Abstract:
A drive control apparatus for a switching element drives a switching element including a sense element, and includes a drive circuit that provides a gate driving signal to the switching element, a transient characteristic absorbing circuit that absorbs a transient characteristic of the sense element when the switching element is turned on, and a determination circuit that determines an overcurrent or a short-circuit state of the switching element from an output of the sense element.
