CS290/291

Ignition Controller

Features

Description

The CS290/291 are integrated cir-

cuits to be used in the automotive

ignition system. The application

diagram shown below highlights

the CS290. The CS291 is identical

with the differential input replaced

by a single-ended input. The part is

capable of withstanding 90V load

dump transients in the circuit

shown below. The part is also

reverse battery protected.
