  • Semiconductor device
    Patent number: 11689195
    Abstract: In general, according to one embodiment, a semiconductor device includes a first terminal, a second terminal and a first circuit. The first circuit includes a first switching element, a second switching element and a first resistor. The gate of the first switching element is coupled between the first node and the second terminal. The first resistor and the second switching element are coupled in series between the first node and the second terminal. The first circuit is configured to change the first switching element and the second switching element from an off state to an on state when supply of the first voltage to the first node is stopped.
