Li-ion/Li Polymer Battery Charger Accepting Two Power Sources

The ISL6293 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 another one from a desktop cradle. The ISL6293 is an ideal charger for smart handheld devices that need to communicate with a personal computer via USB
The ISL6293 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 USB input. The charger is self-protected against over temperature. If the die temperature rises above 100C, a thermal foldback function reduces the charge current automatically to prevent further temperature rise. The charger preconditions the battery with low current when the battery voltage is below 2.6V. The charger has two indication pins. The PPR (power present) pin outputs an open-drain Logic LOW when either the cradle or the USB input power is attached. The CHG (charge) pin is also an open-drain output that indicates a Logic LOW when the charge current is above a minimum current level. When the charge current is below the minimum current, the charger remains in operation but the CHG pin indicates a Logic HIGH signal. For simplicity, the charger does not have re-charge or Timer functions.
