Power supply for mobile devices
Michael Mueller of congatec considers what to look for when selecting a power supply for mobile devices.
the development of the application-specific computer with battery management and ACPI implementation.

From the device manufacturer’s perspective, batteries are just a sideshow. His focus, naturally, is on the application. But the success of a device depends to a large extent on an intelligent and optimized power supply. Battery cell technology is evolving. The trend is going towards more powerful battery packs that combine high voltage and large capacity, not unlike the power tool cells of a cordless screwdriver. The implementation of these new technologies, however, requires special know-how. A similar trend can be found in computer hardware where processors are becoming more complex, more powerful and more energy efficient. A powerful embedded PC is behind almost every application, but the complex design around the processor diverts development resources away from core business activities. Computer and battery are mandatory building blocks of the application, but they can be successfully delegated to the experts. New applications are conceivable thanks to these new technologies. Therefore, it’s worth consulting with the specialists from RRC and congatec. Their collaboration bundles their combined mobile embedded expertise, and together they are able to support the specific application of the customer. The Computer-on-Modules from congatec allow the device manufacturer to focus on the application-specific hardware and software, thereby greatly relieving in-house resources.

With the Mobility Starter Kit from congatec and RRC a laboratory set-up can quickly be done. The more detailed Integration Kit further provides all schematics, source files of the microcontroller program along with complete development documentation.

Thanks to the tried, tested and certified components the user avoids many learning curves. Faster time-to-market and a more economical design with optimized hardware are a sound foundation for a customer's success. A classic win-win situation.
