Abstract:
1. A power control device, comprising: a substrate; a first switch that is formed in the substrate to selectively couple a first signal line to a first lead of a first capacitor that is coupled to a first rail of a power distribution system of the substrate; and a switch control that is formed in the substrate and is associated with the first switch, the switch control to couple the first signal line to the first lead of the first capacitor in response to a determination that a second signal line transitions from a logical low state to a logical high state while the first signal line is in the logical high state, to decouple the first signal line from the first lead of the capacitor in response to a determination that the second signal line transitions from the logical high state to the logical low state while the first signal line is in the logical high state; wherein the first capacitor supplies power to an inter-integrated circuit slave when the first switch decouples the first lead of the first capacitor from the first signal line.
