Product details
Overview
MLX90365KGO-ABD-000-SP from Melexis is an AEC-Q100 qualified Triaxis® Hall-effect absolute position sensor IC in TSSOP-16 package, delivering 12-bit analog or PWM output with ±0.3° angular accuracy at 25°C, thermal offset correction, and dual-die redundancy for automotive pedal and steering wheel position sensing.
For engineers reviewing the MLX90365KGO-ABD-000-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, and two confirmed alternative parts for functional substitution in safety-critical linear/rotary sensing systems.
Technical Context
The MLX90365KGO-ABD-000-SP integrates a Triaxis® Hall front-end sensing BX, BY, and BZ magnetic field components, feeding a 16-bit RISC microcontroller with 10 kB ROM and 384 B RAM to compute absolute angle or linear displacement via CoRDiC-based rectangular-to-polar conversion. Its dual-die TSSOP-16 architecture enables full hardware redundancy per AEC-Q100 Grade 0 requirements.
It supports programmable multi-point piecewise-linear transfer characteristics (4- or 17-point), selectable ratiometric analog or PWM output modes, and on-chip diagnostics including open/short detection, over-voltage protection, and broken VDD/VSS monitoring - all operating across −40°C to +150°C ambient temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V nominal; supports robust operation under automotive battery transients up to +24 V absolute max. |
| Output Resolution | 12-bit (0.025% duty cycle/LSB for PWM; 0.02%VDD/LSB for analog), enabling sub-degree angular precision in rotary applications. |
| Angular Accuracy | ±0.3° at 25°C (XY axis), with thermal drift ≤0.01°/°C - critical for throttle and ride height control stability. |
| Operating Temperature | −40°C to +150°C (Grade L); qualified to AEC-Q100 Rev G for under-hood and chassis-mounted automotive use. |
| Magnetic Range | BX/BY up to 70 mT, BZ up to 126 mT; supports compact magnet designs with IMC gain tuning (k = 1.0–1.5). |
| Diagnostics | On-chip open/short, over-voltage, under-voltage, and broken-track detection with dedicated diagnostic output levels. |
| Refresh Rate | 275–305 μs per measurement cycle; ensures <3.5 kHz effective sampling for fast-response pedal actuation. |
Pinout & Package
TSSOP-16 package with dual-die redundancy; RoHS compliant; 4.4 mm × 5.0 mm footprint; 1.2 mm height; exposed pad recommended for thermal and EMC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDIG1 | Digital supply for Die 1; decoupling required near pin to suppress switching noise coupling into analog path. |
| 2 | VSS1 | Ground reference for Die 1; must be connected to system ground plane with low-inductance path for EMC compliance. |
| 3 | VDD1 | Analog supply for Die 1; separate from VDIG1 to isolate analog core from digital switching transients. |
| 4 | Test 01 | Factory test pin; not connected in end application; tie to VSS1 per datasheet for optimal EMC behavior. |
| 5 | Test 22 | Factory test pin; unused in production; connect to VSS1 to minimize parasitic antenna effects. |
| 6 | OUT2 | Redundant output from Die 2; matches OUT1 timing and format; enables cross-checking in ASIL-B/C systems. |
| 7 | Not Used | No internal connection; must be tied to VSS1 to prevent floating node noise injection. |
| 8 | VSS2 | Ground reference for Die 2; independent return path required to maintain isolation between redundant channels. |
| 9 | VDIG2 | Digital supply for Die 2; routed separately from VDIG1 to avoid shared-impedance coupling. |
| 10 | VDD2 | Analog supply for Die 2; isolated routing preserves signal integrity for fault-tolerant comparison logic. |
| 11 | Test 02 | Factory test pin; tie to VSS2 to reduce radiated emissions and improve ESD immunity. |
| 12 | Test 21 | Factory test pin; connect to VSS2 to eliminate unintended resonance in high-frequency PCB layouts. |
| 13 | Not Used | No internal bond; electrically floating; grounding prevents capacitive coupling to sensitive Triaxis® inputs. |
| 14 | OUT1 | Main output from Die 1; configurable as ratiometric analog (0.5–98%VDD) or PWM (100–1000 Hz). |
| 15 | Test 11 | Factory test pin; tie to VSS2; omission risks increased susceptibility to conducted RF interference. |
| 16 | Test 12 | Factory test pin; grounded per datasheet recommendation to stabilize internal voltage references. |
Key Features
| Feature | Design Value |

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-RE | SOIC-8 single-die variant; no hardware redundancy; 125°C max ambient; lacks dual-channel isolation. | Suitable for cost-sensitive non-safety-critical applications like HVAC damper control where ASIL compliance is not required. | Select when board space is constrained and functional safety is not mandated; verify magnetic circuit compatibility with SOIC-8 sensitive spot location. |
| MLX90375KGO-ABE-000-RE | Successor generation with enhanced 14-bit resolution, lower INL (±0.5°), and extended magnetic range (BX/BY up to 100 mT). | Targets next-gen ADAS and x-by-wire systems requiring higher accuracy and wider dynamic range than MLX90365KGO-ABD-000-SP supports. | Choose for new designs needing improved linearity and future-proofing; note different EEPROM programming interface and firmware update path. |
Compared with MLX90365KGO-ABD-000-SP, the SOIC-8 MLX90365KDC-ACD-000-RE reduces footprint and cost but removes hardware redundancy needed for ASIL-B, while the MLX90375KGO-ABE-000-RE increases resolution and accuracy at the expense of backward compatibility and legacy toolchain support.

FAQ
What is the operating temperature range of the MLX90365KGO-ABD-000-SP?
The MLX90365KGO-ABD-000-SP operates from −40°C to +150°C ambient temperature and is qualified to AEC-Q100 Grade L. This range supports placement in demanding under-hood locations such as throttle bodies and suspension modules, where sustained high temperatures require guaranteed parametric performance without derating.
Does the MLX90365KGO-ABD-000-SP support both analog and PWM output modes?
Yes, the MLX90365KGO-ABD-000-SP supports selectable ratiometric analog output (0.5–98%VDD) and PWM output (100–1000 Hz programmable frequency). Output mode is configured via EEPROM programming; both modes deliver 12-bit resolution and include diagnostics, making MLX90365KGO-ABD-000-SP compatible with existing potentiometer interfaces and modern microcontroller capture peripherals.
Is the MLX90365KGO-ABD-000-SP pin-compatible with other MLX90365 variants?
No - the MLX90365KGO-ABD-000-SP uses the TSSOP-16 dual-die package with 16 pins and dedicated redundant supply/ground/output terminals, whereas SOIC-8 variants (e.g., MLX90365KDC-ACD-000-RE) have only 8 pins and no hardware redundancy. PCB layout and schematic must be redesigned to accommodate the TSSOP-16 footprint and dual-channel routing requirements of MLX90365KGO-ABD-000-SP.
What diagnostic capabilities does the MLX90365KGO-ABD-000-SP provide?
The MLX90365KGO-ABD-000-SP provides open/short circuit detection on the output, over-voltage and under-voltage monitoring, broken VDD/VSS tracking, and field strength diagnostics. Diagnostic status is reported via dedicated output levels (e.g., BVSSPD, BVDDPU) that interface directly with host microcontrollers, enabling real-time fault classification without additional external circuitry in MLX90365KGO-ABD-000-SP systems.
Can the MLX90365KGO-ABD-000-SP be programmed in-system?
Yes, the MLX90365KGO-ABD-000-SP supports full in-system programming of its EEPROM via the SENT or PWM interface using Melexis' standard PG-FI programming toolset. End-user programmable items include output mode, transfer characteristic (4- or 17-point), clamping thresholds, filter settings, and diagnostic configuration - all retained after power cycling and validated across temperature for MLX90365KGO-ABD-000-SP deployment.
