DESCRIPTION
The L497 is an integrated electronic ignition control-
ler for breakerless ignition systems using Hall effect
sensors.
ORDERING NUMBERS : L497B (DIP16)
L497D1 (SO16)
DIP16
SO16
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.
