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.

The L482 is also particularly suitable for use as ig-

nition control and driving stage in more sophisti-

cated car electronic systems which employ

microprocessor circuits.
