The power state of a device encapsulates what that devices’ power budget is, and what it is currently doing with this power. It is often internally represented by one or more finite-state machine abstractions. Use this tag for related questions about e.g. USB and USB Power Delivery, bus systems like I2C, power adapter firmware and signaling, and others in which there is a graph representation of the states (or modes) of a given device or implementation.
