L482 HALL- EFFECT PICKUP IGNITION CONTROLLER - . . . DIRECT DRIVING OF THE EXTERNAL POWER DARLINGTON COIL CURRENT CHARGING ANGLE (DWELL) CONTROL COIL CURRENT PEAK VALUE LIMITATION CONTINUOUS COIL CURRENT PROTECTION CONDUCTION AND DESATURATION TIME OUTPUT SIGNALS PERMANENT CONDUCTION PROTECTION RESET OUTPUT SIGNAL OVERVOLTAGE PROTECTION FOR EXTERNAL DARLINGTON LOAD DUMP PROTECTION DIP16 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. PIN CONNECTIONS (top views) SO16 ORDERING NUMBERS : L482 (DIP16) L482D1 (SO16) The L482 is also particularly suitable for use as ignition control and driving stage in more sophisticated car electronic systems which employ microprocessor circuits.
