Product details
Overview
MLX90365LGO-ACD-000-RE from Melexis is an AEC-Q100 qualified Triaxis® Hall-based absolute rotary and linear position sensor IC in TSSOP-16 package, delivering 12-bit analog or PWM output with ±0.3° magnetic angle phase error (XY axis), 12-bit resolution, and automotive-grade operation from −40 °C to +150 °C - used in throttle, steering wheel, and pedal position sensing.
For engineers reviewing the MLX90365LGO-ACD-000-RE datasheet, pinout, applications, or equivalent options, key selection criteria include dual-die redundancy for functional safety, programmable multi-point transfer characteristic, thermal offset correction capability, open/short diagnostics, and ratiometric analog compatibility with legacy potentiometer interfaces.
Technical Context
The MLX90365LGO-ACD-000-RE integrates a Triaxis® Hall front-end sensing BX, BY, and BZ field components, feeding a 16-bit RISC DSP that computes absolute angular or linear position via CoRDiC-based rectangular-to-polar conversion. Its dual-die TSSOP-16 implementation provides full hardware redundancy for ASIL-B/C applications.
It supports end-user programming of output mode (analog ratiometric or PWM), 4- or 17-point piecewise-linear transfer characteristics, clamping thresholds, filter settings (0–2), and diagnostic behavior - all stored in 128 B EEPROM with 48-bit unique ID. The output stage offers push-pull or open-drain configurations with built-in overvoltage protection up to +24 V and under-voltage detection at 3.8–4.2 V.

FAQ
What is the operating temperature range of the MLX90365LGO-ACD-000-RE?
The MLX90365LGO-ACD-000-RE is qualified for continuous operation from −40 °C to +150 °C, matching AEC-Q100 Grade 0 requirements. This rating applies to the full TSSOP-16 dual-die configuration and is validated across electrical, magnetic, and diagnostic parameters per datasheet revision 5.9. The MLX90365LGO-ACD-000-RE maintains specified accuracy and response time across this range, including thermal offset correction functionality.
Does the MLX90365LGO-ACD-000-RE support both analog and PWM output modes?
Yes, the MLX90365LGO-ACD-000-RE supports selectable output modes: ratiometric analog voltage (0.5–98.5% VDD) and programmable PWM (100–1000 Hz). Mode selection is configured via EEPROM programming during end-of-line calibration. Both outputs derive from the same Triaxis® sensor data path and retain 12-bit resolution, with PWM offering <±0.009% duty-cycle jitter at 1000 Hz per the MLX90365LGO-ACD-000-RE datasheet.
How does the dual-die architecture of the MLX90365LGO-ACD-000-RE improve functional safety?
The MLX90365LGO-ACD-000-RE implements two independent sensor dice in one TSSOP-16 package, each with separate analog front-end, DSP, memory, and output stage. This enables cross-comparison of OUT1 and OUT2 signals for fault detection without external circuitry, supporting ASIL-B/C decomposition per ISO 26262. Isolation resistance ≥4 MΩ between dice ensures failure containment, and the MLX90365LGO-ACD-000-RE's on-chip diagnostics cover open/short, VDD/VSS breaks, and magnetic field faults.
Can the MLX90365LGO-ACD-000-RE be programmed for custom transfer characteristics?
Yes, the MLX90365LGO-ACD-000-RE supports end-user programming of piecewise-linear transfer characteristics with either 4 or 17 user-defined points, stored in its 128 B EEPROM. This allows compensation for mechanical non-linearity in throttle linkages or steering gears without MCU intervention. Calibration is performed via Melexis' PTC software tool, and the MLX90365LGO-ACD-000-RE retains programmed values across power cycles and temperature extremes.
What diagnostic features are integrated into the MLX90365LGO-ACD-000-RE?
The MLX90365LGO-ACD-000-RE integrates open/short circuit detection on the output, broken VDD/VSS monitoring, field strength diagnostics, and PWM integrity checking. Diagnostic mode and level are programmable via EEPROM, and status is reported through dedicated diagnostic output pins or encoded in the main output signal. These capabilities are fully documented in section 14.7 of the MLX90365LGO-ACD-000-RE datasheet and require no external components to implement.
