Overview
MLX90365LGO-ACE-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 thermal offset correction. It operates across −40 °C to +150 °C in TSSOP-16 package and is used in automotive pedal, steering wheel, and throttle position sensing.
For engineers reviewing the MLX90365LGO-ACE-000-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, pin-level circuit roles, real-world application mapping, and validated alternative options for automotive-grade non-contact position sensing designs.
Technical Context
The MLX90365LGO-ACE-000-SP integrates a Triaxis® Hall front-end sensing all three magnetic field components (BX, BY, BZ), enabling absolute angular or linear position decoding via on-chip DSP and CoRDiC-based rectangular-to-polar conversion. Its dual-die TSSOP-16 architecture supports full redundancy for ASIL-B functional safety compliance.
It features programmable multi-point piecewise-linear transfer characteristics, selectable ratiometric analog or PWM output modes, and embedded diagnostics including open/short detection, over-voltage protection, under-voltage detection, and thermal offset correction-enabled by the ACE option code per ordering information.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365LDC-ACD-000-RE | SOIC-8 single-die variant; no thermal offset correction (ACD vs ACE); lower pin count, no redundancy | Suitable for cost-sensitive non-safety-critical linear/rotary sensing where ambient temperature stays <125 °C | Select when footprint size and BOM cost outweigh redundancy and extended thermal compensation needs |
| MLX90375LGO-ABE-000-RE | Next-generation Triaxis® IC with 14-bit resolution, enhanced EMC immunity, and updated EEPROM programming interface | Designed for new designs targeting ASIL-C; not drop-in compatible due to revised pinout and firmware protocol | Choose for future-proofing and higher accuracy; requires PCB and firmware redesign versus MLX90365LGO-ACE-000-SP |
Compared with MLX90365LGO-ACE-000-SP, the SOIC-8 ACD variant trades thermal compensation and redundancy for smaller size and lower cost, while the MLX90375 offers higher resolution and ASIL-C readiness at the expense of compatibility-making MLX90365LGO-ACE-000-SP the optimal choice for ASIL-B-compliant, thermally demanding automotive position sensing with proven field reliability.

FAQ
What is the key functional difference between MLX90365LGO-ACE-000-SP and other MLX90365 variants?
The MLX90365LGO-ACE-000-SP uniquely combines the TSSOP-16 dual-die package with the ACE option code, enabling both full hardware redundancy and active thermal offset correction. This distinguishes it from SOIC-8 variants (no redundancy) and ACD-coded parts (no thermal correction), making MLX90365LGO-ACE-000-SP the only variant qualified for ASIL-B applications requiring both fault tolerance and high-temperature accuracy.
Does MLX90365LGO-ACE-000-SP support both analog and PWM outputs simultaneously?
No-MLX90365LGO-ACE-000-SP supports either ratiometric analog or PWM output mode, selected during end-user programming via the OUT mode parameter. The device does not generate both outputs concurrently; OUT1 and OUT2 deliver identical signal types from each die, enabling redundant readout but not mixed-mode operation.
How is thermal offset correction implemented in MLX90365LGO-ACE-000-SP?
Thermal offset correction in MLX90365LGO-ACE-000-SP is performed in real time by the on-chip DSP using factory-trimmed coefficients stored in EEPROM. It compensates for temperature-induced zero-point drift in the Triaxis® front-end, reducing angular error to ±0.3° over −40 °C to +150 °C-confirmed in datasheet section 14.2.7 and accuracy table 9.1.
What are the mandatory PCB layout requirements for MLX90365LGO-ACE-000-SP?
Per datasheet section 16.2 and pinout table, all unused pins (Pins 7, 13) and test pins (Pins 4, 5, 11, 12, 15, 16) must be connected to ground to ensure EMC compliance and diagnostic stability. Additionally, separate VDD1/VSS1 and VDD2/VSS2 power domains require independent decoupling capacitors placed within 2 mm of respective pins.
Is MLX90365LGO-ACE-000-SP pin-compatible with earlier MLX90365 revisions?
Yes-MLX90365LGO-ACE-000-SP maintains identical TSSOP-16 pinout, electrical behavior, and programming interface with all prior GO-package MLX90365 versions (e.g., MLX90365LGO-ACD-000-RE). The ACE option adds functionality without altering physical or logical compatibility, allowing seamless upgrade in existing designs requiring enhanced thermal performance.
