Portable Devices Need High-Performance Battery Chargers


Abstract:Three techniques for charging lithium-ion (Li+) batteries are described. Linear, switch-mode, and constant-current pulse
circuits are shown for each charging method.


Introduction
The proliferation of portable devices in recent years has underlined the need for small, efficient batteries and battery chargers.
Great advances in battery technology have resulted, with lithium-ion (Li+) and lithium-polymer now among the more popular battery
chemistries. To get the most performance from such batteries, designers have focused on the bat
