a Highly Integrated 24‑Channel Mixed‑Signal IC
New LX4580, a 24-channel mixed-signal IC designed to streamline high-reliability actuation control systems for aviation and defence applications, from Microchip Technology
The LX4580 is highly integrated, replacing discrete components with a single device that supports synchronised data acquisition, fault monitoring, and motor control, reducing system size, weight, and complexity.
The LX4580 is provided in a compact 144-pin LQFP package and developed for applications including More Electric Aircraft (MEA), guided defence 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
- Dual high-speed SAR ADCs
This level of integration provides broad sensor coverage, precise timing alignment, and enhanced reliability compared to multi-device architectures.
Ronan Dillion, director of Microchip’s high-reliability and RF business unit, said, “The LX4580 brings together an exceptional level of functionality in a single device, allowing our customers to simplify designs that previously required multiple ICs. 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.”
The device’s redundant architecture is tailored for mission-critical environments that require fault tolerance and deterministic performance. By consolidating functions commonly spread across MCUs, ADCs, DACs, driver ICs and regulators, the LX4580 decreases board space and wiring complexity, supporting manufacturers’ goals to reduce overall system weight while meeting safety and certification requirements.
