Product Summary
The ISL6299AIRZ-T is a fully integrated low-cost single-cell Li-ionor Li-polymer battery charger. The charger accepts twopower inputs, normally one from a USB (Universal SerialBus) port and the other from a desktop cradle. TheISL6299A is an ideal charger for smart handheld devicesthat need to communicate with a personal computer viaUSB.
