Product details
Overview
MLX90365LGO-ACD-000-SP from Melexis is an AEC-Q100 qualified Triaxis® Hall-effect absolute position sensor IC in TSSOP-16 package, delivering 12-bit analog or PWM output with ±0.3° magnetic angle phase error (XY axis), 126 mT BZ sensitivity, and automotive-grade operation from −40 °C to +150 °C. It decodes rotary (0–360°) or linear displacement using orthogonal and parallel magnetic field components (BX, BY, BZ), enabling non-contacting potentiometer replacement in throttle and steering systems.
For engineers reviewing the MLX90365LGO-ACD-000-SP datasheet, pinout, applications, or equivalent options, key selection considerations include dual-die redundancy, programmable piece-wise-linear transfer characteristic, open/short diagnostics, thermal offset correction capability, and compliance with automotive EMC and safety requirements.
Technical Context
The MLX90365LGO-ACD-000-SP integrates a Triaxis® Hall front-end sensing all three magnetic flux components (BX, BY, BZ), a 16-bit RISC DSP for real-time arctangent computation, and dual-die architecture for functional safety. Its on-chip EEPROM stores 48-bit ID, calibration data, and user-programmable parameters including clamping thresholds, filter modes, and diagnostic settings.
It supports two output configurations: ratiometric analog (0–100% VDD) and programmable PWM (100–1000 Hz), both with 12-bit resolution and ≤±0.05%VDD ratiometry error over 4.5–5.5 V supply. The device implements active diagnostics including broken VDD/VSS detection and field strength monitoring, with dedicated diagnostic output levels defined per failure mode.

TSSOP-16 package with dual-die redundancy; RoHS compliant; exposed pad recommended for thermal and EMC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDIG1 | Digital supply for Die 1 - must be decoupled locally to minimize noise coupling into logic domain. |
| 2 | VSS1 | Digital ground for Die 1 - requires low-impedance connection to system ground plane. |
| 3 | VDD1 | Analog supply for Die 1 - separate from VDIG1 to isolate analog reference stability. |
| 4 | Test 01 | Factory test pin - not connected in end application; tie to VSS for EMC compliance. |
| 5 | Test 22 | Factory test pin - unused in production; connect to VSS to reduce EMI susceptibility. |
| 6 | OUT2 | PWM/analog output for Die 2 - enables cross-checking against OUT1 for safety-critical redundancy. |
| 7 | Not Used | No internal connection - must be tied to VSS per datasheet recommendation for optimal EMC. |
| 8 | VSS2 | Digital ground for Die 2 - independent return path prevents ground bounce between dies. |
| 9 | VDIG2 | Digital supply for Die 2 - decoupling capacitor required within 2 mm of pin. |
| 10 | VSS2 (Ground2) | Redundant digital ground - maintains isolation between die domains during fault conditions. |

The MLX90365LGO-ACD-000-SP supports configurable diagnostic thresholds and reporting modes via EEPROM programming.
Is the MLX90365LGO-ACD-000-SP pin-compatible with other MLX90365 variants?
Yes, all MLX90365 variants in TSSOP-16 package - including MLX90365LGO-ACD-000-SP, MLX90365KGO-ACD-000-RE, and MLX90365LGO-ACE-000-SP - share identical pinout, footprint, and electrical interface.
