MC33191
12V IGNITION DRIVER
SILICON MONOLITHIC
INTEGRATED CIRCUIT
The MC33191 is for use in 12V ignition systems designed for use in
harsh automotive and industrial applications which require the capability of
handling high voltage attributed to load and Þeld dump transients. In
addition, the device can be used under reverse and double battery
conditions.
The MC33191 is available in a 16 pin narrow body DIP plastic and SO
package.
