Abstract
Methods and apparatus are disclosed for controlling power distribution during transitory power-up period of multi-domain electronic circuits that are supplied by multiple power supplies. The power distribution is controlled by self-regulating power control circuits that operate based on power-up sequencing requirements. Described embodiments of the invention illustrate examples of power-switch and power-switch controller circuits used as elements of the power control circuitry.
