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 MC33094 is designed to be controlled from a singleended Hall Sensor input. The circuit is built using highdensity IntegratedInjection Logic (IIL) processing incorporating high currentgain PNP and NPN transistors.

The MC33094DW is packaged in an economical surface mount package and specified over an ambient temperature of 40  to 125  with a maximum junction temperature of 150 .
