Li-ion/Li-Polymer Battery Charger Accepting Two Power Sources
The ISL9214 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 ISL9214 is an ideal charger for smart handheld devices that need to communicate with a personal computer via USB. The ISL9214 features 28V maximum voltages for both the cradle and the USB inputs. Due to the 28V rated inputs, lowcost, large output tolerance adapters can be used safely. When both inputs are powered, the cradle input is used to charge the battery. The charge current is programmable for the cradle input with a small resistor. The end-of-charge current is also programmable by another external resistor. The charger incorporates ThermaguardTM which protects the IC against over temperature. If the die temperature rises above a typical value of +12
