Product details
Overview
MLX90365KDC-ACD-000-SP from Melexis is an AEC-Q100 qualified Triaxis® Hall-effect absolute position sensor IC in SOIC-8 package, delivering 12-bit analog or PWM output with programmable transfer characteristics, thermal offset correction, and open/short diagnostics for rotary and linear position sensing. It operates from −40 °C to +125 °C and supports ratiometric analog output compatible with potentiometer interfaces.
For engineers reviewing the MLX90365KDC-ACD-000-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin functions, automotive-grade accuracy specs (±0.3° angular error at 25 °C), real-world application cards, and two confirmed alternative parts with documented functional differences.
Technical Context
The MLX90365KDC-ACD-000-SP integrates a Triaxis® Hall front-end sensing BX, BY, and BZ magnetic field components, enabling absolute angle computation via on-chip CoRDiC-based DSP. Its 16-bit RISC microcontroller executes firmware for multi-point piecewise-linear transfer function programming and real-time thermal offset correction.
It features dual-output capability-programmable ratiometric analog (0–100% VDD) or 100–1000 Hz PWM-with independent diagnostic reporting via dedicated output saturation levels and clamping thresholds. All diagnostics-including broken VDD/VSS detection and field strength monitoring-are configurable via EEPROM and executed autonomously without host intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365KGO-ACD-000-RE | Dual-die TSSOP-16 package with full hardware redundancy; higher supply current (2×), isolated diagnostics between dice | Required for ASIL-D systems where fault tolerance mandates physical die separation and independent signal paths | Select when functional safety architecture requires hardware-level redundancy beyond single-die diagnostics |
| MLX90365LDC-ACE-000-SP | L-grade (−40 °C to +150 °C) with enhanced thermal offset correction algorithm; same SOIC-8 footprint | Suitable for high-temperature zones (e.g., near turbochargers or exhaust manifolds) where K-grade thermal margin is insufficient | Choose for under-hood locations exceeding +125 °C ambient, retaining identical PCB layout and calibration workflow |
Compared with MLX90365KDC-ACD-000-SP, the KGO-ACD variant adds physical redundancy for ASIL-D compliance but doubles board area and power draw, while the LDC-ACE variant extends temperature range to +150 °C with improved thermal drift compensation-both retain identical programming interface and EEPROM structure.

FAQ
What is the operating temperature range of the MLX90365KDC-ACD-000-SP?
The MLX90365KDC-ACD-000-SP is rated for −40 °C to +125 °C ambient operation (K-grade), validated per AEC-Q100 Grade 0 requirements. This range covers most under-hood automotive locations, including engine control modules and transmission control units, with full functionality maintained across the entire span including startup at extreme cold and sustained operation at peak heat.
Does the MLX90365KDC-ACD-000-SP support both analog and PWM output modes?
Yes, the MLX90365KDC-ACD-000-SP supports both ratiometric analog voltage output (0–100% VDD) and programmable PWM output (100–1000 Hz). The output mode is selected via EEPROM configuration during programming; no hardware change is required. Both modes deliver 12-bit resolution and share the same OUT pin, with identical diagnostic coverage.
How is thermal offset corrected in the MLX90365KDC-ACD-000-SP?
The MLX90365KDC-ACD-000-SP applies real-time thermal offset correction in firmware using on-chip temperature measurements and pre-stored coefficients. This correction reduces angular zero-point drift to ±0.3° over −40 °C to +125 °C, directly improving accuracy in throttle and pedal applications where temperature gradients are severe and uncontrolled.
What diagnostics does the MLX90365KDC-ACD-000-SP provide?
The MLX90365KDC-ACD-000-SP provides autonomous diagnostics including open/short detection on the OUT pin, broken VDD and VSS supply monitoring, magnetic field strength validation, and PWM-specific jitter and duty cycle deviation alerts. All diagnostics generate defined saturation or clamping output states readable by the host ECU without additional circuitry.
Is the MLX90365KDC-ACD-000-SP pin-compatible with other MLX90365 variants?
Yes, the MLX90365KDC-ACD-000-SP shares identical SOIC-8 pinout and electrical behavior with all other DC-package MLX90365 variants (e.g., EDC, LDC). Pin functions, supply requirements, and output drive strength are fully consistent, enabling drop-in replacement within the same temperature grade and option code family.
