The L497is anintegratedelectronicignitioncontroller for breakerless ignition systemsusing Hall effect sensors.
The device drives an NPN external darlington to controlthe coil current providingthe requiredstored energy with low dissipation.
A special feature of the L497 is the programmable time for the recovery of the correct dwell ratio Td/T when the coil peakcurrent fails to reach 94%of the nominal value. In this wayonly one sparkmayhave an energyless than 94% of the nominalone during fast accelerationor cold starts
