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.
