Overview
MLX90422GDC-ADD-030-SP from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing. It integrates a 3-axis Hall front end, DSP-based signal conditioning, programmable linearization (up to 17 points), SENT output per SAE J2716 APR2016, and operates from −40°C to +160°C in SOIC-8 package. It delivers robust non-contact angular measurement in automotive throttle and pedal systems.
For engineers reviewing the MLX90422GDC-ADD-030-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 pin mapping, SENT timing compliance, ASIL B safety status, AEC-Q100 Grade 0 qualification, and real-world use cases in high-reliability motion control.
Technical Context
The MLX90422GDC-ADD-030-SP uses Triaxis® Hall technology to measure Bx, By, and Bz components simultaneously, enabling configurable axis selection for rotary or linear position calculation. Its on-chip DSP performs real-time angle computation with user-programmable transfer characteristics.
It outputs SENT frames in Single Secure Sensor A.3 (H.4) format with fixed 3 µs tick time, 287-tick frame length, and built-in diagnostics including broken-wire detection. The device supports continuous synchronous acquisition mode with 1.32–2.03 ms average latency and 2.71–3.61 ms worst-case step response under Filter 1/2 settings.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | Accepts 4.5–5.5 V; internal regulator generates 3.3 V analog rail (VDEC) for sensor front end. |
| 2 - Test1 | Factory test pin | Internally grounded in application mode; tie to GND on PCB for EMC improvement. |
| 3 - Test2 | Factory test pin | Internally grounded in application mode; tie to GND on PCB for EMC improvement. |
| 4 - N.C. | No connection | Not bonded; must be connected to GND to reduce EMI coupling and improve noise immunity. |
| 5 - OUT | SENT open-drain output | Drives external pull-up (10–55 kΩ); outputs 0.5 V low / 4.1 V high compliant with SAE J2716. |
| 6 - N.C. | No connection | Not bonded; must be connected to GND to reduce EMI coupling and improve noise immunity. |
| 7 - VDEC | Internal analog voltage decoupling | Requires 100 nF ceramic capacitor to GND; stabilizes internal 3.3 V reference for ADC and DSP. |
| 8 - VSS | Ground reference | Main digital/analog return path; low-inductance connection to PCB ground plane required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90421GDC-ADD-030-SP | Single-die Triaxis® sensor with identical SOIC-8 package and SENT A.3 output, but lacks dual-die redundancy and ASIL B certification. | Suitable for non-safety-critical linear position tasks; not qualified for ASIL B systems or redundant architectures. | Select when cost sensitivity outweighs functional safety requirements and failure modes do not require hardware-level redundancy. |
| AMS AS5055A-BQFT | 12-bit Hall-based rotary encoder with SPI/I²C interface; no SENT output, no ASIL B certification, and narrower temp range (−40°C to +125°C). | Used in industrial HMI and consumer robotics; lacks automotive qualification and SENT protocol support for ECU integration. | Choose only if SPI interface is preferred and system does not require automotive-grade temperature performance or safety certification. |
Compared with MLX90422GDC-ADD-030-SP, MLX90421GDC-ADD-030-SP offers lower cost but omits ASIL B compliance and dual-die fault tolerance, while AMS AS5055A-BQFT provides higher resolution but lacks SENT output, AEC-Q100 Grade 0 rating, and high-temp capability-making MLX90422GDC-ADD-030-SP the only option meeting full automotive safety, interface, and environmental requirements.

FAQ
What is the operating temperature range of the MLX90422GDC-ADD-030-SP?
The MLX90422GDC-ADD-030-SP is qualified for operation from −40°C to +160°C ambient temperature per AEC-Q100 Grade 0. It supports short-term exposure up to +180°C in DMP-4, SMP-3, and SMP-4 packages, but the SOIC-8 variant (MLX90422GDC-ADD-030-SP) is rated for continuous operation up to +160°C. This makes it suitable for under-hood applications such as throttle bodies and transmission sensors.
Does the MLX90422GDC-ADD-030-SP support SENT protocol compliance with SAE J2716?
Yes, the MLX90422GDC-ADD-030-SP implements SENT output fully compliant with SAE J2716 APR2016, using the Single Secure Sensor A.3 (H.4) format. It features fixed 3 µs tick time, 287-tick frame length, and supports both synchronous and asynchronous acquisition modes. The SENT output includes CRC, diagnostics, and user-defined data fields as defined in the standard.
Is the MLX90422GDC-ADD-030-SP certified for functional safety standards?
Yes, the MLX90422GDC-ADD-030-SP is certified as an ISO 26262 Safety Element out of Context (SEooC) at ASIL B. It includes integrated safety mechanisms such as watchdog timers, memory ECC, and diagnostic cycles (DCTANA = 10.4 ms, DCTDIG = 19.7 ms), enabling its use in ASIL B systems without requiring additional hardware redundancy.
What package type and pin count does the MLX90422GDC-ADD-030-SP use?
The MLX90422GDC-ADD-030-SP uses the SOIC-8 (DC) package - an 8-pin, surface-mount, RoHS-compliant small-outline integrated circuit with 1.27 mm pitch and 4.9 mm × 3.9 mm body dimensions. Pin 5 is the SENT open-drain output; pins 2, 3, 4, and 6 are factory test or no-connect terminals that must be tied to ground for EMC compliance.
Can the MLX90422GDC-ADD-030-SP be programmed for custom transfer characteristics?
Yes, the MLX90422GDC-ADD-030-SP supports user-programmable linear transfer characteristics with up to 17 calibration points stored in NVRAM. This allows compensation for mechanical nonlinearities in throttle linkages, pedal arms, or steering columns. Programming is performed via Melexis' PTC interface using standard SENT-compatible tools and requires no external components.
