摘要：
A voltage detection circuit 1A comprises a coil 5 connected between positive and negative terminals of a battery 3 through input terminals T1 and T2, and an MR device RM magnetically coupled to the coil 5. Employing such a structure makes it possible to detect the voltage of the battery 3 in real time according to a change of magnetic resistance in the MR device RM.
