Product details
Overview
MLX90365KDC-ABB-000-TU from Melexis is an AEC-Q100 qualified Triaxis® Hall-effect absolute position sensor IC in SOIC-8 package, operating from −40 °C to +125 °C, delivering 12-bit analog or PWM output with programmable transfer characteristics and on-board diagnostics for rotary/linear position sensing in automotive throttle, pedal, and steering applications.
For engineers reviewing the MLX90365KDC-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, automotive-grade diagnostic capabilities, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The MLX90365KDC-ABB-000-TU integrates a Triaxis® Hall front-end sensing BX, BY, and BZ magnetic field components, feeding a 16-bit RISC microcontroller (2.5 MIPS @ 10 MHz) with DSP-based angle computation using CoRDiC transformation. Its architecture supports end-user programmable 4-point or 17-point piecewise-linear transfer curves and thermal offset correction.
It features dual-output capability: ratiometric analog (0–100% VDD, 12-bit DAC resolution) and configurable PWM (100–1000 Hz, 12-bit duty-cycle resolution), both with open/short diagnostics, over-voltage protection up to +24 V, and under-voltage detection at 3.8–4.2 V. The SOIC-8 variant uses single-die architecture with integrated IMC® magneto-concentrator.

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-ABD-000-RE | Dual-die TSSOP-16 package with full hardware redundancy; higher supply current (2×), separate VDD1/VDD2, VSS1/VSS2, and dual OUT1/OUT2 outputs. | Required for ASIL-D systems needing fault-tolerant dual-channel architecture; not pin-compatible with SOIC-8 MLX90365KDC-ABB-000-TU. | Select when functional safety mandates hardware redundancy; avoid for cost-sensitive single-channel designs. |
| MLX90364KDC-ABB-000-TU | Legacy 10-bit resolution analog/PWM output; no thermal offset correction; identical SOIC-8 package and pinout. | Suitable for non-critical industrial position feedback where <±1° accuracy suffices and thermal drift compensation is unnecessary. | Choose only if legacy design reuse or lower cost outweighs need for 12-bit resolution and on-chip thermal correction. |
Compared with MLX90365KDC-ABB-000-TU, the TSSOP-16 dual-die variant adds hardware-level fault tolerance at higher cost and layout complexity, while the MLX90364 offers identical form factor but sacrifices 2 bits of resolution and thermal stability-making the MLX90365KDC-ABB-000-TU optimal for new automotive designs requiring ASIL-B compliance and precision.

FAQ
What is the operating temperature range of the MLX90365KDC-ABB-000-TU?
The MLX90365KDC-ABB-000-TU is rated for −40 °C to +125 °C ambient operation, matching the K temperature grade defined in Melexis' ordering information. This range is validated per AEC-Q100 Grade 0 stress testing and supports under-hood deployment in engine control modules and transmission control units where thermal cycling and long-term stability are critical. The device maintains specified accuracy and diagnostic functionality across this full span.
Does the MLX90365KDC-ABB-000-TU support both analog and PWM output simultaneously?
No, the MLX90365KDC-ABB-000-TU supports either analog (ratiometric voltage) or PWM output mode-not both concurrently. The output mode is selected during end-user programming via the OUT mode parameter (bit #0 in PPAR register). Once configured, the device operates exclusively in that mode until reprogrammed. Pin 5 (OUT) carries the active signal; no second output channel exists in the SOIC-8 package.
How is the MLX90365KDC-ABB-000-TU calibrated for thermal offset drift?
The MLX90365KDC-ABB-000-TU implements real-time thermal offset correction using internal temperature sensing and factory-trimmed coefficients stored in EEPROM. This correction applies to the DSP input stage and reduces angular error to ≤ ±0.3° over −40 °C to +125 °C. No external calibration is required-the feature is enabled by default and cannot be disabled in standard configurations.
What diagnostic functions are built into the MLX90365KDC-ABB-000-TU?
The MLX90365KDC-ABB-000-TU integrates open/short circuit detection on the output, over-voltage protection (up to +24 V), under-voltage lockout (~4.0 V), broken-track diagnostics for VDD/VSS lines, and field-strength monitoring. Diagnostic status is reported via dedicated flag bits in the internal register map and can trigger clamped output states (e.g., 0% or 100% duty cycle) for fail-safe system response.
Is the MLX90365KDC-ABB-000-TU pin-compatible with other MLX90365 variants?
The MLX90365KDC-ABB-000-TU shares the same SOIC-8 pinout with all other DC-package MLX90365 variants (e.g., MLX90365EDC-ACD-000-RE, MLX90364KDC-ABB-000-TU), including identical VDD, VSS, OUT, and VDIG connections. However, it is not pin-compatible with GO-package (TSSOP-16) variants due to differing pin count, assignment, and dual-die architecture.
