Abstract
Methods, systems, and devices are described for a power-on sequence for a circuit. A sequence generator for an electronic system may control various power domains to enter known states and prevent unwanted states as other domains of the system power-up. Regulator modules may be controlled to remain in an inoperable state until a reference voltage stabilizes at a predetermined reference level. The regulator modules regulate a received voltage supply to output a regulated voltage at the reference level, the regulated voltage set via a comparison to the reference voltage. Various analog and digital modules may be controlled to remain in an known state until the regulated voltage stabilizes at substantially the reference level. Additional sequencing is described for other dependencies, as well.
