摘要
Methods and apparatus for power management of embedded devices are provided. An example apparatus includes a primary power management integrated circuit (PMIC) to communicate with an embedded system to determine a power state. The example primary PMIC is to include a first power state sequence controller and a first power supply controller. The example first power state sequence controller is to drive a first power supply controller according to the power state. The example first power supply controller is to activate a first set of rails to apply power to the embedded system. The example apparatus includes a secondary PMIC including a second power state sequence controller and a second power supply controller. The example second power sequence controller is to drive a second power supply controller according to the power state. The example second power supply controller is to activate a second set of rails to apply power to the embedded system.
