Product details
Overview
MLX90365LDC-ABD-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 and steering systems.
For engineers reviewing the MLX90365LDC-ABD-000-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 package mapping, programmable transfer characteristic details, diagnostic behavior, and validated alternative options for automotive position sensing designs.
Technical Context
The MLX90365LDC-ABD-000-SP integrates a Triaxis® Hall front-end sensing all three magnetic flux components (BX, BY, BZ), a 16-bit RISC DSP with 2.5 MIPS, 128 B EEPROM for end-user programming, and dual-output stage supporting ratiometric analog (0–100% VDD) or PWM (100–1000 Hz). Its on-chip CoRDiC engine computes angular position from sine/cosine raw signals with 15-bit ADC resolution.
It features programmable diagnostics including open/short detection, broken VDD/VSS monitoring, thermal offset correction, and configurable FIR filtering (Filter=0–2). The device supports multi-point piecewise-linear transfer characteristic programming and includes 48-bit unique ID storage in EEPROM for traceability.

| 2 | Test 0 | Factory test pin; not used in application; requires grounding for EMC compliance |
| 3 | Test 2 | Factory test pin; not used in application; requires grounding for EMC compliance |
| 4 | Not Used | No internal connection; must be tied to ground to minimize noise coupling |
| 5 | OUT | Configurable output: ratiometric analog voltage (0–VDD) or PWM signal (100–1000 Hz) |
| 6 | Test 1 | Factory test pin; not used in application; requires grounding for EMC compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365LGO-ACD-000-RE | Dual-die TSSOP-16 variant with full hardware redundancy; higher supply current (2×); isolated diagnostics between dice | Required for ASIL-D systems needing fault-tolerant architecture; not pin-compatible with SOIC-8 MLX90365LDC-ABD-000-SP | Select when functional safety integrity exceeds ASIL-B or dual-channel voting is mandated by OEM specification |
| MLX90364LDC-ABD-000-SP | Legacy single-axis version; no BZ sensing; 10-bit resolution; no thermal offset correction; same SOIC-8 footprint | Limited to 2D rotary applications (e.g., simple knob controls); lacks Z-axis capability for 3D motion or tilt compensation | Consider only for cost-sensitive, non-automotive designs where Triaxis® 3D capability is unnecessary |
Compared with MLX90365LDC-ABD-000-SP, the MLX90365LGO-ACD-000-RE adds hardware redundancy at the cost of PCB area and power, while the MLX90364LDC-ABD-000-SP sacrifices Triaxis® 3D sensing and thermal accuracy for lower bill-of-materials-neither is pin-compatible, requiring layout revision.

FAQ
What is the operating temperature range of the MLX90365LDC-ABD-000-SP?
The MLX90365LDC-ABD-000-SP 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 engine control modules and transmission control units where thermal stability is critical. The device includes on-chip thermal offset correction to maintain angular accuracy across the full span.
Does the MLX90365LDC-ABD-000-SP support both analog and PWM outputs simultaneously?
No, the MLX90365LDC-ABD-000-SP supports only one output mode at a time-either ratiometric analog voltage (0–VDD) or PWM (100–1000 Hz)-configured via EEPROM programming during end-of-line calibration. The OUT pin cannot deliver both signals concurrently; switching requires reprogramming and power cycle.
Is the MLX90365LDC-ABD-000-SP pin-compatible with other MLX90365 variants in SOIC-8 package?
Yes, all MLX90365 variants in SOIC-8 package-including MLX90365LDC-ACD-000-RE and MLX90365LDC-ACE-000-SP-share identical pinout, footprint, and electrical interface. The MLX90365LDC-ABD-000-SP differs only in factory programming (e.g., default output mode, clamping levels) and is not recommended for new designs per Melexis documentation.
How does the MLX90365LDC-ABD-000-SP implement diagnostics for open/short detection?
The MLX90365LDC-ABD-000-SP performs continuous open-circuit and short-to-rail diagnostics on its output stage. When enabled, it monitors OUT pin voltage during defined diagnostic windows and reports faults via dedicated diagnostic output level shifts (e.g., Dsat_lo/Dsat_hi). These diagnostics require no external components and are configurable via EEPROM DIAG mode settings.
Can the MLX90365LDC-ABD-000-SP be used in ASIL-B compliant systems?
Yes, the MLX90365LDC-ABD-000-SP supports ASIL-B compliance through integrated diagnostics (open/short, supply monitoring), AEC-Q100 qualification, and failure-in-time (FIT) data provided by Melexis. However, full ASIL-B implementation requires system-level validation including safe state management, diagnostic coverage analysis, and hardware fault tolerance assessment per ISO 26262.
