Product details
Overview
MLX90422GGO-ADD-030-SP from Melexis is a dual-die Triaxis® Hall-based absolute rotary position sensor IC in TSSOP-16 package, delivering SENT A.3 (H.4) output with 1.75 ms average latency, ±0.5° angular accuracy over -40°C to +160°C, and ISO 26262 ASIL B safety certification for automotive throttle and steering applications.
For engineers reviewing the MLX90422GGO-ADD-030-SP datasheet, pinout, applications, or equivalent options, this page provides verified pin definitions, SENT timing compliance, redundancy architecture details, magnetic field sensitivity thresholds, and functional safety mechanisms specific to the GO-package dual-die variant.
Technical Context
The MLX90422GGO-ADD-030-SP implements full hardware redundancy via two independent dies in one TSSOP-16 package, each with dedicated supply (VDD1/VDD2), ground (VSS1/VSS2), decoupling (VDEC1/VDEC2), and SENT outputs (OUT1/OUT2), enabling cross-die diagnostics and fault-tolerant operation per ISO 26262 ASIL B requirements.
It uses Triaxis® sensing to measure Bx, By, and Bz components simultaneously, supports programmable linearization up to 17 points, and delivers SENT frames with embedded CRC, diagnostic codes, and user-defined values - all synchronized to a 24 MHz internal clock with ±3.5% thermal drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT A.3 (H.4) compliant per SAE J2716 APR2016, enabling direct interface with automotive ECUs without external protocol translation. |
| Angular Accuracy | ±0.5° over full 0–360° range at -40°C to +160°C, validated for pedal and throttle position feedback where closed-loop control stability depends on sub-degree repeatability. |
| Latency | 1.75 ms typical average latency in synchronous mode, critical for real-time torque estimation and fast-acting actuator control loops. |
| Supply Range | 4.5 V to 5.5 V, with overvoltage detection at 6.25 V and undervoltage lockout at 3.75 V - ensures robust operation under automotive battery transients. |
| Magnetic Sensitivity | Supports Bz up to 126 mT and in-plane flux (Bx/By) up to 70 mT, allowing compact magnet placement in space-constrained assemblies like EPS modules. |
| Safety Certification | ISO 26262 ASIL B Safety Element out of Context (SEooC), with integrated watchdogs, memory ECC, and diagnostic cycle times (DCTANA = 10.4 ms, DCTDIG = 19.7 ms). |
| Operating Temp | -40°C to +160°C ambient, extended to +180°C for ≤250 h in SMP/DMP packages - meets Grade 0 AEC-Q100 requirements for under-hood deployment. |
Pinout & Package
TSSOP-16 (GO) package with 0.65 mm pitch, 5.0 mm × 4.4 mm footprint, and dual-die layout enabling physical isolation between redundant signal paths. Thermal resistance θJA = 120°C/W (JEDEC Std 22).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require separate 100 nF ceramic capacitors to minimize noise coupling between redundant channels. |
| 2, 10 | VSS1 / VSS2 | Independent ground terminals per die - must be routed separately to avoid shared impedance faults compromising ASIL B fault detection. |
| 3, 11 | VDD1 / VDD2 | Isolated supply inputs per die - enable independent power monitoring and supply-failure discrimination in safety-critical systems. |
| 6, 15 | OUT2 / OUT1 | Redundant SENT outputs - support cross-checking, voting logic, or fail-safe fallback to single-channel mode upon detected mismatch. |
| 4, 5, 12, 13 | Test11 / Test22 / Test12 / Test21 | Factory test pins - internally grounded in application mode; tie to PCB ground for EMC compliance and noise immunity. |
| 7, 8, 14, 16 | N.C. | No-connect terminals - must remain unconnected per design; floating N.C. pins are specified to prevent parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die redundancy | Two fully independent sensor dies in one TSSOP-16 package with isolated power, ground, and output paths - enables hardware-level fault containment per ASIL B requirements. |
| Programmable linearization | Up to 17-point user-defined transfer curve - allows precise compensation for non-ideal magnet geometry or mechanical hysteresis in throttle linkages. |
| SENT diagnostic framing | Embedded CRC, error flags, and configurable diagnostic nibbles - eliminates need for external validation logic in ECU-side SENT receivers. |
| Triaxis® 3-axis sensing | Simultaneous Bx, By, Bz measurement - enables absolute angle calculation from off-axis magnet motion, reducing mechanical alignment tolerance burden. |
| High-temp operation | Validated operation at +160°C ambient, +175°C junction - supports placement near exhaust manifolds or turbochargers without external cooling. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |

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 |
|---|---|---|---|
| MLX90422GDC-ADD-030-RE | SOIC-8 single-die variant with identical SENT protocol, accuracy, and temperature rating but no hardware redundancy. | Lacks dual-die isolation and cross-die diagnostics - suitable for non-ASIL B applications like HVAC damper control. | Select when cost and board space are constrained and functional safety requirements do not mandate hardware redundancy. |
| MLX90422GVS-ADD-030-RE | DMP-4 PCB-less dual-mold package with same dual-die architecture and SENT output, but 4-pin leadframe instead of 16-pin TSSOP. | Smaller footprint (3.0 × 2.5 mm) and lower profile - optimized for ultra-compact modules like transmission shift-by-wire actuators. | Select when mechanical integration requires minimal Z-height and board area, accepting trade-offs in thermal dissipation and manual rework accessibility. |
Compared with MLX90422GGO-ADD-030-SP, the SOIC-8 alternative reduces cost and complexity but forfeits ASIL B-compliant redundancy, while the DMP-4 variant maintains dual-die safety integrity in a miniaturized form factor ideal for space-limited mechatronic assemblies.
