MC3334 datasheet, circuit
High Energy Ignition Circuit
This device is designed to use the signal from a reluctor type ignition
pickup to produce a well controlled output from a power Darlington output
transistor.
Very Low Peripheral Component Count
No Critical System Resistors
Wide Supply Voltage Operating Range (4.0 V to 24 V)
Overvoltage Shutdown (30 V)
Dwell Automatically Adjusts to Produce Optimum Stored Energy
without Waste
Externally Adjustable Peak Current
Available in Chip and Flip–Chip Form
Transient Protected Inputs and Outputs
