Product details
Overview
MLX90423GGO-ACA-430-RE from Melexis is a Triaxis® Hall-based monolithic magnetic position processor IC for absolute linear position sensing in legacy configurations. It delivers ratiometric analog, PWM, or SENT output with ±0.5° typical angle accuracy over -40°C to +160°C, 4.5–5.5 V supply, and stray field immunity up to 5 mT - deployed in automotive throttle and pedal position sensing.
For engineers reviewing the MLX90423GGO-ACA-430-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16 dual-die), confirmed output timing (e.g., 100–2000 Hz PWM), functional safety ASIL-B/C classification, and validated alternative options for linear legacy magnetic sensing systems.
Technical Context
The MLX90423GGO-ACA-430-RE implements full redundancy via two independent dies in TSSOP-16, each with Triaxis® Hall front-end, 12-bit ADC, DSP-based LNR (linearization), and programmable diagnostics. It supports only linear legacy magnetic configuration (–4xx option code), not 360° trough-shaft mode.
Its output stage is configurable for ratiometric analog (0–100% VDD), PWM (100–2000 Hz, ±5% tolerance), or SENT (SAE J2716 APR2016), with dedicated safety mechanisms including watchdog timers (IWD/AWD), CRC-protected frames, and broken-wire detection on VDD/VSS lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Ratiometric analog, PWM (100–2000 Hz), or SENT per SAE J2716 APR2016 - selectable per end-user programming |
| Angle Accuracy | ±0.5° typical INL over full temperature range - enables high-fidelity linear position feedback without external calibration |
| Supply Range | 4.5–5.5 V (regulated mode); supports battery operation at 6–18 V for PWM/SENT only - accommodates automotive 12 V rail variations |
| Operating Temp | −40°C to +160°C - qualified to AEC-Q100 Grade 0 for under-hood deployment |
| Stray Field Immunity | Robust to 5 mT (4 kA/m) DC stray fields per ISO 11452-8 - ensures reliable operation near motors or solenoids |
| Functional Safety | ISO 26262 SEooC; ASIL-C for SENT/PWM, ASIL-B for analog - supports safety-critical automotive subsystems |
| Package | TSSOP-16 (dual-die full redundancy) - provides hardware-level fault tolerance for fail-operational designs |
Pinout & Package
TSSOP-16 package with full redundancy: two independent sensor dies sharing no internal power/ground paths; isolation resistance ≥4 MΩ between dice (VSS1–VSS2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require local 100 nF ceramic capacitors to ground for stable analog regulation |
| 2, 10 | VSS1 / VSS2 | Independent ground returns per die - mandatory separation prevents single-point failure propagation |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - enables dual-rail monitoring and supply fault discrimination |
| 4, 13 | Test11 / Test21 | Factory test pins - internally grounded in application mode; connect to PCB ground for EMC compliance |
| 5, 12 | Test22 / Test12 | Factory test pins - internally grounded in application mode; connect to PCB ground for EMC compliance |
| 6, 15 | OUT2 / OUT1 | Independent digital outputs per die - support cross-die comparison for fault detection in safety architectures |
| 7, 8, 14, 16 | N.C. | No-connect terminals - must be tied to ground per Melexis EMC recommendation |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous Bx, By, Bz measurement enables absolute linear position decoding without mechanical stops or multi-turn gears |
| Programmable Linear Transfer | 12–16 point user-defined lookup table - allows precise compensation of non-ideal magnet geometry or air gap variation |
| Dual-Die Redundancy | Independent signal chains with isolated VDD/VSS/VDEC - meets ASIL-D decomposition requirements when combined with external voter logic |
| SENT Secure Sensor Format | Includes CRC, error codes, and user-defined payload - enables diagnostic traceability and secure ECU communication |
| Broken-Wire Detection | Active monitoring of VDD/VSS continuity with <10 kΩ pull-down threshold - detects open-circuit faults before system failure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute linear position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90423GDC-ACA-430-RE | SOIC-8 single-die package; no hardware redundancy; lower pin count; 3000 pcs/reel | Lacks dual-die isolation and inter-die comparison capability - suitable for ASIL-B or non-safety-critical linear legacy use | Select when cost, board space, or safety integrity below ASIL-C is acceptable |
| MLX90423GGO-ACA-230-RE | Same TSSOP-16 dual-die package but configured for linear stray-field robust mode (–2xx), supporting both linear and 360° modes | Enables field-upgradeable 360° shaft sensing; includes enhanced stray field immunity algorithms not present in –430 variant | Select when future 360° capability or higher stray field margin (>5 mT) is required |
Compared with MLX90423GGO-ACA-430-RE, the SOIC-8 alternative reduces footprint and cost but sacrifices hardware redundancy, while the –230 variant adds magnetic flexibility and extended stray field resilience at the expense of fixed linear-legacy configuration.

FAQ
What output protocols does the MLX90423GGO-ACA-430-RE support?
The MLX90423GGO-ACA-430-RE supports three user-selectable output protocols: ratiometric analog (0–100% VDD), PWM (100–2000 Hz), and SENT per SAE J2716 APR2016. All are programmable via on-chip NVRAM and retain configuration across power cycles. The MLX90423GGO-ACA-430-RE defaults to SENT at power-on but can be reconfigured in-system using Melexis' PTC software and compatible programming interface.
Is the MLX90423GGO-ACA-430-RE pin-compatible with other MLX90423 variants?
No - the MLX90423GGO-ACA-430-RE uses the TSSOP-16 package with dual-die layout, while SOIC-8 variants (e.g., MLX90423GDC-ACA-430-RE) have different pin count, pin functions, and no redundancy. Pin mapping differs fundamentally: TSSOP-16 has separate VDD1/VDD2, VSS1/VSS2, and OUT1/OUT2 lines, whereas SOIC-8 consolidates these into single rails. The MLX90423GGO-ACA-430-RE requires dedicated PCB layout for its 16-pin dual-die architecture.
What is the functional safety classification of the MLX90423GGO-ACA-430-RE?
The MLX90423GGO-ACA-430-RE is certified as ISO 26262 SEooC with ASIL-C for SENT and PWM outputs and ASIL-B for analog output. Its dual-die TSSOP-16 implementation enables hardware-level fault detection, including inter-die comparison, broken-wire monitoring, and CRC-protected communication. The MLX90423GGO-ACA-430-RE safety manual (document MLX90423-SM-001) defines diagnostic coverage metrics and fault handling intervals such as DCT_dig = 20 ms.
Does the MLX90423GGO-ACA-430-RE support 360° angular sensing?
No - the MLX90423GGO-ACA-430-RE is factory-configured for linear legacy magnetic operation (–4xx option code) and does not support 360° trough-shaft mode. That capability is exclusive to –2xx variants (e.g., MLX90423GGO-ACA-230-RE). The MLX90423GGO-ACA-430-RE's internal firmware and magnetic configuration are locked to linear position decoding; attempting to repurpose it for rotary applications will result in invalid output data.
What is the maximum stray magnetic field immunity of the MLX90423GGO-ACA-430-RE?
The MLX90423GGO-ACA-430-RE provides stray field immunity up to 5 mT (4 kA/m) DC as specified in ISO 11452-8, applicable to linear legacy configurations. This immunity is achieved through Triaxis® Hall technology and on-chip differential signal processing. The MLX90423GGO-ACA-430-RE maintains full accuracy and functional safety compliance within this limit, making it suitable for placement near electric motors, solenoids, or high-current conductors in automotive chassis modules.
