Order this document from Analog Marketing 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 Flip–Chip 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 Flip–Chip Assembly • • • • • • ELECTRONIC IGNITION CONTROL CIRCUIT SEMICONDUCTOR TECHNICAL DATA Ignition Coil Voltage Internally Limited to 375 V DW SUFFIX PLASTIC PACKAGE CASE 751G (SO–16L) Coil Current Limiting to 7.5 A Output On–Time (Dwell) Control Dwell Feedback Control to Sense Coil Variation Hall Sensor Input – 30°C ≤ TA ≤ +140°C Ambient Operating Temperature FLIP–CHIP CONFIGURATION 1 2 13 3 12 4 11 5 10 6 9 7 Simplified Block Diagram and Application Circuit 8 Top View (Bump Side) BUMP CONNECTIONS 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.
