DESCRIPTION
The L484 is an integrated circuit designed for use
with an NPN darlington in breakerless ignition sy-
stemswithmagneticpickupsensorsandhigh ener-
gy ignition coils.
A keyfeatureofthe L484isflexibility. It canbeused
withawidevarietyofmagneticsensorsthankstothe
specialdesignwhichhastwoinputpinsfromthepic-
kup ; the first is the zero crossing detector for the
ignitioncommandandthesecondpinis usedtocal-
culatethe dwelltime. Moreover anotherpin is used
to adaptthe L484 to various pickup types.
Otherfeaturesofthedeviceincludedarlingtonover-
voltage protection, dump protection, a supply volt-
age range of 6-28 V.
