  • Power source selection
    Publication number: 20060132086
    Abstract: A power source selection approach of one embodiment includes a voltage monitor to monitor a system supply voltage and to assert a droop signal if the system supply voltage droops below a threshold voltage. A power source selector is responsive to assertion of the droop signal to configure at least one power source, such as, for example, a battery pack, to attempt to provide sufficient voltage such that a system supply voltage is raised above the threshold voltage.
