Data Sheet January 3, 2006 FN9212.1
Li-ion/Li-Polymer Battery Charger Accepting Two Power Sources
The ISL6299A is a fully integrated low-cost single-cell Li-ion or Li-polymer battery charger. The charger accepts two power inputs, normally one from a USB (Universal Serial Bus) port and the other from a desktop cradle. The ISL6299A is an ideal charger for smart handheld devices that need to communicate with a personal computer via USB. The ISL6299A features 28V and 7V maximum voltages for the cradle and the USB inputs respectively. Due to the 28V rating for the cradle input, low-cost, large output tolerance adapters can be used safely. When both inputs are powered, the cradle input is used to charge the battery.
