FM484 Magnetic Pickup Ignition Controller

The FM484 is an integrated circuit designed for use with an NPN darlington in breakerless ignition systems with magnetic pickup Sensors and high energy ignition coils. For the special design which has two input pins from the pickup, it CAN be used with a wide variety of magnetic Sensors The device drives an NPN external darlington to control the coil current providing the required stored energy with low dissipation. This circuit has many advantages: low power dissipation, stable, high ignition energy, self-protection, widely application conditions, long using life, etc. Its compatible for overseas products of the same class.
