Advance Information
Ignition Control
Designed for automotive ignition applications in 12 V systems, the
MC33094DW provides outstanding control of the ignition coil when used
with an appropriate Motorola Power Darlington Transistor. Engine control
systems utilizing these devices for ignition coil control exhibit exceptional
fuel efficiency and low exhaust emissions. The device is designed to be
controlled from a single–ended Hall Sensor input. The circuit is built using
high–density Integrated–Injection Logic (IIL) processing incorporating high
current–gain PNP and NPN transistors.
The MC33094DW is packaged in an economical surface mount package
and specified over an ambient temperature of –40°C to 125°C with a
maximum junction temperature of 150°C.
• External Capacitors Program the Devices Timing Characteristics

NOTES: 1. Capability measured by forcing the Output to 2.0 V with Current Sense pin (IS) open while measuring the Output current to ground.
2. Measured by clamping the output to that output voltage with IS pin to ground; then increasing VD from 6.0 to 18 V and measuring output leakage
current to ground.
3. Output Clamp voltage with reference to ground while forcing 10 mA into the Dynamic Clamp pin (CL).
4. Output Clamp impedance measured with ICL = 11 ± 1.0 mA into the Dynamic Clamp pin (CL) and noting the corresponding Output Clamp Voltage
change (ZCL = ∆VCL/∆ICL).
5. Dwell is defined as Run Mode Down Current divided by the Run Mode Up Current times the Ramp Control Current Ratio and is calculated from other
measured characteristics as defined above.
6. Set the VCR voltage to 1.5 V; Ramp VCR voltage from 1.8 to 2.2 V in 0.02 V increments and note the Ramp voltage (VCR) which causes the Output
voltage to go > 1.0 V; VCRO = 2.0 V – VCR.

NOTES: 1. Measure time until VO > 0.2 V. The Negative Edge Filter prevents multiple output sparks caused by switching transients present at the input by
disabling the once used input for the filter time t.
2. Propagation delay time measurement of input to output response; Step change Vin(–) from 0 to 10 V. Measure the time required for
VO < 1.5 V.
