Abstract
A transistor circuit includes a transistor having a control electrode, a first current electrode, and a second current electrode. A turn off mode change circuit has a signal input that receives a series of pulses, an output coupled to the control electrode of the transistor, and a control input. The turn off mode change circuit has a fast turn off mode and a slow turn off mode. A turn off mode detection circuit is coupled between the first current electrode and the second current electrode. The turn off mode change circuit detects when a transition from the fast turn off mode to the slow turn off mode is desired and when a transition from the slow turn off mode to the fast transition mode may be performed.
