Electronic Ignition Interface
General DescriptionThe LM9011isan interface circuit which integrates the tim-
ing detection and logic control functions required foran
automotive electronic ignition system into one device. VRS interfaceis providedfor crankshaft position informa-
tionviaa toothed-wheel.
Four voltage comparators are providedfor hardware diag-
nostics. electronic timing interface with output fault diagnosticsis
providedto enablea micro-processorto drivean external
four channel ignition spark circuit.
The LM9011is fully specified over the automotive tempera-
ture rangeof -40˚Cto +125˚C, andis availableina28 pin
Small Outline surface mount package.
