Battery-powered products such as personal media players, smart phones, portable gaming consoles and GPS navigation devices operate from USB ports and continually integrate new functions, transforming them into feature-rich products that drive the high-end CE market. This increase in functions requires higher-capacity batteries such as Li-ion/polymer cells to drive the feature content. The desire for small form factors, increased features, portability and flexibility, as well as the ability to charge batteries quickly and safely, present a number of challenges for the product design engineer.

Moreover, the need for high-efficiency charging, high levels of feature integration in the battery-charger IC, efficient use of board space, and increased product reliability exert considerable pressure on the design of battery-powered electronic devices. This technical article, written by Linear Technology's Product Marketing Engineer Steve Knoth, talks about integrating power-manager ICs in high-end handsets.
