ABSTRACT:
An output circuit for driving a power stage includes circuitry for diverting displacement currents due to parasitic capacitance when power is first applied to the circuit. When power is first applied, a current sinking transistor turns on to divert such displacement current away from the power stage input. A switching transistor subsequently renders the current sinking transistor non-conductive to permit normal operation.
