Converged Handhelds

consumer_b4_chh2Converged or “smart” handhelds integrate the wireless, voice and data capabilities of PDAs and mobile phones into a single device. But other convergent devices are already appearing that merge mobile phone-cameras with MP3 players and PDAs, and patient alert tools that bring together GPS trackers with personal or emergency alarms. When combined in one package, the power demands of these devices on the battery system is enormous.

CAP-XX supercapacitors can meet the power management challenges inherent in converged products. They provide the power to run extra features, extend battery run time and improve operation in low temperature environments, enable memory back up and hot-swapping capabilities, reduce excessive battery load to extend useful life, and can even replace tantalum capacitors to provide a lighter-weight, thinner device.
