DESCRIPTION

The L484 is an integrated circuit designed for use with an NPN darlington in breakerless ignition systems 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 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 calculate 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.
