Ignition Control FlipĆChip
MCCF33093
Designed for automotive ignition applications. 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
• Overvoltage Shutdown Protection
• Auto Start-Up Capability Once Overvoltage Condition Ceases
• Allows for Push Start-Up in Automotive Applications
• Ignition Coil Current Limiting
• Ignition Coil Voltage Limiting
• Bandgap Reference for Enhanced Stability Over Temperature
• Negative Edge Filter for Hall Sensor Input Transient Protection
• Hall Sensor Inputs for RPM and Position Sensing
• – 30°C ≤ TA ≤ +140°C Ambient Operating Temperature
