LM9011

Contents

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.
