Designed for automotive ignition applications in 12 V systems, the MC33094DW provides control of the ignition coil when used with an appropriate NXP® Power Darlington Transistor. Engine control systems utilizing these devices for ignition coil control 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.
