Product details
Overview
MLX90340LGO-AAA-000-SP from Melexis is a dual-die, fully redundant Triaxis® Hall-effect IC for absolute rotary and linear position sensing, delivering 12-bit analog or PWM output with ±0.5° angular accuracy over -40°C to 150°C, programmable 4- or 17-point transfer characteristics, and integrated DSP-based magnetic angle computation from Bx/By/Bz vector components.
For engineers reviewing the MLX90340LGO-AAA-000-SP datasheet, pinout, applications, or equivalent options, this device supports heavy-duty industrial motor feedback, non-contacting potentiometer replacement, and safety-critical position sensing where redundancy, thermal stability, and field-programmable transfer curves are required.
Technical Context
The MLX90340LGO-AAA-000-SP implements dual independent sensor dies in one TSSOP-16 package, each with full signal chain (Triaxis® front-end, 15-bit ADC, 16-bit RISC microcontroller, ROM firmware, EEPROM with Hamming ECC), enabling true hardware redundancy for ASIL-B/C applications. Each die independently computes angle via CoRDiC-based arctan(Bj/Bi) from orthogonal flux components.
It supports ratiometric analog output (0–VDD, 12-bit DAC) or PWM output (12-bit resolution, 100 kHz typical frequency), both fully programmable for offset, gain, clamping, and multi-point linearity correction - with calibration data stored in error-corrected NVRAM accessible via supply/output pins only, no dedicated programming interface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit analog or PWM output - enables 0.088° angular step resolution over 360° range. |
| Angular Accuracy | ±0.5° over full temperature range (-40°C to +150°C) - ensures stable position reporting without external compensation. |
| Operating Temp | -40°C to +150°C - qualified for under-hood automotive and industrial motor control environments. |
| Transfer Curve | Programmable 4-point LNR or 17-point PWL mapping - allows precise matching to mechanical stroke or rotary cam profiles. |
| Redundancy | Dual independent dies in single TSSOP-16 package - supports cross-checking for functional safety compliance (e.g., ISO 26262). |
| Supply Voltage | 4.5 V to 24 V - compatible with 12 V and 24 V vehicle/bus systems without external regulators. |
| Magnetic Input | Sensitive to Bx, By, Bz vector components - enables absolute angle calculation from rotating or linearly moving magnets. |
Pinout & Package
TSSOP-16 package with dual-die architecture: two independent sensor channels (Die 1 and Die 2), each with dedicated supply (VDD_1/VDD_2), ground (VSS_1/VSS_2), regulator (VDIG1/VDIG2), and output (OUT1/OUT2) pins; test and unused pins must be grounded for EMC compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDIG1 / VDIG2 | Internal 3.3 V regulator outputs - power internal digital blocks; require 100 nF decoupling per pin. |
| 2, 10 | VSS_1 / VSS_2 | Dedicated ground returns for each die - mandatory separation prevents crosstalk between redundant paths. |
| 3, 11 | VDD_1 / VDD_2 | Primary supply inputs (4.5–24 V) for each die - support independent power domain monitoring. |
| 6, 15 | OUT2 / OUT1 | Independent analog/PWM outputs - enable real-time comparison or voting logic in safety architectures. |
| 4, 5, 8, 12, 13, 14, 16 | Test / Not Used | No functional connection - must be tied to ground per datasheet to minimize EMI susceptibility. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die redundancy | Two physically independent sensor dies in one TSSOP-16 package enable hardware-level fault detection without external circuitry. |
| Triaxis® vector sensing | Simultaneous measurement of Bx, By, Bz enables robust absolute angle calculation immune to magnet misalignment or air-gap variation. |
| Field-programmable transfer curve | 4- or 17-point piecewise-linear calibration stored in ECC-protected NVRAM - eliminates need for post-assembly trimming or external lookup tables. |
| Ratiometric analog + PWM dual output | Single device supports both analog voltage (0–VDD) and PWM (100 kHz) outputs - simplifies system integration across legacy and modern controller interfaces. |
| No dedicated programming pins | Full configuration via VDD/OUT pins only - reduces PCB routing complexity and enables in-system calibration during production or field service. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365GO-ABA-000-SP | Single-die TSSOP-16 with extended 360° analog output, same Triaxis® core but no dual-die redundancy. | Lacks hardware-level fault detection; suitable for non-safety-critical industrial encoders. | Select when cost and board space constrain redundancy requirements but Triaxis® vector sensing is still needed. |
| AS5055A-DSOM | 14-bit SPI-output magnetic encoder IC in QFN-16; no analog/PWM output, no programmable transfer curve. | Requires external MCU for interpolation and diagnostics; limited to SPI-based systems. | Choose for high-resolution digital-only interfaces where firmware-controlled calibration is acceptable. |
Compared with MLX90340LGO-AAA-000-SP, the MLX90365GO-ABA-000-SP offers identical package and magnetic performance but omits dual-die redundancy, while the AS5055A-DSOM provides higher resolution via SPI but removes analog/PWM flexibility and field-programmable linearity - making MLX90340LGO-AAA-000-SP uniquely suited for safety-aware analog/PWM systems needing on-chip redundancy and calibration.

FAQ
What is the operating temperature range of the MLX90340LGO-AAA-000-SP?
The MLX90340LGO-AAA-000-SP operates from -40°C to +150°C, qualified for under-hood automotive and industrial environments. This rating applies to the full dual-die TSSOP-16 variant and is verified per AEC-Q100 Grade 0 stress testing. The device maintains ±0.5° angular accuracy across this entire range without external compensation circuits.
Does the MLX90340LGO-AAA-000-SP support both analog and PWM output simultaneously?
No - the MLX90340LGO-AAA-000-SP supports either ratiometric analog output (0–VDD) or PWM output (12-bit resolution, ~100 kHz), selected during programming. Both modes are available per die, but each output pin (OUT1/OUT2) delivers only one signal type at a time. The selection is stored in EEPROM and persists through power cycles.
How is programming performed on the MLX90340LGO-AAA-000-SP without dedicated pins?
Programming of the MLX90340LGO-AAA-000-SP uses only VDD and OUT pins - no additional programming interface is required. Configuration (transfer curve, output mode, diagnostics) is executed via voltage pulses on VDD while monitoring OUT response, using Melexis' PTC-04 programmer and DB90316 software. All parameters are stored in ECC-protected NVRAM inside the MLX90340LGO-AAA-000-SP.
What does "dual-die" mean for the MLX90340LGO-AAA-000-SP in TSSOP-16?
"Dual-die" means the MLX90340LGO-AAA-000-SP integrates two fully independent Triaxis® sensor ICs - each with its own Hall front-end, ADC, DSP, EEPROM, and output stage - within a single TSSOP-16 package. Die 1 and Die 2 operate autonomously, enabling hardware-level redundancy, cross-checking, and fault detection required for ASIL-B/C systems.
Can the MLX90340LGO-AAA-000-SP be used with standard SOIC-8 footprints?
No - the MLX90340LGO-AAA-000-SP uses a TSSOP-16 package (4.4 mm × 5.0 mm, 0.65 mm pitch), not SOIC-8. The "GO" package code explicitly denotes TSSOP-16 dual-die construction. SOIC-8 variants exist (e.g., MLX90340LDC-AAA-000-SP) but are single-die and lack redundancy. PCB layout must match TSSOP-16 dimensions and pinout for MLX90340LGO-AAA-000-SP.
