Abstract
Provided is a driving apparatus including a temperature detection circuit configured to output a temperature detection signal corresponding to a temperature of a switching device, a current detection circuit configured to sample, at a timing during an ON period of the switching device, a current detection signal corresponding to a current that flows in the switching device, and a driving circuit configured to adjust, according to the temperature detection signal and the current detection signal, a driving current to be supplied to a control terminal of the switching device. When the current detection signals are the same, the driving circuit may decrease the driving current according to the temperature detection signal indicating a lower temperature of the switching device. When the temperature detection signals are the same, the driving circuit may decrease the driving current according to the current detection signal indicating a smaller current regarding the main current.
