Title: Circuit for Zeroing Level At Power Off In Multi System
Inventor: YOO YONG HWA
IPC: H04Q1/20
Filed: 2001-11-01
Abstract: PURPOSE: A circuit of zeroing a level during power off in a multi-layer system is provided to zero an output of a decoder by sensing that power of a corresponding layer is turned off, and to nearly zero a power level on boards of the powered-off layer, thereby preventing the boards from being damaged by a surge generated while inputting/outputting the boards. CONSTITUTION: When power of the second layer is turned off, an FET zeroes power of a decoder(314) by sensing the powered-off layer, and shorts power of an integrated circuit whose default state output is high, in order to prevent an output from being plus 5V. A comparator(315) senses that a power level of the second layer becomes plus 4.6V from the plus 5V. If the power level falls less than the plus 4.6V, an output end of the comparator(315) becomes high from low at first, in order to prevent a CPU from reading a state of the powered-off second layer or writing data, and maintains the power level of the second layer near to zero.
