Product details
Overview
MLX90423GGO-ACA-230-SP from Melexis is a Triaxis® Hall-based monolithic magnetic position processor IC for absolute linear position sensing with stray field immunity up to 5 mT. It delivers SENT (SAE J2716 APR2016), PWM, or ratiometric analog output, supports ASIL-C functional safety for SENT/PWM modes, and operates from −40°C to +160°C in automotive throttle and pedal position systems.
For engineers reviewing the MLX90423GGO-ACA-230-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its TSSOP-16 dual-die redundant architecture, SENT protocol compliance, 360° trough-shaft programmability, ISO 26262 SEooC certification, and stray-field robust linear measurement range.
Technical Context
The MLX90423GGO-ACA-230-SP implements full redundancy via two independent dies in a single TSSOP-16 package, each with dedicated supply (VDD1/VDD2), ground (VSS1/VSS2), decoupling (VDEC1/VDEC2), and output (OUT1/OUT2) pins. Its Triaxis® front end measures Bx, By, and Bz components to compute absolute angle or linear position without mechanical contact.
It integrates on-chip DSP for LNR (linearization), configurable FIR filtering, programmable diagnostics (DCT_ana = 10.64–12.4 ms), and SENT frame generation with CRC and error codes. The -230 option configures it for linear stray-field-robust operation with factory-programmed SENT output and 12–16-point transfer characteristic calibration.

Pinout & Package
TSSOP-16 package with full redundancy: two independent sensor dies sharing no internal power/ground paths; isolation resistance >4 MΩ between VSS1–VSS2 confirms die-level independence for fault-tolerant designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDEC1 / VDEC2 | Decoupling pin (die 1 / die 2) | Requires local 100 nF ceramic capacitor to stabilize internal analog regulator per die |
| VSS1 / VSS2 | Ground (die 1 / die 2) | Independent ground returns - must be routed separately to avoid coupling faults |
| VDD1 / VDD2 | Supply (die 1 / die 2) | Separate supply inputs - enables independent power domain monitoring and fault detection |
| OUT1 / OUT2 | Output (die 1 / die 2) | Dual SENT/PWM outputs - supports cross-checking or voting logic in ASIL-C systems |
| Test11 / Test12 / Test21 / Test22 | Factory test pins | Internally grounded in application mode; tie to PCB ground for EMC compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90422GGO-ACA-230-SP | Single-die variant in same TSSOP-16 package; lacks dual-die isolation and ASIL-C certification | Suitable for ASIL-B or non-safety-critical linear position tasks; no hardware redundancy | Select when cost sensitivity outweighs ASIL-C requirement and system-level redundancy is implemented externally |
| AMS AS5600-DSW | Single-die I²C angle sensor; no SENT/PWM output; max operating temp +85°C; no AEC-Q100 or ISO 26262 support | Targeted at consumer/industrial encoders; not qualified for automotive powertrain or chassis applications | Choose only for non-automotive, low-temp, I²C-based designs where functional safety is not mandated |
Compared with MLX90423GGO-ACA-230-SP, the MLX90422GGO-ACA-230-SP reduces cost and complexity but sacrifices hardware-level fault tolerance, while the AMS AS5600-DSW offers simpler digital interfacing yet lacks automotive qualification, stray-field immunity, and safety certification required for throttle or pedal use cases.

FAQ
What output protocols does the MLX90423GGO-ACA-230-SP support?
The MLX90423GGO-ACA-230-SP supports SENT (SAE J2716 APR2016), PWM, and ratiometric analog outputs. Factory-programmed for SENT in the -230 option, it can be reconfigured in-system to PWM or analog via end-user programming. Each output mode includes built-in diagnostics and error reporting, and SENT frames embed CRC, status flags, and user-defined data per the Secure Sensor format.
How does the dual-die architecture of the MLX90423GGO-ACA-230-SP enable ASIL-C compliance?
The MLX90423GGO-ACA-230-SP achieves ASIL-C through physically isolated dual dies in the TSSOP-16 package - with separate VDD1/VDD2, VSS1/VSS2, VDEC1/VDEC2, and OUT1/OUT2 pins - enabling independent fault detection, cross-checking, and fail-safe state activation. Its ISO 26262 SEooC documentation covers diagnostic coverage, fault handling time intervals (e.g., DCT_dig = 20 ms), and hardware fault tolerance metrics validated per ASIL-C requirements.
What is the meaning of the "-230" option code in MLX90423GGO-ACA-230-SP?
The "-230" option code in MLX90423GGO-ACA-230-SP specifies three configuration layers: "2" = linear stray-field-robust magnetic configuration (supports 360° trough-shaft decoding), "3" = pre-programmed SENT output mode (reconfigurable to PWM/analog), and "0" = standard straight leads. This factory setting ensures immediate deployment in automotive throttle and pedal applications without initial programming.
Can the MLX90423GGO-ACA-230-SP operate directly from a 12 V battery supply?
Yes, the MLX90423GGO-ACA-230-SP supports battery-supply operation from 6 V to 18 V in PWM and SENT modes, eliminating the need for an external voltage regulator. Its internal regulators generate stable VDEC (3.2–3.4 V) and VDIG rails, and the device includes brown-out detection (VDDUVL = 3.75–4.05 V) and PTC entry thresholds (VPROV0 = 5.85–6.25 V) to manage undervoltage and overvoltage conditions safely.
What magnetic field immunity does the MLX90423GGO-ACA-230-SP provide, and how is it verified?
The MLX90423GGO-ACA-230-SP provides stray magnetic field immunity up to 5 mT (4 kA/m) as validated per ISO 11452-8. This is achieved via Triaxis® technology and on-chip differential signal processing that rejects common-mode field interference. The -230 option is factory calibrated for linear operation under such fields, ensuring ±0.5° accuracy remains intact even when exposed to EMI from adjacent solenoids or motors.
