<P>PROBLEM TO BE SOLVED: To provide a fuse control circuit whose circuit scale is made smaller than a conventional fuse control circuit, an illuminance sensor, a proximity sensor, a cellular phone, a digital still camera, and a power supply circuit. <P>SOLUTION: The fuse control circuit 1 includes an element 4 for separation, which disconnects a node B and a fuse melting detection circuit 3 when a fuse melting circuit 2 makes a current flow to a fuse element F1 and connects the node B and the fuse melting detection circuit 3 when the fuse melting circuit 2 does not make a current flow to the fuse element F1. <P>COPYRIGHT: (C)2011,JPO&INPIT |
