Li-ion/Li Polymer Battery Charger Accepting Two Power Sources
ISL6293 Product details
Features
28V and 7V maximum voltages for the cradle and the USB inputs respectively. The 28V rating allows low-cost adapters be safely used. When both inputs are powered, the cradle input is used to charge the battery. The charge current is independently programmable for both inputs with two small resistors. One additional USBP pin allows the selection of high-power or low-power port for the U.
