DESCRIPTION

The L482 is an integrated circuit designed for use

with an NPN darlington in breakerless ignition sys-

tems with hall-effect pickup sensors and high energy

ignition coils.

It controls the energy stored in the ignition coil and

the desaturation time of the external darlington to

limit the power dissipation.
