This IC integrates the build-in comparator for the voltage detection of the AC adapter, and selects the AC adapter or battery automatically for power supply to the system. Provides a wide range of power supply voltage, low standby current, and high efficiency, which makes them ideal as a built-in charging device in products such as notebook PC.
