Product details
Overview
MLX90365EDC-ACD-000-RE from Melexis is an AEC-Q100 qualified absolute rotary and linear position sensor IC using Triaxis® Hall technology in SOIC-8 package. It delivers 12-bit analog or PWM output with ratiometric accuracy, 10-bit thermal accuracy, open/short diagnostics, and operates across −40 °C to +85 °C. It enables non-contacting potentiometer replacement in automotive pedal and throttle position sensing.
For engineers reviewing the MLX90365EDC-ACD-000-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its programmable multi-point transfer characteristic, dual-output mode flexibility (analog/PWM), integrated diagnostics, thermal offset correction capability, and SOIC-8 automotive-grade packaging.
Technical Context
The MLX90365EDC-ACD-000-RE integrates a Triaxis® Hall front-end sensing all three magnetic field components (BX, BY, BZ) to compute absolute angular or linear position via on-chip DSP and CoRDiC-based rectangular-to-polar conversion. Its 16-bit RISC microcontroller executes firmware for real-time signal processing, EEPROM-based calibration, and diagnostics.
It supports end-user programming of output transfer characteristics (4- or 17-point piecewise-linear), clamping thresholds, filter modes, diagnostic sensitivity, and magnetic mapping parameters (MAPXYZ, k factor). Output stage options include ratiometric analog (0–100% VDD) or programmable-frequency PWM (100–1000 Hz) with ±0.003% DC jitter at 100 Hz.

FAQ
What is the operating temperature range of the MLX90365EDC-ACD-000-RE?
The MLX90365EDC-ACD-000-RE is rated for operation from −40 °C to +85 °C (E-grade), validated per AEC-Q100 Rev G. This range covers passenger cabin and moderate under-hood locations such as accelerator pedal modules and HVAC actuators. Thermal offset correction and diagnostics remain fully functional across this span, with angular accuracy maintained within ±0.3° for rotary applications.
Does the MLX90365EDC-ACD-000-RE support both analog and PWM outputs simultaneously?
No, the MLX90365EDC-ACD-000-RE supports only one active output mode at a time-either ratiometric analog or PWM-selected during end-of-line programming. The OUT pin delivers either a 0–100% VDD analog voltage or a 100–1000 Hz PWM signal with 12-bit resolution. Switching between modes requires reprogramming the device's EEPROM configuration; concurrent dual-output operation is not supported.
How is magnetic field immunity achieved in the MLX90365EDC-ACD-000-RE?
The MLX90365EDC-ACD-000-RE achieves field immunity through Triaxis® Hall sensing, which measures BX, BY, and BZ orthogonally and computes position via on-chip DSP-rejecting common-mode interference. Its integrated magneto-concentrator (IMC®) enhances sensitivity while built-in diagnostics detect abnormal field strength. The device tolerates stray fields up to ±1 T and maintains accuracy even with axial misalignment, eliminating need for external shielding in most automotive mounting configurations.
Can the MLX90365EDC-ACD-000-RE be programmed in-system after soldering?
Yes, the MLX90365EDC-ACD-000-RE supports in-system programming via its I²C-compatible serial interface using the Melexis PTCLIB toolkit and compatible programmers (e.g., Melexis EVK or third-party tools with PTCLIB support). All end-user programmable items-including output mode, transfer curve points, clamping thresholds, and diagnostic settings-can be configured post-soldering without removing the MLX90365EDC-ACD-000-RE from the PCB.
What diagnostic functions are implemented in the MLX90365EDC-ACD-000-RE?
The MLX90365EDC-ACD-000-RE implements open-circuit, short-circuit, over-voltage (up to +24 V), under-voltage (MT4V detection), broken-track (VSS/VDD), and field-strength diagnostics. Diagnostic status is reported via dedicated flags in the output signal or via the diagnostic pin (configurable). These features enable ASIL-B–compliant system monitoring and reduce software validation effort for ISO 26262 applications involving the MLX90365EDC-ACD-000-RE.
