing modes: X-Y (in-plane), X-Z, and Y-Z (using IMC gain compensation). This allows flexible magnet placement-radial, axial, or lateral-enabling compact integration in throttle bodies, pedal arms, or suspension links without mechanical rework.

Can the MLX90422GVS-ADD-030-RE operate beyond 160°C ambient temperature?

Yes, the MLX90422GVS-ADD-030-RE in DMP-4 package is qualified for high-temperature extension up to +180°C ambient for ≤250 hours, with degraded but functional performance including reduced supply voltage range (5.5 V max) and adjusted magnetic sensitivity. This capability is explicitly validated for DMP-4, SMP-3, and SMP-4 packages per datasheet Section 4.1.
