ABSTRACT:
An integrated circuit for power management adapted to be used with a monitor which comprises a signal discriminator storing two reference values therein for being put in comparison with an input signal and generating an output signal according to the comparison, a clock generator adapted to be electrically connected to an oscillating circuit generating an oscillating signal, receiving and processing said oscillating signal to provide a clock input for the integrated circuit for power management, and a decoder decoding the output signal to enable the monitor in a desired operation state. The present integrated circuit for power management can not only prolong the lifetime of a cathode-ray tube but can also economize power consumption in consideration of environmental protection and economy. In addition, the present integrated circuit is more space-saving and cost-effective than a conventional device for economizing power consumption.
