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 comparators 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.
