Control circuit for controlling devices to boot sequentially |
摘要 |
A control circuit for booting a number of devices in a certain order includes two delay circuits and three switch circuits, the first switch circuit and the first delay circuit receiving a power good signal and a voltage signal from a power supply unit and thus allowing a first device to boot and the first delay circuit outputting a first delay signal after a set time, to the second switch circuit and the second delay circuit, which repeat the process of the first delay circuit and switch circuit, to boot the remaining devices. |
