<P>PROBLEM TO BE SOLVED: To improve sensitivity of a current sensor. <P>SOLUTION: A current sensor 10 for an integrated circuit comprises: a lead frame 12 having at least two leads coupled to form a conductor portion 14; and a substrate 16 having a first surface on which one or a plurality of magnetic field transducers 18 are disposed. The first surface is proximate to the conductor portion and a second surface is distant from the conductor portion. The substrate is disposed so as to have the first surface of the substrate 16 above the conductor portion and the second surface of the substrate 16 above the first surface. The substrate is oppositely oriented in the integrated circuit, relative to a conventional orientation. With this arrangement, the current sensor is provided with the one or the plurality of magnetic field transducers, proximate to the conductor portion. <P>COPYRIGHT: (C)2013,JPO&INPIT |
