New LX4580 is a Highly Integrated 24-Channel Mixed-Signal IC for Aviation Systems

Microchip Technology announces the LX4580, a 24‑channel mixed‑signal IC designed to streamline high‑reliability actuation control systems for aviation. The LX4580 is highly integrated and replaces multiple discrete components with a single device that supports synchronized data acquisition, fault monitoring and motor control—reducing system size, weight and complexity.

The LX4580 is offered in a compact 144‑pin LQFP package and developed for applications including More Electric Aircraft (MEA), drones etc. The LX4580 integrates pressure sensing, temperature measurement, PWM motor drive outputs, current sensing, Hall effect sensor inputs, dual LVDT/resolver interfaces and dual high‑speed SAR ADCs. This level of integration delivers broad sensor coverage, precise timing alignment and improved reliability compared to multi‑device architectures.

The device’s redundant architecture is tailored for mission‑critical environments that demand fault tolerance and deterministic performance. By consolidating functions commonly spread across MCUs, ADCs, DACs, driver ICs and regulators, the LX4580 reduces board space and wiring complexity, supporting manufacturers’ goals to minimize overall system weight while meeting demanding safety and certification requirements (more info).
