SEMICONDUCTOR DEVICE

摘要

A semiconductor device presented herein includes a first wiring including a first end and a second end configured to receive a voltage lower than a voltage of the first end. The semiconductor device includes a second wiring including a third end connected to the first end, and a fourth end connected to the second end. The semiconductor device includes a switching element set on the first wiring, a capacitor set on the second wiring, and a fuse portion set on the second wiring and positioned on a third end side of the capacitor. The semiconductor device includes a potential sensing portion connected to the second wiring between the fuse portion and the capacitor and configured to sense a potential of a connection point thereof.

1. A semiconductor device, comprising:
a first wiring including a first end and a second end configured to receive a voltage lower than a voltage of the first end; a second wiring including a third end connected to the first end, and a fourth end connected to the second end; a switching element set on the first wiring; a capacitor set on the second wiring; a fuse portion set on the second wiring and positioned on a third end side of the capacitor; a potential sensing portion connected to the second wiring between the fuse portion and the capacitor and configured to sense a potential of a connection point thereof; and a control device configued to reduce a current flowing through the switching element and make the reduced current flow through the switching element when the second wiring is determined, from the potential sensed by the potential sensing portion, to have broken off.
