Technical Context
The MLX90365EGO-ABB-000-TU integrates a Triaxis® Hall front-end sensing BX, BY, and BZ magnetic field components, enabling absolute rotary (0–360°) or linear position decoding via on-chip DSP and CoRDiC coordinate rotation. Its dual-die TSSOP-16 architecture provides full hardware redundancy for ASIL-B–capable systems.
It supports programmable multi-point piecewise-linear transfer characteristics, selectable ratiometric analog or PWM output modes, and embedded diagnostics including open/short detection, over-voltage protection, under-voltage monitoring, and broken-track detection across both dies - all operating across −40°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V nominal; supports robust operation in noisy automotive 12 V systems with ±24 V absolute max rating. |
| Output Resolution | 12-bit (4096 steps); enables sub-degree angular resolution (e.g., 0.087°/LSB at 360° range) for high-fidelity position feedback. |
| Angular Accuracy | ±0.3° at 25°C (XY axis); critical for closed-loop control in throttle and steering applications requiring tight linearity. |
| Operating Temperature | −40°C to +150°C; qualified per AEC-Q100 Grade 0, enabling direct placement near powertrain or chassis hot zones. |
| PWM Frequency Range | 100–1000 Hz; configurable for EMI-optimized timing in safety-critical subsystems without external clocking. |

| Diagnostics Coverage | Open/short, over-voltage, under-voltage, broken VDD/VSS, and field strength monitoring - all with dedicated diagnostic output signaling. |
Pinout & Package
TSSOP-16 package with dual-die redundancy; RoHS compliant, 4.4 mm × 5.0 mm footprint, 1.2 mm height, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDIG1 | Digital supply for Die 1; decoupling required to suppress switching noise affecting PWM/analog integrity. |
| 2 | VSS1 | Ground reference for Die 1; must be low-impedance and separated from analog ground per EMC best practice. |
| 3 | VDD1 | Power supply for Die 1; tied internally to VDIG1 but routed separately for redundancy verification. |
| 4 | Test 01 | Factory test pin; not connected in end application; recommended to tie to VSS1 for EMC stability. |
| 5 | Test 22 | Factory test pin; unused in production; connect to VSS1 to minimize radiated emissions. |
| 6 | OUT2 | Redundant output from Die 2; matches OUT1 function (analog/PWM) for cross-checking in safety architectures. |
| 7 | Not Used | No internal connection; must be grounded to prevent floating node coupling and ensure EMC compliance. |
| 8 | Test 12 | Factory test pin; no user function; tie to VSS1 to avoid parasitic antenna effects. |
| 9 | VDIG2 | Digital supply for Die 2; independent rail enables fault isolation between redundant signal chains. |
| 10 | VSS2 | Ground for Die 2; physically isolated from VSS1 to support dual-rail diagnostic independence. |
| 11 | VDD2 | Power for Die 2; electrically separate from VDD1 to sustain operation during single-rail failure. |
| 12 | Test 02 | Factory test pin; no end-user use; grounding prevents capacitive coupling into sensitive analog paths. |
| 13 | Test 21 | Factory test pin; tie to VSS2 to maintain symmetry and reduce differential-mode EMI. |
| 14 | Not Used | Unbonded pad; must be grounded to avoid resonance and ensure mechanical stability during reflow. |
| 15 | OUT1 | Main output (analog ratiometric or PWM); drives external ADC or microcontroller input with 12-bit fidelity. |
| 16 | Test 11 | Factory test pin; connect to VSS2 to complete symmetric grounding scheme and meet ISO 11452-4 requirements. |

FAQ
What is the operating temperature range of the MLX90365EGO-ABB-000-TU?
The MLX90365EGO-ABB-000-TU operates from −40°C to +150°C and is AEC-Q100 qualified for Grade 0 automotive applications. This wide range enables direct mounting on engine manifolds, transmission housings, or brake calipers without external thermal shielding, and its on-chip thermal offset correction maintains angular accuracy within ±0.5° across the full span.
Does the MLX90365EGO-ABB-000-TU support both analog and PWM output simultaneously?
No - the MLX90365EGO-ABB-000-TU supports either ratiometric analog output or PWM output, selected via end-user programming (OUT mode parameter). Both modes deliver 12-bit effective resolution, but only one is active at a time; switching requires reprogramming the EEPROM configuration, not runtime toggling.
How does the dual-die architecture in the MLX90365EGO-ABB-000-TU improve functional safety?
The MLX90365EGO-ABB-000-TU integrates two fully independent sensor dies in one TSSOP-16 package, each with separate VDD/VSS/VDIG rails and dedicated OUT1/OUT2 outputs. This enables cross-comparison of position values in ASIL-B systems, detecting single-point failures such as die malfunction, bond wire break, or magnetic interference - without requiring duplicate PCB layouts or connectors.
Can the MLX90365EGO-ABB-000-TU be used with standard ferrite magnets?
The MLX90365EGO-ABB-000-TU is optimized for use with NdFeB or SmCo magnets due to its 70 mT BX/BY and 126 mT BZ sensitivity thresholds. Standard ferrite magnets typically produce <30 mT fields at practical air gaps and will not reliably saturate the Triaxis® front-end; performance degrades significantly below 20 mT magnetic flux norm, as specified in the datasheet.
What diagnostic features are implemented in the MLX90365EGO-ABB-000-TU?
The MLX90365EGO-ABB-000-TU implements open/short circuit detection on the output stage, over-voltage protection (up to +24 V), under-voltage lockout (MT4V threshold), broken VDD/VSS detection, field strength monitoring, and programmable diagnostic output signaling. All diagnostics operate independently per die and can be configured via EEPROM settings without external components.
