ABSTRACT:
A driver circuit to limit the di/dt downgoing transition to a desired value employs an active feedback path. The driver circuit utilizes a Schottky Barrier Diode as a current bleed to limit the base current of the drive circuit transistor. The active feedback path includes a normally conductive transistor which turns off when the output falls to a predetermined level. Elimination of the active feedback path in this condition insures maximum DC drive.
