Current switch driving circuit arrangements

摘要

This current switch driving circuit arrangement particularly for, but not necessarily limited to, inductive device current switching, comprises a pair of output transistors constituting a driving transistor for turning ON a subsequent switching transistor and a current sinking transistor for turning OFF that switching transistor. A receiver circuit is arranged for applying one bilevel logical signal for alternatively driving the two transistors by way of intermediate circuits each having current multiplying circuitry for deriving the necessary driving currents. The intermediate circuitry is effective for toggling the current from one of the transistors to the other with provisions for insuring speedy switching action.
