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.

NOTES: 1. Current sourced into Supply pin.
2. Ramp up VCC from 24 to 31 V in 0.1 V increments and note the supply voltage, VCC, which causes VO to fall below 1.0 V.
3. Ramp up VCC from 14 to 20 V in 0.1 V increments and measure VCC when ICA 2.0 µA.
4. Ramp up VCC from 20 to 14 V and measure VCC when ICA 2.0 µA and compute hysteresis difference from VCC1.
5. Voltage measured at Master Bias pin.
