PROBLEM TO BE SOLVED: To provide a load driving device that reduces current, for maintaining an FET in an on-state, more than before. SOLUTION: A source of an FET 11 is connected to battery voltage +V via a fuse 2, and an electrical load 1 is connected to a drain of the FET 11. A connection node between a capacitor 121 and a resistor 122 of a serial circuit 12 comprising the capacitor 121 and the resistor 122 is connected to a gate of the FET 11. An FET 14 is connected in series to the serial circuit 12. The source and drain of an FET 15 are connected to both ends of the capacitor 121. A connection node between a resistor 16 and a resistor 18 is connected to a gate of the FET 15. An FET 18 is connected to a resistor 17. COPYRIGHT: (C)2011,JPO&INPIT |
