by a single device responsible for synchronized data acquisition, fault monitoring and motor control, thus reducing the size, weight and complexity of the system.
The LX4580 is supplied in a compact 144-pin LQFP package and has been developed for applications such as More Electric Aircraft (MEA), guided defense systems, drones, and launch platforms. The LX4580 integrates pressure sensing, temperature measurement, PWM motor drive outputs, current sensing, Hall effect sensor inputs, dual LVDT/resolver interfaces, and high-speed SAR A/D converters. This level of integration provides broad sensor coverage, precise timing, and improved reliability compared to multi-device architectures.
“The LX4580 achieves an exceptional level of functionality in a single device, enabling our customers to simplify designs that previously required multiple integrated circuits,” said Ronan Dillion, director of Microchip’s High Reliability and RF business unit. “By reducing system complexity and providing robust evaluation tools, we are making development easier for engineers and delivering the next generation of reliable drive systems.”.
The device's redundant architecture is tailored for mission-critical environments that demand fault tolerance and deterministic performance. By integrating functions typically distributed among microcontrollers, A/D and D/A converters, drivers, and regulators, the LX4580 occupies less board space and simplifies connections, thus helping manufacturers achieve their goals of minimizing overall system weight while meeting stringent safety and certification requirements.
Microchip offers application documentation demonstrating its use with microcontrollers to accelerate customer development. These resources enable independent evaluation or rapid integration into customer control architectures, simplifying early design phases and helping teams efficiently meet regulatory documentation requirements.

Development Tools:
The available LX4580-EVB evaluation board and User Guide help customers simplify system development and evaluate the integrated circuit's features. The evaluation board incorporates an interconnect module that allows access to the SPI buses and integrated circuit functions for evaluating system performance.
Another User Guide that describes a control system using a linear actuator based on a Microchip SAMV71 microcontroller and an LX4580. The microcontroller manages the motor control loop and generates the motor control signals, while the LX4580 manages the main sensors.
