Abstract
A sequential voltage output circuit is connected between a power supply and a number of loads. The voltage sequence output circuit includes a complex programmable logic device (CPLD) and a number of switching circuits. When the CPLD receives a power on signal, the CPLD outputs a number of control signals sequentially through a number of outputs. When a switching circuit receives a control signal from the CPLD, the switching circuit allows the power supply to supply power to a corresponding load.
