1. A driving circuit comprising:
- a level shift circuit configured to convert an input signal from a preceding-stage circuit into a signal having a higher voltage than the input signal; and
a controller configured to output a signal to allow a first switch element to perform a soft shutdown based on an output signal from the level shift circuit, whereinthe driving circuit is configured to drive the first switch element.

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.
