Product details
Overview
MLX90365KDC-ABB-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-ABB-000-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 pin mapping, programmable transfer characteristic details, diagnostic behavior, and validated alternative options for automotive position sensing designs.
Technical Context
The MLX90365KDC-ABB-000-SP integrates a Triaxis® Hall front-end sensing all three magnetic flux 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. Its DSP performs real-time coordinate rotation (CoRDiC) to compute absolute angle or linear position from raw sine/cosine signals.
It supports end-user programming of output mode (analog ratiometric or PWM), multi-point piecewise-linear transfer characteristic (4- or 17-point), clamping thresholds, filter settings (3 levels), and diagnostic parameters including open/short detection and broken-track diagnostics. Thermal offset correction is implemented in firmware with ±60 LSB15 drift over temperature for suffix K.

| 2 | Test 0 | Factory test pad; not connected in application; tie to ground for EMC compliance. |
| 3 | Test 2 | Factory test pad; not connected in application; tie to ground for EMC compliance. |
| 4 | Not Used | No internal connection; must be grounded to minimize EMI coupling. |
| 5 | OUT | Programmable output: ratiometric analog voltage (0.5–98.5%VDD) or PWM signal (100–1000 Hz). |
| 6 | Test 1 | Factory test pad; not connected in application; tie to ground for EMC compliance. |
| 7 | VDIG | Digital supply reference; decouples digital noise from analog section; connect to local 5 V rail with 100 nF capacitor. |
| 8 | VSS | Ground reference for analog and digital domains; requires low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of BX, BY, BZ enables single-chip absolute angle computation without external magnets or complex PCB layouts. |
| Programmable Transfer Characteristic | Up to 17-point piecewise-linear calibration allows precise matching to mechanical stroke or rotation profile, reducing post-assembly trimming. |
| Selectable Output Mode | Runtime-configurable analog (ratiometric) or PWM output eliminates need for external ADC or pulse decoder in ECU interface. |
| On-Chip Diagnostics | Integrated open/short, broken-track, and field-strength diagnostics reduce BOM count and improve ASIL-B functional safety compliance. |
| Thermal Offset Correction | Firmware-based compensation limits angular error drift to ±0.3° over −40 °C to +125 °C, critical for throttle position stability. |
