L497 Hall Effect Pickup Ignition Control IC

The LD497 (analog L497) is an integrated electronic ignition controller for breaker less ignition systems using Hall effect sensors. The device drives an NPN external Darlington to control the coil current providing the required stored energy with low dissipation. A special feature of the LD497 is the programmable time for the recovery of the correct dwell ratio Td/T when the coil peak current fails to reach 94% of the nominal value. In this way only one spark may have an energy less than 94% of the nominal one during fast acceleration or cold starts.

MC3334 High Energy Ignition Circuit IC

LD3334 (analog MC3334) is designed to use the signal from a reluctor type ignition pickup to produce a well controlled output from a power Darlington output transistor.

MC79076 Electronic Ignition Control Circuit

The LD3335 (analog MC79076), in conjunction with an appropriate Power Darlington Transistor, provides an economical solution for automotive ignition applications. The LD3335offers optimum performance by providing closed loop operation of the Power Darlington in controlling the ignition coil current.
