Abstract:
A power management circuit for an electronic device sequentially activates and/or deactivates electronic circuits of the electronic device. The power management circuit provides a first group of one or more circuit power management signals to activate and/or deactivate a first electronic circuit from among the electronic circuits. Thereafter, the power management circuit provides a corresponding power management signal from among a second group of the one or more circuit power management signals that corresponds to a portion of the first electronic circuit that has been activated and/or deactivated by the first group of the one or more circuit power management signals to activate and/or deactivate a portion of a second electronic circuit from among the electronic circuits. The power management circuit continues to sequentially provide each of the one or more circuit power management signals in a similar manner until the electronic circuits of the electronic device have been activated and/or deactivated.
