Abstract: Embodiments provide apparatuses and systems in which slave power sequencers share a command bus and power sequence respective power groups through power sequence states of a power sequencing protocol in response to commands on the command bus. In some examples, a system may include a master power sequencer to output onto a command bus a command to perform a power sequencing protocol for transitioning the system from a first power state to a second power state, and a plurality of slave power sequencers sharing the command bus, each slave power sequencer to power sequence a respective power group to a next power sequence state in response to the command. Other examples are described and claimed.
