Switch circuit, semiconductor device, and battery device |
摘要 |
There is provided a semiconductor device capable of preventing the passage of current that is unexpected in a circuit operation even in the case of reverse connection, thus ensuring higher safety. The semiconductor device has a switch circuit which includes: a first transistor; a second transistor having a drain thereof connected to a drain of the first transistor, a source and a back gate thereof connected to a back gate of the first transistor, and a gate thereof connected to a source of the first transistor; and a third transistor having a drain thereof connected to the source of the first transistor, a source and a back gate thereof connected to the back gate of the first transistor, and a gate thereof connected to the drain of the first transistor. |
