| 20090278590 | POWER SEQUENCE CONTROL CIRCUIT, AND GATE DRIVER AND LCD PANEL HAVING THE SAME - A power sequence control circuit receives an input positive voltage and an input negative voltage. The control circuit includes a pull-up stage, having a first terminal receiving the input positive voltage, a second terminal coupled to a node, and a control terminal receiving feedback of an output positive voltage. A pull-down stage has a first terminal coupled to the node and a second terminal coupled to an output negative voltage. A current-limit switching unit has a first terminal receiving the input positive voltage, a second terminal outputting the output positive voltage, and a control terminal coupled to the node. When the output negative voltage decreases, and if the pull-down stage decreases a control voltage at the node and the control voltage is less than a threshold value, the current-limit switching unit is conducted to transmit the input positive voltage as the output positive voltage. | 11-12-2009 |
