Abstract

A drive device includes a driver configured to drive a high-side transistor and a low-side transistor; a first current detecting part for detecting one of an upper-side current that flows to the high-side transistor and a lower-side current that flows to the low-side transistor; a first current determining part that detects a sign of switching of a forward direction/reverse direction of the upper-side current or the lower-side current detected by the first current detecting part or the switching per se; and a slew rate adjusting part configured to control the driver such that a slew rate of the high-side transistor or the low-side transistor is adjusted according to a determination result of the first current determining part.
