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
