PROBLEM TO BE SOLVED: To provide a loading circuit capable of optimumly controlling a load at high precision over a wide range, using a simplified configuration of a feedback means. SOLUTION: A microcomputer 15 variably controls individual on-time and off-time or on/off cycle of pulse drive signals S1 and S2 supplied to transistors 5 and 7, based on the monitoring result from a current detection circuit 13 which monitors state of a battery 14. Thus, the battery 14 is optimumly controlled with high precision in a wide range. Since the transistors 5 and 7 are controlled with the independent microcomputer 15, only a small mounting area is required as a feedback means. COPYRIGHT: (C)2005,JPO&NCIPI
