Product details
Overview
MLX90365EDC-ABB-000-TU from Melexis is an AEC-Q100 qualified absolute rotary/linear position sensor IC using Triaxis® Hall technology in SOIC-8 package, delivering 12-bit analog or PWM output with ±0.3° angular accuracy at 25°C, open/short diagnostics, and automotive-grade operation from −40°C to +150°C for throttle, pedal, and steering position sensing.
For engineers reviewing the MLX90365EDC-ABB-000-TU datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation value, and two confirmed alternative parts with functional and packaging distinctions.
Technical Context
The MLX90365EDC-ABB-000-TU integrates a Triaxis® Hall front-end sensing BX, BY, and BZ magnetic field components, feeding a 16-bit RISC DSP that computes absolute angle or linear displacement via CoRDiC-based rectangular-to-polar transformation. Its on-chip EEPROM stores programmable transfer characteristics (4- or 17-point piecewise-linear), clamping thresholds, and diagnostic settings.
It supports dual output modes: ratiometric analog (0–100% VDD) with 12-bit DAC resolution and PWM (100–1000 Hz, ±0.003% DC jitter at 100 Hz) with thermal offset correction enabled by default in ABB variant. The SOIC-8 package houses a single die with integrated 2.5V regulator, overvoltage protection up to +24 V, and under-voltage detection at 3.8–4.2 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V nominal; enables direct connection to standard 5 V automotive rails without external regulation. |
| Analog Output Resolution | 12-bit (0.02–5% VDD/L); delivers 0.0879°/LSB angular step for high-fidelity position feedback in closed-loop control. |
| PWM Frequency Range | 100–1000 Hz programmable; allows EMI-optimized selection-e.g., 250 Hz avoids audible noise while maintaining <13 ms start-up. |
| Angular Accuracy (XY) | ±0.3° at 25°C after factory trim; ensures sub-degree repeatability in pedal or throttle position systems without end-of-line calibration. |
| Operating Temperature | −40°C to +150°C; supports placement near engine compartments or brake assemblies without derating. |
| Diagnostics | Open/short, broken VDD/VSS, field strength, and PWM diagnostic flags; reduces need for external monitoring circuitry in ASIL-B designs. |
| Magnetic Sensitivity | BX/BY ≥70 mT, BZ ≥126 mT; compatible with low-cost NdFeB magnets at air gaps up to 4 mm in rotary configurations. |
Pinout & Package
MLX90365EDC-ABB-000-TU uses RoHS-compliant SOIC-8 package (5.3 mm × 6.2 mm × 1.75 mm), optimized for surface-mount reflow and automotive vibration resistance. Unused pins (2, 3, 4, 6, 7) must be tied to ground per Melexis EMC recommendations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – VDD | Power supply input | Accepts 4.5–5.5 V; internal overvoltage protection up to +24 V prevents latch-up during load dump. |
| 2 – Test 0 | Factory test pin | No user function; must be connected to VSS per datasheet to ensure EMC compliance and avoid floating node noise. |
| 3 – Test 2 | Factory test pin | Unused in application; grounded to suppress coupling into sensitive analog front-end paths. |
| 4 – Not Used | Unbonded pad | No internal connection; tie to VSS to minimize parasitic capacitance and improve signal integrity. |
| 5 – OUT | Programmable output | Configurable as ratiometric analog (0–100% VDD) or PWM; drives 4.7 kΩ pull-up/pull-down loads directly. |
| 6 – Test 1 | Factory test pin | Reserved for production testing; grounding required to prevent interference with output stage switching. |
| 7 – VDIG | Digital supply rail | Internally regulated 2.5 V for logic and EEPROM; decoupling capacitor (100 nF) mandatory between VDIG and VSS. |
| 8 – VSS | Ground reference | Common return for analog and digital sections; separate ground plane recommended to avoid noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-axis Hall sensing | Measures BX, BY, BZ simultaneously to compute absolute angle or linear stroke without mechanical wipers or potentiometers. |
| Programmable piecewise-linear transfer | Supports 4- or 17-point user-defined calibration curves-enables compensation for magnet nonlinearity and mechanical tolerances in final assembly. |
| On-chip thermal offset correction | Reduces angular drift to ±0.3° over −40°C to +150°C, eliminating need for external temperature sensors or software compensation. |
| Integrated diagnostics | Reports open-circuit, short-circuit, broken supply, and magnetic field faults via dedicated diagnostic flag or clamped output levels. |
| AEC-Q100 Grade 0 qualification | Validated for automotive safety-critical applications including throttle, brake, and steering position sensing up to 150°C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90365KDC-ABD-000-RE | Same SOIC-8 package and Triaxis® core, but rated −40°C to +125°C (K grade) and marked "not recommended for new design" per datasheet. | Limited to under-hood applications below 125°C ambient; lacks thermal offset correction firmware present in ABB version. | Select only for legacy redesign where ABB is unavailable; verify thermal margin and diagnostic feature compatibility. |
| MLX90365LDC-ACD-000-RE | SOIC-8 package, −40°C to +150°C (L grade), standard version without thermal offset correction; requires external calibration for high-temp stability. | Suitable for cost-sensitive industrial linear encoders where ambient stays <125°C and software compensation is acceptable. | Choose when budget constraints outweigh need for guaranteed ±0.3° accuracy over full temp range; confirm EEPROM programming support for required transfer curve. |
Compared with MLX90365EDC-ABB-000-TU, the KDC-ABD-000-RE offers identical pinout but reduced temperature capability and obsolete status, while the LDC-ACD-000-RE extends temperature range without built-in thermal correction-requiring system-level compensation to match ABB's out-of-box accuracy.

FAQ
What is the operating temperature range of the MLX90365EDC-ABB-000-TU?
The MLX90365EDC-ABB-000-TU operates from −40°C to +150°C, certified to AEC-Q100 Grade 0. This range is validated for placement in high-heat zones such as near engines or brake calipers. Its on-chip thermal offset correction maintains ±0.3° angular accuracy across the full span, eliminating need for external temperature compensation in the MLX90365EDC-ABB-000-TU design.
Does the MLX90365EDC-ABB-000-TU support both analog and PWM outputs?
Yes, the MLX90365EDC-ABB-000-TU supports selectable ratiometric analog (0–100% VDD) and PWM (100–1000 Hz) outputs via EEPROM-programmable OUT mode. The analog path features 12-bit DAC resolution with <0.1% ratiometry error; PWM offers ±0.003% duty-cycle jitter at 100 Hz. Both modes are active simultaneously in the MLX90365EDC-ABB-000-TU, enabling dual-signal redundancy or mixed-system interfacing.
How does the Triaxis® technology in the MLX90365EDC-ABB-000-TU differ from standard Hall sensors?
Unlike single-axis Hall sensors, the MLX90365EDC-ABB-000-TU's Triaxis® architecture measures all three orthogonal magnetic field components (BX, BY, BZ) on a single die. This enables true 3D field vector computation-supporting absolute rotary (0–360°), linear, and axial position decoding from one compact SOIC-8 device. The integrated CoRDiC engine performs real-time rectangular-to-polar conversion within the MLX90365EDC-ABB-000-TU, removing host MCU computational load.
What diagnostic capabilities does the MLX90365EDC-ABB-000-TU provide?
The MLX90365EDC-ABB-000-TU includes open/short circuit detection on the output, broken VDD/VSS monitoring, magnetic field strength diagnostics, and PWM-specific fault flags-all configurable via EEPROM. Diagnostic states are reported either through dedicated clamped output levels (e.g., 0% or 100% VDD) or by asserting a diagnostic flag. These features reduce validation effort and simplify functional safety compliance for the MLX90365EDC-ABB-000-TU in ASIL-B systems.
Is the MLX90365EDC-ABB-000-TU pin-compatible with other MLX90365 variants?
Yes, all SOIC-8 variants-including MLX90365EDC-ABB-000-TU, MLX90365KDC-ABD-000-RE, and MLX90365LDC-ACD-000-RE-share identical pinout, footprint, and electrical interface. However, firmware features (e.g., thermal offset correction), temperature grade, and lifecycle status differ. Pin compatibility allows drop-in replacement only when verifying functional equivalence and qualification status for the target application's MLX90365EDC-ABB-000-TU requirements.
