摘要：
A circuit includes a power detector and a logic circuit. The power detector is configured to output a first power management signal according to a first power supply signal from a first power supply and a status signal. The circuit is configured to operate in different modes in response to the status signal. The logic circuit is configured to output a second power management signal, according to the first power management signal and the status signal.
