<p><P>PROBLEM TO BE SOLVED: To provide a voltage detection circuit capable of detecting a battery voltage in real time with a simple configuration. <P>SOLUTION: The voltage detection circuit 1A includes a coil 5 connected between positive-negative both terminals of the battery 3 through input terminals T1, T2, and an MR element R<SB>M</SB>bonded magnetically to the coil 5. By adopting such a configuration, the battery 3 voltage can be detected in real time based on a change of a magnetic resistance in the MR element R<SB>M</SB>. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
