DESCRIPTION

The L482 is an integrated circuit designed for use with an NPN darlington in breakerless ignition systems 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 ignition control and driving stage in more sophisticated car electronic systems which employ microprocessor circuits.
