The MCCF33093 provides outstanding control of the ignition coil when used with an appropriate Motorola Power Darlington Transistor. Engine control systems utilizing the MCCF33093 exhibit exceptional fuel efficiency and low exhaust emissions. The MCCF33093 requires a differential Hall Sensor input for proper operation. The MCCF33093 utilizes Flip-Chip Technology in which solder bumps, rather than traditional wire bonds, are created to establish mechanical and electrical contact to the chip. This process affords a unique device having improved reliability at elevated operating temperatures. • Solder Bumped for Flip-Chip Assembly • • • • • • • • • • External Capacitors to Set Device Timing IGNITION CONTROL FLIP–CHIP SEMICONDUCTOR TECHNICAL DATA FLIP-CHIP CONFIGURATION Overvoltage Shutdown Protection 14 Auto Start-Up Capability Once Overvoltage Condition Ceases Allows for Push Start-Up in Automotive Applications 13 2 12 3 11 4 Ignition Coil Current Limiting Ignition Coil Voltage Limiting Bandgap Reference for Enhanced Stability Over Temperature Negative Edge Filter for Hall Sensor Input Transient Protection 1 Hall Sensor Inputs for RPM and Position Sensing – 30°C ≤ TA ≤ +140°C Ambient Operating Temperature 10 5 9 6 8 7 (Backside View) 0.116 inch x 0.091 inch Backside orientation marking indicated by arrow oriented as shown Simplified Block Diagram and Application Circuit D VCC BUMP CONNECTIONS 55 330 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 12V 0.1µF 15.3k 2 9 8 4.0k 10k 5 10k 6 27k 7 In (+) In (–) SW 1.0k Reference Generator To Ignition Coil 10 Output 11 Logic and Control 200 0.1µF Ramp Adaptive Stall Capacitor Capacitor Capacitor Control Control Control 1 4 3 Select 13 56 14 Ground Master Bias Adaptive Capacitor Ramp Capacitor Positive Hall Input Negative Hall Input Start Supply Distributor Signal Coil Output Process Test Emitter of Darlington Stall Capacitor 0.05 ORDERING INFORMATION 12 Operating Temperature Range Package MCCF33093 TA = –30° to +140°C Flip–Chip Device This document contains information on a product under development.
