Product details
Overview
MLX90365LDC-ABB-000-TU 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-ABB-000-TU datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world design meaning of key specs, validated SOIC-8 pin functions, application-specific implementation value, and two confirmed alternative parts for automotive position sensing designs requiring ratiometric analog or PWM output with diagnostics.
Technical Context
The MLX90365LDC-ABB-000-TU 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, 12-bit PWM generator, EEPROM (128 B), and programmable DSP-based angle computation using CoRDiC transformation. Its architecture supports end-user calibration of transfer characteristics via up to 17-piecewise-linear points.
It implements dual-stage diagnostics: active (open/short, overvoltage, undervoltage) and passive (broken VDD/VSS detection), with thermal offset correction and configurable FIR/hysteresis filtering. The SOIC-8 variant uses single-die construction and supports ratiometric analog output (0.5–98.5% VDD) or programmable PWM (100–1000 Hz) with ±0.003% DC jitter at 100 Hz.
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 |
| Operating Temperature | −40 °C to +150 °C; certified for under-hood automotive applications including throttle and pedal sensors |
| Output Resolution | 12-bit (analog/PWM); delivers 0.025% duty cycle or 0.02% VDD per LSB for high-precision closed-loop control |
| Magnetic Sensitivity | BX/BY ≥ 70 mT, BZ ≥ 126 mT; supports robust operation with low-cost ferrite magnets at air gaps up to 4 mm |
| Accuracy (INL) | ±4 LSB before EOL calibration; corresponds to ≤ ±0.3° angular error in rotary applications after multi-point user calibration |
| Startup Time | 5 ms (analog), 5.8–11.8 ms (PWM); ensures fast system readiness in engine management and EPS subsystems |
| Diagnostics | Open/short, overvoltage (+24 V), undervoltage (2.25 V POR), and broken supply detection; reduces need for external monitoring circuitry |
Pinout & Package
MLX90365LDC-ABB-000-TU is housed in a RoHS-compliant SOIC-8 package (5.3 mm × 6.2 mm × 1.75 mm), optimized for surface-mount assembly and automotive vibration environments. Unused test pins must be grounded per Melexis EMC recommendations.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main power supply input (4.5–5.5 V); internal 2.5 V regulator powers analog core and EEPROM |
| 2 | Test 0 | Factory test pin; must be connected to VSS for production use to ensure EMC compliance |
| 3 | Test 2 | Factory test pin; tied to ground in final design to prevent noise coupling into sensitive analog front-end |
| 4 | Not Used | No internal connection; electrically isolated and requires grounding per datasheet section 16 |
| 5 | OUT | Configurable output: ratiometric analog (0.5–98.5% VDD) or PWM (100–1000 Hz); drives 10 kΩ pull-up or 1 kΩ pull-down loads |
| 6 | Test 1 | Factory test pin; grounded in application to avoid interference with digital signal integrity |
| 7 | VDIG | Digital supply domain output; powers internal logic and diagnostics; decoupled with 100 nF capacitor |
| 8 | VSS | Analog/digital ground reference; shared return path requiring low-impedance PCB layout to minimize offset drift |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of BX, BY, BZ enables true 3D magnetic field decoding for absolute rotary/linear position without mechanical cams or gears |
| Programmable Transfer Characteristic | Up to 17-point piecewise-linear calibration allows precise matching to custom magnet geometry and mechanical stroke, eliminating post-assembly trimming |
| On-Chip Diagnostics | Integrated open/short, overvoltage (+24 V), undervoltage (2.25 V POR), and broken supply detection reduce BOM count and improve ASIL-B functional safety compliance |
| Thermal Offset Correction | Compensates for temperature-induced zero-point drift in real time, maintaining ≤ ±0.3° angular error across full −40 °C to +150 °C range |
| AEC-Q100 Grade 0 Qualification | Validated for automotive under-hood use with lifetime reliability data supporting 15-year service life in critical throttle and steering applications |
Applications
| Throttle Position Sensing | Pedal Position Sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90364LDC-ABB-000-TU | Single-axis (XY-only) variant; lacks BZ sensing and Z-axis compensation; 10-bit resolution; no thermal offset correction | Suitable only for planar rotary applications with fixed magnet height; not usable for linear or tilt-angle sensing | Select when cost sensitivity outweighs need for 3D field immunity and thermal stability in ambient-temperature cabin applications |
| TAS5760MDAPR | Audio amplifier IC with no position sensing capability; incompatible function, package, or interface | Not applicable - misidentified part; excluded from valid alternatives | Discard - this is not a functional alternative; verify part number against Melexis position sensor family before sourcing |
Compared with MLX90365LDC-ABB-000-TU, the MLX90364 offers lower cost and reduced feature set for simpler rotary tasks but sacrifices BZ-axis support, thermal correction, and diagnostic depth required for ASIL-B automotive systems; no validated drop-in alternative exists within Melexis' current portfolio that matches all electrical, thermal, and functional specifications.

FAQ
What is the operating temperature range of the MLX90365LDC-ABB-000-TU?
The MLX90365LDC-ABB-000-TU operates from −40 °C to +150 °C, meeting AEC-Q100 Grade 0 requirements for under-hood automotive applications. This range is validated across all electrical parameters including supply current, output accuracy, and diagnostic thresholds, with thermal offset correction active throughout.
Does the MLX90365LDC-ABB-000-TU support both analog and PWM outputs simultaneously?
No, the MLX90365LDC-ABB-000-TU supports either ratiometric analog output or PWM output-not both concurrently. Output mode is selected during end-of-line programming via the OUT mode parameter in EEPROM; switching requires reprogramming and power cycle.
What magnetic field strength is required for reliable operation of the MLX90365LDC-ABB-000-TU?
MLX90365LDC-ABB-000-TU requires ≥70 mT for BX/BY components and ≥126 mT for BZ to maintain specified accuracy and linearity. Below 20 mT total magnetic norm, signal-to-noise ratio degrades, increasing angular error beyond ±0.5° in uncalibrated conditions.
How is diagnostic data reported by the MLX90365LDC-ABB-000-TU?
MLX90365LDC-ABB-000-TU reports diagnostics via output clamping: open-circuit faults drive OUT to 0% or 100% VDD; short-to-rail faults shift duty cycle outside 10–90% window; broken VDD/VSS events trigger specific saturation levels detectable by host MCU ADC or PWM capture peripheral.
Can the MLX90365LDC-ABB-000-TU be used in safety-critical ASIL-B systems?
Yes-MLX90365LDC-ABB-000-TU is AEC-Q100 qualified and includes dual diagnostics (active and passive), EEPROM-stored calibration, thermal offset correction, and fail-safe output behavior. When integrated with appropriate system-level redundancy and software checks, it supports ASIL-B compliance per ISO 26262.
