Product details
Overview
MLX90365EGO-ACD-000-RE from Melexis is an AEC-Q100 qualified Triaxis® Hall-effect absolute rotary and linear 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 integrated diagnostics for automotive pedal, throttle, and steering applications.
For engineers reviewing the MLX90365EGO-ACD-000-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (TSSOP-16), confirmed dual-die redundancy, real-world diagnostic behavior, magnetic field sensitivity (70 mT XY, 126 mT Z), and functional alternatives with documented output mode and thermal performance differences.
Technical Context
The MLX90365EGO-ACD-000-RE implements a 16-bit RISC microcontroller-based DSP that computes absolute angle from orthogonal BX/BY and parallel BZ magnetic field components using CoRDiC transformation. Its dual-die TSSOP-16 configuration provides full hardware redundancy with isolated diagnostic bands between dice.
It supports programmable piecewise-linear transfer characteristics across up to 17 points, selectable ratiometric analog or PWM output (100–1000 Hz), and on-chip EEPROM storage of calibration data, ID, and user-defined clamping thresholds - all operating across −40°C to +150°C with overvoltage (24 V) and ESD protection.
Key Specifications

|---|---|
| Output Modes | Ratiometric analog (0–100% VDD) or programmable PWM (100–1000 Hz); enables drop-in replacement of potentiometers or digital feedback loops. |
| Angular Accuracy | ±0.3° at 25°C (XY axis), enabling high-fidelity throttle or steering wheel position sensing without external calibration. |
| Magnetic Sensitivity | 70 mT (XY), 126 mT (BZ); supports compact magnet designs with IMC® gain tuning (k = 1–1.5) for robust field alignment. |
| Resolution | 12-bit DAC (analog), 12-bit PWM; delivers 0.025% duty-cycle LSB granularity for precise closed-loop control. |
| Supply Range | 4.5–5.5 V nominal; includes MT4V startup detection (3.8–4.2 V) and PTC entry at 5.8–6.6 V for system-level brown-out management. |
| Diagnostic Coverage | Open/short, broken VDD/VSS, field strength, and PWM integrity checks with dedicated diagnostic output levels (e.g., BVSSPD ≥ 95% VDD). |
| Operating Temperature | −40°C to +150°C (Grade L); validated per AEC-Q100 Rev G for under-hood and transmission-mounted applications. |
Pinout & Package
TSSOP-16 package with dual-die architecture for functional safety compliance; RoHS-compliant, 4.4 mm × 5.0 mm footprint, 1.2 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDIG1 | Digital supply for Die 1; decoupling required to suppress switching noise coupling into analog front-end. |
| 2 | VSS1 | Ground reference for Die 1; must be connected to system ground with low-inductance path for EMC stability. |
| 3 | VDD1 | Analog supply for Die 1; separate from VDIG1 to isolate power domains and reduce supply-induced error. |
| 4 | Test 01 | Factory test pin; not connected in end application; recommended to tie to VSS1 for EMC integrity. |
| 5 | Test 22 | Factory test pin; unused in operation; connect to VSS1 to minimize parasitic coupling. |
| 6 | OUT2 | Redundant output from Die 2; enables comparison with OUT1 for ASIL-B/C fault detection in safety-critical 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 prevents cross-die ground bounce. |
| 9 | VDIG2 | Digital supply for Die 2; isolated from VDIG1 to avoid single-point failure propagation. |
| 10 | VDD2 | Analog supply for Die 2; fully independent of Die 1 supplies to support dual-channel redundancy. |
| 11 | Test 02 | Factory test pin; tie to VSS2 to maintain signal integrity and reduce radiated emissions. |
| 12 | Test 21 | Factory test pin; connect to VSS2 to eliminate unintended antenna effects. |
| 13 | Not Used1 | No internal bond; must be grounded to avoid capacitive coupling into sensitive analog paths. |
| 14 | OUT1 | Main output from Die 1; drives external load (RL ≥ 1 kΩ for PWM, RL ≥ 4.7 kΩ for analog) with clamped saturation limits. |
| 15 | Test 11 | Factory test pin; tie to VSS2 to ensure stable reference during production testing and field operation. |
| 16 | Test 12 | Factory test pin; grounding ensures consistent startup behavior and avoids false diagnostic triggers. |

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-ACD-000-RE | Same die, −40°C to +125°C grade; lower thermal offset drift (±60 LSB15 vs ±90 LSB15) and no thermal correction firmware. | Suitable for under-dash modules but not transmission or turbocharger mounting locations. | Select when ambient temperature stays below 125°C and cost optimization is prioritized over extended thermal stability. |
| MLX90365LGO-ACE-000-RE | Same package and temperature grade, but includes factory-enabled thermal offset correction (AxE version) and preprogrammed 4-pt LNR curve. | Reduces calibration time in production; eliminates need for end-user programming of CLAMP_HIGH/LOW parameters. | Choose for high-volume automotive programs requiring guaranteed <±0.5° total angular error without field calibration. |
Compared with MLX90365EGO-ACD-000-RE, the KGO variant trades extended temperature capability for lower unit cost and reduced thermal drift, while the LGO-ACE offers plug-and-play accuracy at higher BOM cost - enabling selection based on thermal envelope, calibration infrastructure, and ASIL target.

FAQ
What is the operating temperature range of the MLX90365EGO-ACD-000-RE?
The MLX90365EGO-ACD-000-RE is rated for −40°C to +150°C ambient operation (Grade L), validated per AEC-Q100 Rev G. This enables deployment in high-temperature zones such as engine compartments, transmissions, and brake actuators where conventional sensors fail. The device maintains specified accuracy and diagnostic functionality across this full range due to on-chip thermal offset correction and robust packaging.
Does the MLX90365EGO-ACD-000-RE support both analog and PWM outputs simultaneously?
No, the MLX90365EGO-ACD-000-RE supports only one active output mode at a time - either ratiometric analog (0–100% VDD) or programmable PWM (100–1000 Hz) - selected via EEPROM configuration during programming. Both modes share the same OUT1/OUT2 pins but cannot operate concurrently; switching requires reprogramming and power cycle. This design prevents signal contention and ensures deterministic timing behavior in safety-critical systems.
How does the dual-die architecture of the MLX90365EGO-ACD-000-RE improve functional safety?
The MLX90365EGO-ACD-000-RE integrates two independent sensor dies in one TSSOP-16 package, each with its own analog front-end, DSP, memory, and output stage. This enables cross-die comparison of OUT1 and OUT2 signals to detect latent faults such as magnetic field misalignment, ASIC logic errors, or supply rail corruption - satisfying ISO 26262 ASIL-B requirements without external redundancy components. Diagnostic band isolation (>4 MΩ inter-die resistance) ensures fault containment.
Can the MLX90365EGO-ACD-000-RE be used with standard ferrite magnets?
Yes, the MLX90365EGO-ACD-000-RE operates reliably with standard N35–N52 neodymium or ferrite magnets. Its Triaxis® architecture requires only a rotating or linearly moving magnet with sufficient field strength: ≥70 mT in XY plane and ≥126 mT in Z direction. Ferrite magnets meeting these thresholds (e.g., 10 mm × 5 mm × 2 mm grade Y30) deliver full 12-bit resolution and <±1° total error when paired with the integrated IMC® structure and proper mechanical air-gap control.
What diagnostic functions are implemented in the MLX90365EGO-ACD-000-RE?
The MLX90365EGO-ACD-000-RE implements six diagnostic categories: open/short circuit detection on OUT1/OUT2, broken VDD/VSS supply monitoring (BVDDPD, BVSSPU), magnetic field strength validation, PWM integrity checking, thermal overload flagging, and internal EEPROM checksum verification. Diagnostic status is reported via dedicated output levels (e.g., Dsat_lo ≤ 2% VDD for active fault) and can be read back via the diagnostic pin or inferred from output anomalies - all configurable via EEPROM.
