Overview
MLX90365KGO-ACD-000-SP from Melexis is an AEC-Q100 qualified Triaxis® Hall-effect absolute position sensor IC in TSSOP-16 package, operating from −40 °C to +150 °C, delivering 12-bit analog or PWM output with 10-bit thermal accuracy and open/short diagnostics for automotive pedal and steering wheel position sensing.
For engineers reviewing the MLX90365KGO-ACD-000-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for high-reliability non-contacting position sensing in safety-critical systems.
Technical Context
The MLX90365KGO-ACD-000-SP integrates a Triaxis® Hall sensor front-end capturing BX, BY, and BZ magnetic field components, feeding a 16-bit RISC DSP that computes absolute angular or linear position via CoRDiC-based rectangular-to-polar transformation. Its dual-die TSSOP-16 architecture enables full redundancy for ASIL-B compliance.
It supports programmable multi-point piecewise-linear transfer characteristics, selectable ratiometric analog or PWM output modes, on-chip thermal offset correction, and configurable diagnostics including broken VDD/VSS detection - all calibrated and stored in 128 B EEPROM with 48-bit unique ID.

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-ACD-000-SP | SOIC-8 single-die variant; −40 °C to +125 °C; no hardware redundancy | Suitable for cost-sensitive non-safety-critical applications like HVAC dampers or industrial joysticks | Select when ASIL-B redundancy is unnecessary and PCB space is constrained. |
| MLX90365LGO-ACE-000-SP | TSSOP-16 dual-die with enhanced thermal offset correction firmware (AxE version) | Required for high-precision applications demanding <±0.3° angular error over full temperature range | Choose when thermal stability exceeds standard MLX90365KGO-ACD-000-SP specifications. |
Compared with MLX90365KGO-ACD-000-SP, the SOIC-8 MLX90365KDC-ACD-000-SP reduces footprint and cost but sacrifices redundancy and extended temperature margin, while the MLX90365LGO-ACE-000-SP adds tighter thermal compensation at the expense of higher firmware complexity and qualification overhead.

FAQ
What is the maximum operating temperature of the MLX90365KGO-ACD-000-SP?
The MLX90365KGO-ACD-000-SP is rated for operation from −40 °C to +150 °C, corresponding to the 'L' temperature grade and AEC-Q100 Grade 0 qualification. This enables deployment in engine bay, transmission, and brake module environments where ambient temperatures exceed 125 °C. The device maintains specified accuracy and diagnostic functionality across this full range, with thermal offset correction active in real time.
Does the MLX90365KGO-ACD-000-SP support both analog and PWM output simultaneously?
No, the MLX90365KGO-ACD-000-SP supports only one output mode at a time - either ratiometric analog or PWM - selected during end-user programming via EEPROM configuration. Both OUT1 and OUT2 pins reflect the same selected mode. Simultaneous dual-mode output is not supported; however, the dual-die architecture allows independent signal processing paths for redundancy, not functional diversity.
How is redundancy implemented in the MLX90365KGO-ACD-000-SP TSSOP-16 package?
Redundancy in the MLX90365KGO-ACD-000-SP is implemented via two physically separate silicon dies in one TSSOP-16 package, each with independent VDD1/VSS1/VDIG1 and VDD2/VSS2/VDIG2 power domains, isolated signal paths, and dedicated OUT1/OUT2 outputs. This hardware separation enables cross-die comparison for fault detection and supports ASIL-B system-level requirements without external arbitration circuitry.
Can the MLX90365KGO-ACD-000-SP be used with off-axis magnets?
Yes, the MLX90365KGO-ACD-000-SP is specifically designed for off-axis magnet configurations - its Triaxis® architecture measures BX, BY, and BZ components orthogonally and parallel to the die surface, enabling accurate position decoding from side-mounted or axial-field magnets. The datasheet specifies minimum field norms (20 mT) and saturation limits (±1 T), and application diagrams validate use with diametrically magnetized ring magnets and linear sliders.
What diagnostic features are enabled by default on the MLX90365KGO-ACD-000-SP?
By default, the MLX90365KGO-ACD-000-SP enables open/short circuit detection on the output pin, under-voltage lockout (MT4V threshold), over-voltage protection (up to +24 V), and basic supply rail monitoring. Field strength and PWM-specific diagnostics require explicit configuration via the DIAG mode and DIAG Level parameters in EEPROM. All diagnostics generate status flags accessible through the output waveform or external monitoring logic.
