<p><P>PROBLEM TO BE SOLVED: To provide an integrated power supply controller, obtained at a low cost further with operations capable together with many different power sources. <P>SOLUTION: By connecting adequate number of interfacing circuits 92,100,112 to a single input pin 48, the power source 10 is programmed for increasing the power and specific operation between toggles of on/off switches 96,108. In one operating mode, a light-emitting diode 106 of the interface circuit 100 is optically coupled to a microprocessor to inform the closing of the on/off switch 108, so as to make the microprocessor capable of controlling the power source 10 through an optical coupler 102. In another operating mode, the single on/off switch 96 controls the power source 10. In still another operating mode, a Zener diode 118 of the interfacing circuit 112 controls the power source 10 between brown-out state and black-out state. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
