Abstract
Voltage surge is prevented when the output from a driver of a driving circuit performs a hard shutdown. In this manner, the elements in the driving circuit are prevented from being damaged by the voltage surge. A driving circuit includes a level shift circuit configured to convert an input signal from a preceding-stage circuit into an output signal having a higher voltage than the input signal, and a controller configured to determine whether a switch element is to perform a soft shutdown based on a state signal indicating a state of the preceding-stage circuit. Here, the driving circuit is configured to drive the switch element.
