Abstract:
1. A sequencing control circuit, comprising: a chip being connected to a first voltage terminal, and a second voltage terminal through a node, a signal from the second voltage terminal being posterior to a signal from the first voltage terminal; a first control circuit, an output terminal of the first control circuit being connected to the chip through the node; a second control circuit, an input terminal of the second control circuit being connected to a signal terminal of an electronic component, an output terminal of the second control circuit being connected to the chip through the node; and a lagging voltage terminal being connected to an input terminal of the first control circuit for providing a signal posterior to the signal from the first voltage terminal; wherein when the lagging voltage terminal and the signal terminal of the electronic component both input a high level signal, the output terminals of the first control circuit and the second control circuit both output a high level signal, thereby ensuring that the signal from the second voltage terminal is input to the chip posterior to the signal from the first voltage terminal being input to the chip; when the lagging voltage terminal input a low level signal or the signal terminal input a low level signal, the second voltage terminal will be connected to ground.
