the mccf79076, in conjunction with an appropriate motorola power darlington transistor, provides an economical solution for automotive ignition applications. the mccf79076 offers optimum performance by providing closed loop operation of the power darlington in controlling the ignition coil current. the mccf79076 incorporates flipchip technology which involves the formation of solder bumps, rather than traditional wire bonds, to establish mechanical and electrical contact to the semiconductor chip. this process affords a unique device having improved reliability at elevated operating temperatures. ? solder bumped for flipchip assembly ? ignition coil voltage internally limited to 375 v ? coil current limiting to 7.5 a ? output ontime (dwell) control ? dwell feedback control to sense coil variation ? hall sensor input ? 30 c t a +140 c ambient operating temperature simplified block diagram and application circuit est. input ref. output bypass input hall sensor input 13 12 11 10 9 8 7 6 5 4 3 2 1 logic and control output reference generator v cc to ignition coil this document contains information on a product under development. motorola reserves the right to change or discontinue this product without notice. ? motorola, inc. 1996 issue 0
