Product details
Overview
MLX90422GGO-ADD-030-TU from Melexis is a dual-die Triaxis® Hall-based absolute rotary position sensor IC in TSSOP-16 package, delivering SENT output per SAE J2716 APR2016, operating from −40 °C to +160 °C, with ISO 26262 ASIL B safety certification and AEC-Q100 Grade 0 qualification - used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90422GGO-ADD-030-TU datasheet, pinout, applications, or equivalent options, key selection factors include dual-die redundancy architecture, SENT frame timing (861–905 μs), programmable 17-point linearization, ±126 mT Z-axis magnetic sensitivity, and high-temperature operation up to +160 °C.
Technical Context
The MLX90422GGO-ADD-030-TU integrates two independent Triaxis® Hall front ends, each with dedicated VDD/VSS/VDEC pins and separate SENT outputs (OUT1/OUT2), enabling full functional redundancy for safety-critical applications. Its DSP performs real-time 3D magnetic vector processing (Bx, By, Bz) to compute absolute angular position without external magnets or gears.
It supports both synchronous (fixed-frame) and asynchronous (variable-frame) SENT modes, with configurable diagnostics including broken-wire detection on VDD/VSS, CRC error reporting, and programmable field thresholds (BTH_LOW: 2–30 mT; BTH_HIGH: 70–126 mT). The device uses internal 24 MHz main clock with ±5% tolerance and 3 μs fixed tick time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - stable operation across automotive battery transients; dual-die version draws ≤17 mA total. |
| Output Protocol | SENT per SAE J2716 APR2016 - supports A.3 (H.4) format with pause pulse, 287-tick frames (861–905 μs). |
| Operating Temp | −40 °C to +160 °C - qualified for under-hood automotive use; junction limit +175 °C. |
| Magnetic Sensitivity | Bz up to ±126 mT - enables robust sensing with small, low-cost magnets in rotary configurations. |

| Package | TSSOP-16 (GO) - dual-die layout with isolation resistance ≥4 MΩ between dies for fault containment. |
Pinout & Package
TSSOP-16 (GO) package provides full redundancy: two independent sensor dies sharing no analog or digital resources except PCB ground plane. Requires separate decoupling capacitors per die (VDEC1/VDEC2) and isolated supply routing for highest fault tolerance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - must be connected to local 100 nF ceramic caps near each VDD pin. |
| 2, 10 | VSS1 / VSS2 | Independent ground returns - recommended to route separately to minimize cross-die noise coupling. |
| 3, 11 | VDD1 / VDD2 | Independent power inputs - enables supply monitoring per die and fault isolation during overvoltage events. |
| 6, 15 | OUT2 / OUT1 | Separate open-drain SENT outputs - allows dual-channel validation or fail-safe voting logic in host ECU. |
| 4, 5, 12, 13, 7, 8, 14, 16 | Test11 / Test22 / Test12 / Test21 / N.C. | Factory test pins - internally grounded in application mode; connect to PCB ground for EMC compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die redundancy | Two physically independent sensor dies in one TSSOP-16 package - eliminates single-point failure risk in ASIL B systems. |
| Triaxis® 3D sensing | Simultaneous measurement of Bx, By, Bz - enables absolute angle calculation from magnet rotation without mechanical stops or calibration. |
| Programmable linearization | Up to 17-point user-defined transfer curve - compensates for non-ideal magnet fields and mechanical tolerances in production assemblies. |
| SENT diagnostics | Embedded CRC, broken-wire detection (VDD/VSS), and configurable field thresholds - reduces need for external diagnostic circuitry. |
| High-temp operation | Validated operation at +160 °C ambient - supports placement near engines, transmissions, and exhaust components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90421GGO-ADD-030-TU | Single-die variant in same TSSOP-16 package - lacks dual-die redundancy and inter-die isolation. | Not suitable for ASIL B systems requiring hardware redundancy; lower cost for non-safety-critical throttle sensors. | Select when functional safety certification is not required and BOM cost reduction is prioritized over fault tolerance. |
| AMS AS5055A-BQFT | Single-die Hall-based encoder with SPI/I²C output - no SENT support, no ASIL B certification, max temp +125 °C. | Limited to non-automotive industrial position sensing; requires external microcontroller for SENT conversion. | Choose only for cost-sensitive, non-automotive applications where SENT interface and high-temp operation are unnecessary. |
Compared with MLX90422GGO-ADD-030-TU, the MLX90421GGO-ADD-030-TU reduces system-level safety mechanisms but increases risk of undetected latent faults, while the AMS AS5055A-BQFT requires additional signal conditioning and fails to meet automotive thermal or protocol requirements - making MLX90422GGO-ADD-030-TU the only drop-in solution for ASIL B rotary sensing at +160 °C.

FAQ
What is the maximum ambient temperature rating for MLX90422GGO-ADD-030-TU?
The MLX90422GGO-ADD-030-TU is rated for continuous operation from −40 °C to +160 °C ambient temperature, with junction temperature limited to +175 °C. It supports short-duration exposure up to +180 °C in SMP/DMP packages, but the TSSOP-16 (GO) variant is validated only to +160 °C per AEC-Q100 Grade 0 specification. This makes MLX90422GGO-ADD-030-TU suitable for under-hood automotive locations including throttle bodies and transmission housings.
Does MLX90422GGO-ADD-030-TU support both synchronous and asynchronous SENT modes?
Yes, MLX90422GGO-ADD-030-TU supports both modes. In default factory configuration, it operates in synchronous SENT mode with fixed 287-tick frames (861–905 μs), where angle acquisition is aligned to frame start. It can be reprogrammed to asynchronous mode with variable frame length (up to 270 ticks), enabling lower average latency (as low as 0.83 ms) at the cost of jitter. Both modes comply with SAE J2716 APR2016 and retain full diagnostic coverage - a key capability of MLX90422GGO-ADD-030-TU.
How does the dual-die architecture of MLX90422GGO-ADD-030-TU improve functional safety?
The MLX90422GGO-ADD-030-TU implements physically independent sensor dies with separate power, ground, decoupling, and output pins - achieving ≥4 MΩ isolation resistance between dies. This architecture enables cross-checking of SENT outputs, detection of die-specific faults (e.g., broken wire, magnetic saturation), and continued operation after single-die failure. As a result, MLX90422GGO-ADD-030-TU meets ISO 26262 ASIL B as a Safety Element out of Context, eliminating need for external redundancy in the ECU.
Can MLX90422GGO-ADD-030-TU be programmed for linear position sensing?
Yes, MLX90422GGO-ADD-030-TU supports both angular rotary and linear position modes via end-user programming. In linear mode, it calculates position from magnetic field gradients along one axis (e.g., Bx or By), using the same Triaxis® front end and 17-point programmable transfer characteristic. The device's magnetic specification confirms usable flux density norms down to 10 mT in X-Y mode - enabling compact, low-cost linear implementations such as ride height or suspension travel sensors without modifying MLX90422GGO-ADD-030-TU hardware.
What are the key electrical requirements for the SENT output of MLX90422GGO-ADD-030-TU?
The MLX90422GGO-ADD-030-TU SENT outputs (OUT1/OUT2) are open-drain with 0.5 V low-state voltage at 0.52 mA load and 4.1 V high-state voltage at 0.10 mA load. It requires an external pull-up resistor (10–55 kΩ) to Vext = VDD, and supports SENT frame timing with 3 μs fixed tick time, 287-tick frames, and pause pulses. These parameters ensure compatibility with standard automotive SENT receivers and eliminate need for level-shifting or timing recalibration - a core design feature of MLX90422GGO-ADD-030-TU.
