Microchip Technology has introduced the LX4580, a highly integrated 24-channel mixed-signal integrated circuit (IC) engineered to simplify high-reliability actuation control systems used in aviation and defense environments. The new device consolidates several discrete components into a single solution capable of synchronized data acquisition, motor control and fault monitoring-helping manufacturers reduce system size, weight and design complexity.
Packaged in a compact 144-pin LQFP, the LX4580 is built for demanding applications such as More Electric Aircraft (MEA), guided defense systems, unmanned aerial vehicles (UAVs), drones and launch platforms. The IC integrates multiple sensing and control capabilities, including pressure and temperature measurement, PWM motor drive outputs, current sensing, Hall-effect sensor inputs, dual LVDT/resolver interfaces and dual high-speed SAR ADCs.
By combining these features in one platform, the LX4580 provides extensive sensor support, precise timing synchronization and enhanced reliability compared with traditional multi-chip architectures commonly used in aerospace and defense control systems.
“The LX4580 brings together an exceptional level of functionality in a single device, allowing our customers to simplify designs that previously required multiple ICs,” said Ronan Dillion, director of Microchip’s high-reliability and RF business unit. “By reducing system complexity and providing robust evaluation tools, we’re making it easier for engineers to accelerate development and deliver the next generation of reliable actuation systems.”

Built for Mission-Critical Environments
The LX4580 has a redundant architecture, which is ideal for mission-critical applications where fault tolerance and deterministic system operation are of utmost importance. The LX4580 reduces board space and wiring complexity by integrating functions that are usually distributed among microcontrollers, analog-to-digital converters, digital-to-analog converters, driver ICs, and voltage regulators.
The LX4580 also helps aerospace manufacturers in their ongoing quest for weight reduction in overall systems, as well as safety, reliability, and certification requirements for aviation and defense platforms.
Development Resources for Faster Integration
To assist engineers in accelerating the development process, Microchip offers a wide range of application documentation and development tools that show the possibilities of using the LX4580 alongside its portfolio of microcontrollers.
The tools are also designed to help with the validation process in the initial phase of the design and assist engineers in addressing the documentation needs of the certification process, which is critical in the aerospace and defense industry.
