Abstract
Provided is an apparatus for controlling multiple powers which is capable of turning on and off the multiple powers in their priorities for systems or components to be supplied with the multiple powers such as a liquid crystal display (LCD) module. In the apparatus for controlling multiple powers, an on-signal of high level is applied to an input terminal, and an output of a control signal generating unit is sequentially changed to a high level whenever a clock is applied to a clock signal input terminal by one period, so that outputs of the multiple powers are sequentially output. In addition, an off signal of low level is applied to the input terminal, and an output of the control signal generating unit is changed to a low level in a reversal order whenever a clock is applied to the clock signal input terminal by one period, so that outputs of the multiple powers are interrupted in the reversal order.
