Product details
Overview
MLX90365LDC-ACD-000-SP from Melexis is an AEC-Q100 qualified absolute rotary and linear position sensor IC based on Triaxis® Hall technology, delivering 12-bit analog or PWM output with 10-bit thermal accuracy, open/short diagnostics, and automotive-grade operation from −40 °C to +150 °C in SOIC-8 package. It decodes absolute angular position (0–360°) or linear displacement using orthogonal and parallel magnetic field components (BX, BY, BZ), enabling non-contacting potentiometer replacement in throttle, pedal, and steering applications.
For engineers reviewing the MLX90365LDC-ACD-000-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for automotive and industrial position sensing designs requiring ratiometric analog or programmable PWM output with on-chip diagnostics and thermal offset correction.
Technical Context
The MLX90365LDC-ACD-000-SP integrates a Triaxis® Hall front-end sensing all three magnetic flux components (BX, BY, BZ), a 16-bit RISC microcontroller running at 10 MHz (2.5 MIPS), 12-bit DAC, 12-bit PWM generator, and EEPROM-based programmability for transfer characteristic, output mode, and diagnostics. Its DSP performs real-time coordinate rotation (CoRDiC) to compute absolute angle from raw sine/cosine signals.
It supports two output modes-ratiometric analog (0–100% VDD) and programmable PWM (100–1000 Hz)-with configurable filter stages (0–2), clamping levels, and diagnostic reporting via dedicated output states. The SOIC-8 variant uses a single die with integrated 2.5 V regulator, over-voltage protection up to +24 V, and under-voltage detection at 3.8–4.2 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90364LDC-ACD-000-SP | Single-axis Hall sensor with 10-bit output; lacks Triaxis® BZ sensing and CoRDiC computation. | Suitable only for simple rotary or linear motion where Z-field independence is not required. | Select when cost sensitivity outweighs need for 3D field immunity and absolute angle reconstruction. |
| TLE5012BE1000 | Infineon 3D Hall sensor with 14-bit resolution and SPI interface; no native PWM output or EEPROM programmability. | Requires external MCU for transfer function mapping and diagnostics handling. | Choose for high-resolution SPI-based systems needing extended diagnostics but accepting higher BOM complexity. |
Compared with MLX90365LDC-ACD-000-SP, MLX90364LDC-ACD-000-SP reduces functionality to single-axis sensing and removes thermal offset correction, while TLE5012BE1000 adds resolution and SPI flexibility but shifts calibration and diagnostics burden to the host controller-making MLX90365LDC-ACD-000-SP optimal for self-contained, drop-in analog/PWM replacements in automotive subsystems.

FAQ
What is the operating temperature range of the MLX90365LDC-ACD-000-SP?
The MLX90365LDC-ACD-000-SP operates from −40 °C to +150 °C and is AEC-Q100 qualified for Grade 0 automotive applications. This rating covers under-hood locations such as throttle bodies, suspension modules, and transmission housings where ambient temperatures exceed 125 °C during peak load conditions. The device maintains 10-bit thermal accuracy across this full range due to on-chip offset correction algorithms.
Does the MLX90365LDC-ACD-000-SP support both analog and PWM outputs simultaneously?
No, the MLX90365LDC-ACD-000-SP supports only one output mode at a time-either ratiometric analog (0–100% VDD) or programmable PWM (100–1000 Hz)-selected during factory or end-user programming. The output stage is configured via EEPROM bits; switching modes requires reprogramming the device using Melexis' PTC software and compatible programmer hardware. Both modes share the same OUT pin (Pin 5).
How is the MLX90365LDC-ACD-000-SP calibrated for specific magnetic assemblies?
The MLX90365LDC-ACD-000-SP supports end-user programmable transfer characteristics with up to 17 calibration points stored in EEPROM. Using Melexis' PTC GUI and a compatible programmer, users perform multi-point angular or linear sweeps to capture raw sensor data, then generate and flash a piecewise-linear mapping that compensates for mechanical tolerances, magnet non-uniformity, and air-gap variation-without modifying hardware or firmware.
What diagnostic capabilities does the MLX90365LDC-ACD-000-SP provide?
The MLX90365LDC-ACD-000-SP provides open-circuit, short-circuit, broken VDD/VSS, and magnetic field strength diagnostics. These are reported through defined output state transitions (e.g., clamped low/high, PWM duty cycle deviation) rather than separate pins. Diagnostic behavior-including activation level and response mode-is fully programmable via EEPROM settings, enabling integration into ASIL-B safety architectures without external monitoring ICs.
Is the MLX90365LDC-ACD-000-SP pin-compatible with other MLX90365 variants?
Yes, all SOIC-8 packaged MLX90365 variants-including MLX90365LDC-ACD-000-SP, MLX90365KDC-ACD-000-SP, and MLX90365EDC-ACD-000-SP-share identical pinout, footprint, and electrical interface. Differences are limited to temperature grade (L = −40 °C to +150 °C), option code (ACD = standard version), and packing form (SP = sample reel). No PCB layout change is needed when upgrading from K- or E-grade versions.
