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.
Claims22
An apparatus comprising:
- 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;
- and
- a power source selector responsive to assertion of the droop signal to configure at least one power source to attempt to provide sufficient voltage to raise a system supply voltage above the threshold voltage.
An apparatus comprising:
- a voltage monitor to monitor a voltage of a system supply rail and to assert a droop signal responsive to the voltage of the system supply rail drooping below a threshold voltage;
- and
- a battery pack selection module responsive to the droop signal to enable at least one battery pack.
A method comprising:
- detecting that a system supply voltage is below a threshold voltage;
- and
- responsive to the detection, configuring at least one power source to attempt to provide sufficient voltage to raise the system supply voltage above the threshold voltage.
A system comprising:
- a bus to communicate information;
- a processor coupled to the bus to process instructions;
- an antenna coupled to the bus to receive wireless data;
- and
- a power delivery sub-system coupled to the bus to provide power to the system, the power deliver sub-system including
- a voltage monitor to monitor a system rail voltage and to assert a droop signal if the system rail voltage drops below a threshold voltage;
- at least a first power source, the first power source comprising one of a battery pack, a fuel cell, a photovoltaic cell and an uninterruptible power supply;
- and
- a power source selector, the power source selector being responsive to the droop signal to enable the at least first power source.
