Abstract
Accordingly, a smart switch device is described herein. In one embodiment, the device includes a first supply circuit configured to provide, based on a first supply voltage, an first voltage at a first output node; a second supply circuit configured to provide, based on a second supply voltage, a second voltage at a second output node; and a power management unit configured to provide a third voltage at a third output node based on both, the first supply voltage and the second supply voltage. The first, the second, and the third output nodes are coupled to a buffer capacitor. The device further includes a wakeup circuit configured to detect a wakeup event and further configured to enable the power management unit upon detecting a wakeup event.
