<P>PROBLEM TO BE SOLVED: To provide an inexpensive load driving circuit which suppresses a resonance current flowing by bounce of an electric contact, and reduces a transition quantity of the electric contact. <P>SOLUTION: In the load driving circuit which supplies power to a load 1 from power supply through the electric contact 2b of a relay 2, the load driving circuit includes a power supply means 5 to supply the power to the load 1 from the power supply not through the electric contact 2b, during a bounce time when the electric contact 2b is turned on. <P>COPYRIGHT: (C)2008,JPO&INPIT |
