Electronic Switching Circuit

The CA3165 is a single chip electronic switching circuit intended primarily for ignition applications. It includes an Oscillator that is amplitude-modulated by the rotor teeth of a distributor, a detector that develops the positive going modu- lation envelope, a Schmitt Trigger that eliminates switching uncertainties. Both types include two complementary high current switched outputs for driving Power Transistors requir- ing up to 120mA. The CA3165E also includes two comple- mentary low current outputs that incorporate internal current limiting and a non-inverting output amplier with uncommit- ted input capable of switching 27mA. The CA3165 is supplied in the 8 lead dual-in-line plastic package (E sufx) and in the 14 lead dual-in-line plastic package (E1 sufx). By Intersil Corporation
