Product details
Overview
MLX90365KDC-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 +125 °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 MLX90365KDC-ABD-000-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact SOIC-8 pin mapping, real-world diagnostic behavior, thermal offset correction capability, and validated automotive alternatives - all grounded in Revision 5.9 (Oct 2018) official specifications.
Technical Context
The MLX90365KDC-ABD-000-SP integrates a Triaxis® Hall front-end sensing all three magnetic field components (BX, BY, BZ), a 16-bit RISC microcontroller running at 10 MHz (2.5 MIPS), 12-bit DAC for analog output, and 12-bit PWM generator with programmable frequency (100–1000 Hz). Its DSP performs real-time coordinate rotation (CoRDiC) to compute absolute angle from raw sine/cosine signals with 15-bit internal ADC resolution.
It supports end-user programmable transfer characteristics via multi-point piecewise-linear calibration (4-pt or 17-pt LNR), configurable filter modes (0–2) affecting step response time (657–1494 μs), and dual diagnostic modes (active/passive) including broken VDD/VSS detection. Thermal offset drift is compensated per die version, with ABD-000 supporting standard thermal correction.

Pinout & Package
MLX90365KDC-ABD-000-SP uses the SOIC-8 package (8-pin, 3.9 mm × 4.9 mm, 1.27 mm pitch), with pins 2, 3, 4, and 6 designated as test points and pin 4 marked "Not Used" - all unused pins must be connected to ground per EMC recommendations.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main supply input (4.5–5.5 V); powers analog front-end, DSP, EEPROM, and output stage. |
| 2 | Test 0 | Factory test access point; must be grounded for optimal EMC performance in production layout. |
| 3 | Test 2 | Factory test access point; tied to ground in final design to suppress noise coupling. |
| 4 | Not Used | No internal connection; requires grounding to minimize radiated emissions and improve signal integrity. |
| 5 | OUT | Programmable analog (ratiometric) or PWM output; drives 4.7 kΩ pull-up/pull-down loads with 0.5–3% VDD saturation levels. |
| 6 | Test 1 | Factory test access point; grounded in application to prevent parasitic oscillation and EMI. |
| 7 | VDIG | Digital supply rail for output stage and diagnostics; internally regulated from VDD and decoupled externally. |
| 8 | VSS | Ground reference for analog and digital sections; shared return path requiring low-impedance PCB connection. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-axis Hall sensing | Measures BX, BY, BZ simultaneously to compute absolute angle or linear position without mechanical wipers or gears. |
| Programmable transfer characteristic | Supports 4-point or 17-point piecewise-linear calibration, enabling precise matching to custom magnetic circuits and mechanical stroke profiles. |
| Selectable output mode | Configurable ratiometric analog voltage or PWM output - both deliver 12-bit resolution and support same magnetic field input. |
| On-board diagnostics | Detects open/short output, over/under-voltage, broken VDD/VSS, and magnetic field strength faults - reducing system-level BOM count. |
| Thermal offset correction | Compensates for temperature-induced zero-point drift in both analog and PWM outputs, maintaining ≤±0.3° angular error across −40 °C to +125 °C. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365KGO-ACD-000-RE | TSSOP-16 dual-die package 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 MLX90365KDC-ABD-000-SP. | Select when functional safety mandates hardware redundancy; avoid if board space or cost constraints favor single-die SOIC-8. |
| MLX90364KDC-ABD-000-SP | Legacy 10-bit resolution version; lacks 17-point LNR programming, thermal offset correction, and enhanced diagnostics. | Suitable only for non-safety-critical linear/rotary sensing where <±2° accuracy suffices and EOL calibration is manual. | Choose only for legacy redesigns; MLX90365KDC-ABD-000-SP offers measurable improvement in resolution, linearity, and diagnostic coverage. |
Compared with MLX90365KDC-ABD-000-SP, the TSSOP-16 MLX90365KGO-ACD-000-RE adds hardware redundancy but increases PCB area and power; the MLX90364KDC-ABD-000-SP reduces resolution and diagnostic depth while retaining SOIC-8 footprint - making MLX90365KDC-ABD-000-SP the optimal balance of precision, safety, and integration for new K-grade automotive designs.

FAQ
What is the operating temperature range of the MLX90365KDC-ABD-000-SP?
The MLX90365KDC-ABD-000-SP is rated for −40 °C to +125 °C ambient operation (K-grade), fully qualified to AEC-Q100 Rev G standards. This range covers under-hood locations such as throttle bodies and brake pedals, and its thermal offset correction maintains angular accuracy within ±0.3° across the full span. The SOIC-8 package supports standard lead-free reflow profiles up to 260 °C peak.
Does the MLX90365KDC-ABD-000-SP support both analog and PWM output modes?
Yes, the MLX90365KDC-ABD-000-SP supports selectable ratiometric analog voltage output (0.5–98.5% VDD) and programmable PWM output (100–1000 Hz, 12-bit resolution). Both modes are configured via EEPROM programming and share identical magnetic field input processing - enabling seamless migration between signal types without hardware changes. Output mode selection is retained after power cycling.
How does the MLX90365KDC-ABD-000-SP perform diagnostics?
The MLX90365KDC-ABD-000-SP implements active diagnostics (open/short output, over/under-voltage) and passive diagnostics (broken VDD/VSS detection), all reported via dedicated output states. Diagnostic thresholds - such as MT4V (3.8–4.2 V) and HPOR (2.0–2.5 V) - are factory-trimmed and temperature-compensated. No external components are required; diagnostics operate continuously during normal operation and do not affect output timing.
Is the MLX90365KDC-ABD-000-SP pin-compatible with other MLX90365 variants?
The MLX90365KDC-ABD-000-SP shares the SOIC-8 pinout with all DC-package MLX90365 variants (e.g., ACD-000, ACE-000), including identical VDD, VSS, OUT, and VDIG connections. However, it is not pin-compatible with TSSOP-16 GO-package versions due to differing pin count, assignment, and dual-die architecture. Unused test pins (2, 3, 4, 6) must be grounded per datasheet Section 4 and Figure 16.1.
What magnetic field strength is required for reliable operation of the MLX90365KDC-ABD-000-SP?
The MLX90365KDC-ABD-000-SP requires BX/BY ≥70 mT and BZ ≥126 mT for full-scale operation, with optimal performance above 20 mT magnetic flux norm (√[BX² + BY² + (BZ/1.2)²]). Below 20 mT, SNR degrades slightly; above 70 mT, IMC® saturation increases linearity error. Standard ferrite or NdFeB magnets sized 3×2×1 mm at 1–3 mm air gap meet these requirements in typical rotary and linear configurations.
