Abstract
A semiconductor device includes a semiconductor chip on which a semiconductor integrated circuit is formed, a plurality of leads disposed around the semiconductor chip, chip-directed wires connecting leads to the semiconductor chip, and a package sealing those. The semiconductor integrated circuit senses a sensing target current flowing through a sense resistor based on the voltage drop across the sense resistor, and performs predetermined operation based on the sensing result. The plurality of leads include a first and a second lead connected to one end and the other end of the sense resistor. The sense resistor is formed using a sensing metal member connecting between the first and second leads within the package without passing via the semiconductor chip.
