Product details
Overview
MLX90365EDC-ABB-000-RE 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, ±70 mT XY magnetic sensitivity, and automotive-grade operation from −40 °C to +150 °C. It decodes rotary (0–360°) or linear displacement using orthogonal and parallel flux components (BX, BY, BZ), enabling non-contacting potentiometer replacement in throttle and steering systems.
For engineers reviewing the MLX90365EDC-ABB-000-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, automotive-specific features, four concrete application implementations, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MLX90365EDC-ABB-000-RE integrates a Triaxis® Hall front-end sensing all three magnetic field components (BX, BY, BZ) via on-die IMC structures, feeding a 16-bit RISC DSP that computes angular or linear position using CoRDiC-based rectangular-to-polar transformation. Its dual-path architecture supports simultaneous analog ratiometric output (0–100% VDD) and programmable PWM (100–1000 Hz) with independent filter settings (Filter=0–2).
On-chip diagnostics include open/short detection on OUT, broken VDD/VSS monitoring, thermal offset correction (enabled in ABB variant), and EEPROM-stored 48-bit ID. The SOIC-8 package houses a single die with integrated 2.5 V regulator, 12-bit DAC, and push-pull or open-drain output stage configurable via end-user programming of CLAMP_HIGH/LOW, MAPXYZ, and DIAG mode.

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-ABD-000-RE | TSSOP-16 dual-die package with full hardware redundancy; higher supply current (2× IDD); isolated inter-die diagnostics | Required for ASIL-D systems needing fault-tolerant position feedback; not pin-compatible with SOIC-8 | Select when functional safety mandates hardware redundancy; requires PCB redesign and higher power budget |
| MLX90367EDC-ABB-000-RE | Same SOIC-8 package and pinout; adds SPI interface and enhanced diagnostics; 14-bit resolution; identical magnetic specs | Used where host MCU requires digital position data or advanced diagnostic logging beyond analog/PWM | Choose for new designs needing firmware-updatable calibration or integration with CAN FD gateways without ADC overhead |
Compared with MLX90365EDC-ABB-000-RE, the GO-ABD variant provides hardware redundancy at the cost of larger footprint and doubled current draw, while the MLX90367 offers digital communication and higher resolution without changing board layout-making it ideal for scalable platform designs requiring both analog legacy support and future digital upgrade paths.

FAQ
What is the operating temperature range of the MLX90365EDC-ABB-000-RE?
The MLX90365EDC-ABB-000-RE operates from −40 °C to +150 °C and is AEC-Q100 qualified for Grade 0 automotive applications. This range covers under-hood environments such as throttle bodies and suspension modules, where sustained high-temperature exposure is typical. Its thermal offset correction ensures angular accuracy remains within ±0.3° across the full span, eliminating need for external temperature compensation in the MLX90365EDC-ABB-000-RE design.
Does the MLX90365EDC-ABB-000-RE support both analog and PWM outputs simultaneously?
No, the MLX90365EDC-ABB-000-RE supports only one output mode at a time-either ratiometric analog (0–100% VDD) or PWM (100–1000 Hz)-configured via EEPROM programming during end-of-line calibration. The output stage is shared, so concurrent use is not possible. This single-mode constraint simplifies EMC filtering and reduces output-stage complexity in the MLX90365EDC-ABB-000-RE, aligning with its target in cost-sensitive, high-volume automotive sensors.
What magnetic field strength is required for reliable operation of the MLX90365EDC-ABB-000-RE?
The MLX90365EDC-ABB-000-RE requires ≥70 mT in XY axes or ≥126 mT in BZ axis for full-scale operation, with optimal signal-to-noise ratio above 20 mT magnetic norm. Below 20 mT, linearity degrades due to reduced SNR; above 70 mT, IMC saturation increases intrinsic error. Typical designs use NdFeB magnets (Br ≈ 1.2 T) at 2–4 mm air gap, ensuring robust field delivery across temperature and aging in the MLX90365EDC-ABB-000-RE application.
How is diagnostics implemented in the MLX90365EDC-ABB-000-RE?
The MLX90365EDC-ABB-000-RE integrates open/short detection on the OUT pin, broken VDD/VSS monitoring, over-voltage protection (up to +24 V), and under-voltage lockout (MT4V threshold at 4.0 V). Diagnostic status is reported via dedicated output levels (e.g., Dsat_lo/Dsat_hi) or clamped states, configurable through DIAG mode bits. These on-chip diagnostics eliminate external comparators in the MLX90365EDC-ABB-000-RE, reducing BOM count and PCB area while meeting ASIL-B fault coverage targets.
Is the MLX90365EDC-ABB-000-RE pin-compatible with other MLX90365 variants?
Yes, all SOIC-8 variants-including MLX90365EDC-ABB-000-RE, MLX90365KDC-ACD-000-RE, and MLX90365LDC-ACE-000-RE-share identical pinout, footprint, and electrical interface. Differences lie in temperature grade (E/K/L), EEPROM programming (ABB vs ACE thermal correction), and option code (ABB = standard, ACE = enhanced thermal offset). This allows drop-in replacement during qualification or thermal derating without layout changes for the MLX90365EDC-ABB-000-RE.
