DESCRIPTION
The L497is an integrated electronic ignition controller for breakerless ignition systems using Hall effect sensors.
The device drives an NPN external darlington to control the coil current providing the required stored 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 peak current fails to reach 94 of the nominal value. In this way only one spark may have an energy less than 94 of the nominal one during fast acceleration or cold starts.
■ DIRECT DRIVING OF THE EXTERNAL POWER DARLINGTON
■ COIL CURRENT CHARGING ANGLE (dwell) CONTROL
■ PROGRAMMECOIL CURRENT PEAKLIMITATION
■ PROGRAMMABLE DWELL RECOVERY TIME WHEN 94 NOMINAL CURRENT NOT REACHED
■ RPM OUTPUT
■ PERMANENT CONDUCTION PROTECTION
■ OVERVOLTAGE PROTECTION FOR EXTERNAL DARLINGTON
■ INTERNAL SUPPLY ZENER
■ REVERSE BATTERY PROTECTION
