LM9011 Datasheet | National Semiconductor

Description The LM9011 is an interface circuit which integrates the timing detection and logic control functions required for an automotive electronic ignition system into one device. A VRS interface is provided for crankshaft position information via a toothed-wheel. Four voltage parators are provided for hardware diagnostics. An electronic timing interface with output fault diagnostics is provided to enable a micro-processor to drive an external four channel ignition spark circuit. The LM9011 is fully specified over the automotive temperature range of -40˚C to +125˚C, and is available in a 28 pin Small Outline surface mount package.
