A circuit in an ignition system having a switchable current drive circuit responsive to a first control signal, and a charging circuit responsive to the switchable current drive circuit for providing a current through a coil to charge the coil when the switchable current drive circuit is enabled by the first control signal being in a first logic state and for collapsing the current through the coil thereby producing a rising voltage across the coil to fire a spark plug, typically coupled across the coil, when the switchable current drive circuit is disab...
A circuit for driving an inductive load coupled thereto, comprising: charging means for providing current through the inductive load when enabled and for inhibiting current through the inductive load when disabled; a control circuit being responsive to a first input logic signal for providing a first output logic signal for enabling and disabling said charging means when said first output logic signal respectively is in a first and second logic state, said control circuit being responsive to a second input logic signal for both providing a second output ...
