Abstract
An insulated gate device drive apparatus for driving an insulated gate device by using a charging current outputted from a totem-pole output circuit constituted by a high-side output transistor and a low-side output transistor. The insulated gate device drive apparatus includes a charging current correction circuit configured to perform correction to increase the charging current that is decreased by an increased voltage drop of high-side wiring resistance between a power supply and the high-side output transistor.
