Product details
Overview
MLX90365KDC-ABB-000-RE from Melexis is an AEC-Q100 qualified monolithic Triaxis® Hall-effect position sensor IC in SOIC-8 package, delivering 12-bit analog or PWM output with programmable transfer characteristics for absolute rotary and linear position sensing. It operates across −40 °C to +125 °C, supports ratiometric analog output compatible with potentiometer interfaces, and integrates on-chip diagnostics including open/short detection and over-voltage protection - used in automotive pedal and steering wheel position sensing.
For engineers reviewing the MLX90365KDC-ABB-000-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact pin functions, real-world application mappings, and validated alternative options - all grounded in Melexis' official Revision 5.9 datasheet and packaging documentation.
Technical Context
The MLX90365KDC-ABB-000-RE uses Triaxis® Hall technology to measure orthogonal (BX, BY) and parallel (BZ) magnetic flux components, enabling absolute angular decoding (0–360°) or linear displacement via coordinate rotation (CoRDiC). Its integrated 16-bit RISC microcontroller runs firmware for real-time DSP, thermal offset correction, and multi-point piecewise-linear transfer function programming.
It features dual-output capability: a 12-bit ratiometric analog output (0–100% VDD) and a programmable 12-bit PWM output (100–1000 Hz), both with ≤±4 LSB INL before calibration. The SOIC-8 variant implements single-die architecture with dedicated VDD, VSS, OUT, VDIG, and test pins - no redundancy - and supports diagnostic modes via configurable DIAG pin behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V nominal; enables direct interface with 5 V automotive ECUs without external regulation. |
| Analog Output Resolution | 12-bit DAC (0.02–5% VDD/LSB); provides potentiometer-equivalent linearity for legacy analog signal chains. |
| PWM Frequency Range | 100–1000 Hz, ±1% initial tolerance; supports robust digital position feedback in noisy environments with configurable jitter (<±0.035% DC). |
| Operating Temperature | −40 °C to +125 °C (K-grade); certified AEC-Q100 Grade 0 for under-hood automotive use. |
| Magnetic Sensitivity | BX/BY ≥70 mT, BZ ≥126 mT; allows compact magnet placement with IMC gain of 1.2–1.8× in X/Y axis. |
| Diagnostic Coverage | Open/short circuit detection, over-voltage (24 V abs max), under-voltage lockout (2.25 V POR), and thermal offset drift compensation (±60 LSB15). |
| Package | SOIC-8, RoHS-compliant; footprint-compatible with standard 1.27 mm pitch PCB assembly and reflow processes. |
Pinout & Package
MLX90365KDC-ABB-000-RE is housed in an 8-pin SOIC package (3.9 mm × 4.9 mm, 1.27 mm pitch), optimized for surface-mount automotive applications requiring high EMC immunity and thermal stability up to +125 °C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VDD | Primary power supply input | Accepts 4.5–5.5 V; includes over-voltage protection up to +24 V and reverse voltage clamp at −12 V. |
| 2: Test 0 | Factory test and programming pin | Used during wafer sort and EOL programming; must be tied to GND per Melexis EMC recommendation. |
| 3: Test 2 | Factory test and programming pin | Reserved for internal calibration; not user-accessible in final application; connect to GND for noise suppression. |
| 4: Not Used | No internal connection | Electrically isolated; must be connected to VSS to minimize EMI and improve EMC performance. |
| 5: OUT | Main analog/PWM output terminal | Configurable as ratiometric analog (0–100% VDD) or PWM (100–1000 Hz); push-pull or open-drain selectable via programming. |
| 6: Test 1 | Factory test and programming pin | Supports diagnostic mode entry; tie to GND unless actively used in production test flow. |
| 7: VDIG | Digital supply reference | Internally regulated 2.5 V rail for ADC/DSP; decoupling capacitor required between VDIG and VSS for noise immunity. |
| 8: VSS | Ground reference | Primary analog/digital return path; must be low-impedance and star-connected to avoid ground bounce in high-diagnostic-integrity systems. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-axis magnetic sensing | Simultaneous measurement of BX, BY, BZ enables true 360° absolute angle or stroke position without mechanical stops or multi-sensor assemblies. |

| On-chip thermal offset correction | Compensates for temperature-induced zero-point drift (±60 LSB15) in real time using internal DSP - critical for throttle and pedal sensors. |
| Integrated diagnostics | Hardware-level open/short detection, supply monitoring (MT4V/MT7V), and field strength validation reduce system-level fault detection latency. |
| AEC-Q100 Grade 0 qualification | Validated for automotive under-hood operation (−40 °C to +125 °C) with full traceability via 48-bit unique ID and EEPROM endurance >100k cycles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90364KDC-ABB-000-RE | Single-axis (BZ-only) variant; no XY vector processing or CoRDiC engine; 10-bit resolution; no thermal offset correction. | Limited to linear or unidirectional rotary applications (e.g., seat position); unsuitable for 360° steering or throttle sensing. | Select only when cost sensitivity outweighs angular accuracy and diagnostic depth requirements. |
| AMS AS5055A-BQFT | 14-bit SPI output only; no analog/PWM dual-mode; requires external MCU for angle computation; no integrated diagnostics or EEPROM programmability. | Requires host processor for trigonometric calculation; lacks self-contained diagnostics and failsafe signaling needed in ASIL-B systems. | Prefer for non-automotive industrial encoders where SPI interface and higher raw resolution are prioritized over functional safety integration. |
Compared with MLX90365KDC-ABB-000-RE, the MLX90364 offers lower cost but sacrifices Triaxis® vector capability and thermal compensation, while the AS5055A demands external processing and lacks built-in diagnostics - making the MLX90365KDC-ABB-000-RE uniquely suited for automotive-grade, self-contained absolute position sensing.

FAQ
What is the operating temperature range of the MLX90365KDC-ABB-000-RE?
The MLX90365KDC-ABB-000-RE is rated for −40 °C to +125 °C ambient operation (K-grade), fully qualified to AEC-Q100 Grade 0 standards. This range covers under-hood automotive environments including engine compartments and brake modules. Thermal offset correction and IMC gain stability are maintained across this span, with documented drift limits of ±60 LSB15 for DSP input offset and ±0.5% for sensitivity mismatch.
Does the MLX90365KDC-ABB-000-RE support both analog and PWM outputs simultaneously?
No - the MLX90365KDC-ABB-000-RE supports either analog (ratiometric) or PWM output mode, selected permanently during end-of-line programming. The output stage is configured at factory or by user via EEPROM write to the OUT mode register (bit #0 in PPAR). Simultaneous dual-output is not implemented; switching requires reprogramming and power cycle.
How is the MLX90365KDC-ABB-000-RE calibrated for specific mechanical setups?
The MLX90365KDC-ABB-000-RE supports up to 17-point piecewise-linear transfer function programming via its onboard EEPROM. Users define breakpoints and output values corresponding to known mechanical positions (e.g., 0°, 90°, 180°, 270°, 360°), enabling precise compensation for magnet misalignment, mechanical hysteresis, or non-uniform air gaps - all without host MCU involvement.
What diagnostic capabilities does the MLX90365KDC-ABB-000-RE provide?
The MLX90365KDC-ABB-000-RE delivers hardware-level diagnostics including open/short detection on the OUT pin, supply voltage monitoring (MT4V/MT7V thresholds), broken VSS/VDD detection, and magnetic field strength validation. Diagnostic status is reported via dedicated output levels (e.g., Dsat_lo/Dsat_hi) or encoded in PWM duty cycle clamping - enabling immediate ECU-level fault classification.
Is the MLX90365KDC-ABB-000-RE pin-compatible with other MLX90365 variants?
Yes - all SOIC-8 packaged MLX90365 variants (e.g., MLX90365EDC-ACD-000-RE, MLX90365LDC-ACE-000-RE) share identical pinout, footprint, and electrical interface. Differences lie in temperature grade (E/K/L), EEPROM content (standard vs. preprogrammed), and feature enablement (e.g., thermal offset correction in ACE versions), not physical connectivity.
