ABSTRACT:
High side driver circuitry for a defibrillator circuit employs respective capacitors connected to respective gates of silicon controlled rectifiers serving as high side switches. Applying a voltage pulse to a selected capacitor turns on the associated SCR. Positive turn-on of the high side SCRs is insured by inserting a constant current source into the low side activation current path at start-up.
