The CS452/453 is a monolithic inte-

grated circuit designed for medium

current solenoid driver applica-

tions. Its typical function is to sup-

ply full battery voltage to fuel injec-

tor(s) for rapid current rise, in order

to produce positive injector open-

ing.

When load current reaches a preset

level (2.4A for CS452, or 4.4A for

CS453), the injector driver reduces

the load current by a 4:1 ratio and

operates as a constant current

source. This condition holds the

injector open and reduces system

power dissipation.

Other solenoid or relay applications

can be equally well served by the

CS452/453. Two high impedance

inputs are provided which permit a

variety of control options and can

be driven by TTL or CMOS logic.
