DESCRIPTION
The L484 is an integrated circuit designed for use
with an NPN darlington in breakerless ignition sys-
tems with magnetic pickup sensors and high energy
ignition coils.
A key feature of the L484 is flexibility. It can be used
with a wide variety of magnetic sensors thanks to the
LINGTON
NETIC PICKUP TYPES
PROTECTION
TECTION
(ANTI KNOCK SYSTEM)
DIRECT DRIVING OF THE EXTERNAL DAR-
OPERATES WITH A WIDE RANGE OF MAG-
CHARGING ANGLE (DWELL) CONTROL
COIL CURRENT PEAK LIMITATION
CONTINUOUS COIL CURRENT PROTECTION
TACHOMETER SIGNAL OUTPUT
EXTERNAL DARLINGTON OVERVOLTAGE
LOAD DUMP AND REVERSE BATTERY PRO-
POSSIBILITY OF SPARK POINT DELAYING
®
MAGNETIC PICKUP IGNITION CONTROLLER
special design which has two input pins from the
pickup ; the first is the zero crossing detector for the
ignition command and the second pin is used to cal-
culate the dwell time. Moreover another pin is used
to adapt the L484 to various pickup types.
Other features of the device include darlington over-
voltage protection, dump protection, a supply volt-
age range of 6-28 V.
