Product details
Overview
MLX90422GVE-ADD-030-TU 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, and operation from −40 °C to +160 °C in SMP-3 package. It uses Bx/By/Bz field components for contactless angular measurement up to 360°, with ISO 26262 ASIL B safety element out of context and AEC-Q100 Grade 0 qualification.
For engineers reviewing the MLX90422GVE-ADD-030-TU datasheet, pinout, applications, or equivalent options, key selection criteria include SENT frame timing (861–905 μs), 1.32–2.03 ms latency in synchronous mode, dual-die redundancy capability, magnetic field sensitivity (Bz up to 126 mT), and PCB-less SMP-3 footprint compatibility with automotive pedal/throttle position systems.
Technical Context
The MLX90422GVE-ADD-030-TU integrates a Triaxis® Hall front end, analog-to-digital signal conditioner, DSP-based signal processing engine, and SENT output driver. Its architecture enables absolute angle calculation using configurable combinations of Bx, By, and Bz magnetic field components, supporting both X-Y and X-Z sensing modes with user-defined IMC gain (GIMC = 1.19).
It operates in continuous synchronous acquisition mode by default, delivering fixed-length SENT frames (287 ticks, 3 μs/tick) with two angle acquisitions per frame and 16-point DSP linearization. The device supports programmable diagnostics, filtering (three selectable filter types), and safe startup time (5–33 ms), with internal regulated VDEC = 3.2–3.4 V and supply current of 7.5–10.0 mA at 4.5–5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT per SAE J2716 APR2016, A.3 (H.4) format with pause pulse - ensures automotive ECU compatibility and diagnostic message embedding. |
| Operating Temperature | −40 °C to +160 °C - qualified for under-hood automotive applications including throttle and pedal sensors. |
| Supply Voltage | 4.5 V to 5.5 V - stable operation across automotive battery variations; start-up threshold at 3.85–4.15 V. |
| Latency (Synchronous) | 1.32–2.03 ms - deterministic response time critical for real-time closed-loop control in steering or transmission systems. |
| Magnetic Sensitivity | Bz up to 126 mT, Bx/By up to 70 mT - enables robust detection with small magnets in compact mechanical layouts. |
| Linearization Points | Up to 17 programmable points - allows precise correction of nonlinearity across full 0–360° rotation range. |
| Safety Certification | ISO 26262 ASIL B Safety Element out of Context - supports integration into ASIL B or lower automotive safety architectures without additional decomposition. |
Pinout & Package
SMP-3 is a PCB-less single-mold package with 3 terminals: VDD (supply), OUT (open-drain SENT output), and VSS (ground). Its compact form factor enables direct mounting on flexible substrates or metal leads in space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VDD | Power supply input | Accepts 4.5–5.5 V; internal regulator generates 3.2–3.4 V analog rail (VDEC) for sensor core. |
| 2: OUT | SENT serial output | Open-drain digital output compliant with SAE J2716; requires external pull-up to Vext (≤ VDD); supports broken-wire diagnostics. |
| 3: VSS | Ground reference | Common return path for supply and signal; used in passive diagnostic detection (BVSSPU = 99.5–100% VDD on open-circuit). |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Technology | Simultaneous measurement of Bx, By, and Bz enables true 3D magnetic field analysis for absolute position without mechanical cam or gear constraints. |
| Programmable Transfer Characteristic | 17-point user-defined lookup table allows precise calibration to mechanical nonlinearity in throttle linkages or pedal arms. |
| SENT Output with Diagnostics | Embedded error codes, CRC, and user-defined values in every frame support functional safety monitoring and predictive maintenance in ASIL B systems. |
| AEC-Q100 Grade 0 Qualification | Validated for 160 °C ambient operation - meets requirements for engine bay and transmission control unit placement. |
| PCB-less SMP-3 Package | Direct lead-frame mounting eliminates PCB assembly steps and reduces thermal resistance for high-temperature reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90421GVE-ADD-030-TU | Single-die variant with identical SMP-3 package, SENT output, and 16-point linearization - lacks dual-die redundancy and ASIL B SEooC certification. | Targeted at non-safety-critical industrial position sensing where cost optimization outweighs functional safety requirements. | Select when ASIL B compliance and fault-tolerant diagnostics are not required; shares same footprint and programming interface. |
| AMS AS5600-WSCT | I²C output instead of SENT; 12-bit resolution vs. SENT-encoded 12-bit+ diagnostics; no AEC-Q100 or ASIL B qualification; operates to +85 °C only. | Suitable for consumer or industrial encoders where automotive-grade temperature and safety certification are unnecessary. | Choose for prototyping or non-automotive designs needing I²C simplicity; not drop-in replaceable due to protocol, temp, and safety gaps. |
Compared with MLX90422GVE-ADD-030-TU, the MLX90421GVE-ADD-030-TU offers identical packaging and basic functionality at lower cost but omits safety mechanisms and redundancy, while the AMS AS5600-WSCT provides simpler I²C interfacing yet fails to meet automotive thermal, reliability, or functional safety thresholds required for throttle or pedal use.
