Mixed-signal IC targets aerospace actuation systems
Microchip has introduced a highly integrated device aimed at simplifying actuation control in aerospace and defence platforms. The LX4580 brings multiple sensing, control and monitoring functions into a single component, reflecting a broader trend toward integration in mission-critical electronics.
For eeNews Europe readers, this development highlights how component-level integration could help reduce system complexity in safety-critical designs, particularly in applications such as More Electric Aircraft and autonomous defence systems.
Integration to reduce system complexity
The LX4580 is a 24-channel mixed-signal IC designed to replace multiple discrete components typically used in actuation systems. It combines functions such as pressure and temperature sensing, PWM motor drive outputs, current sensing and Hall effect inputs, alongside dual LVDT/resolver interfaces and high-speed SAR ADCs.
By consolidating these capabilities, the device potentially reduces board space, wiring and overall system weight. This could be particularly relevant in aerospace platforms, where size and weight constraints remain critical. The integration also supports synchronised data acquisition and timing alignment, which are key requirements in deterministic control systems.
The IC is housed in a 144-pin LQFP package and targets applications including drones, guided systems and launch platforms, alongside aircraft electrification programmes.
Redundancy for mission-critical environments
A central feature of the device is its redundant architecture, designed to meet fault tolerance requirements in safety-critical environments. By integrating functions typically spread across MCUs, ADCs, DACs and driver ICs, the LX4580 could simplify certification processes while supporting reliability targets.
“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.”
Microchip is also offering development support, including evaluation boards and application documentation demonstrating integration with its microcontrollers. These resources are intended to streamline early design phases and help engineers address regulatory requirements more efficiently.
