Abstract
An integrated circuit includes a global power supply node. A first power domain has a first power management circuit, which includes a local power supply node. A first power control circuit is capable of receiving an input signal. A second power control circuit has a higher current capacity than the first power control circuit. The first power control circuit and the second power control circuit are coupled to the local power supply node and the global power supply node. The input signal is configured to initiate a power sequence, e.g., a power up process or a power down process, in the first power control circuit. A first control signal generated by the first power control circuit is configured to initiate a power sequence in the second power control circuit.
