UL497 HALL EFFECT PICKUP IGNITION CONTROLLER
As an integrated electronic ignition controller for breakerless ignition systems which uses Hall effect sensors, the UTC UL497drives an NPN external darlington to control the coil current providing the required stored energy with low dissipation. One of the UTC UL497 special features is the programmable time for the recovery of the correct dwell ratio Td/T while the coil peak current fails to reach 94 % of the nominal value.
■FEATURES：
● Direct driving of the external power darlington
● Coil current charent charging angle control
● Programme coil current peak limitation
● When 94% nominal current not reached programmable dwell recovery time
● RPM output
● Has peranent conduction protection
● Overvoltage protection
● Internal supply zener
● Reverse battery protection
