An improved gate drive circuit is provided for a power device, such as a transistor. Tue gate driver circuit may in -clude: a current control circuit; a first secondary current source that is used to control the switching transient during turn off of the power transistor and a second secondary current source that is used to control the switching transient during turn on of the power transistor. In operation, the current control circuit operates, during turn on ofthe power transistor, to source a gate drive current to a control node ofthe power transistor and, during turn off ofthe power transistor, to sink a gate drive current from the control node of the power transistor. The first and second secondary current sources adjust the gate drive current to control the voltage or current rate of change and thereby the overshoot during the switching transient.
