CA3165 Datasheet Electronic Switching Circuit

Manufacturer: Intersil (now Renesas)

Overview: May 1999 CT T ODU CEMEN 7 R P E A 74 T L OLE REP 00-442-7 OBS ENDED 8 M ns 1 .

General Description

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 modulation envelope, a Schmitt trigger that eliminates switching uncertainties.

Both types include two plementary high current switched outputs for driving power transistors requiring up to 120mA.

Key Features

  • Switching Initiated by Damping of Internal Oscillator.
  • Proximity Sensing of Rotational Motion.
