摘要:
A semiconductor device includes: a first output transistor and a second output transistor configured to be connected between a first terminal and second terminal; an active clamp circuit configured to be connected to a first control terminal of the first output transistor to limit a terminal-to-terminal voltage appearing between the first and second terminals to a clamp voltage or less; a first variable resistive element provided between a node configured to be fed with a control signal and the first control terminal; a second variable resistive element provided between the node and a second control terminal of the second output transistor; and a turn-off circuit configured to be connected to a connection node between the second variable resistive element and the second control terminal so as to be able to turn the second output transistor off.
