<P>PROBLEM TO BE SOLVED: To materialize a connection target which makes a power feeder recognize connection without fail and prevents the malfunction due to a rush current. <P>SOLUTION: This rush current limiting circuit 10 suppresses a rush current supplied from a PC2 and makes the PC2 recognize that a device 3 is connected, by being provided with: a current limiting circuit 13 which limits the current from the PC2 so as to suppress the rush current; a time adjusting circuit 12 which cancels the limitation of the current by the current limiting circuit 13 when a specified time has passed after start of the supply of the current; and a recognition current generating circuit 11 which is provided at the previous stage of the current limiting circuit 13 and the time adjusting circuit 12, and generates a recognition current for making the PC2 recognize that a device 3 is connected to the PC2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
