Zusammenfassung:A dual rail device includes a first power domain circuit coupled to a first power supply through a first header control switch and a second power domain circuit coupled to a second power supply. The first and second power supplies have different steady-state voltage levels. The first power domain circuit is interfaced to the second power domain circuit. The device also includes a power detector circuit for providing a control signal for the first header control switch responsive to a voltage level of the second power supply.
