4A Injector Solenoid Driver Description The CS452/453 is a monolithic integrated circuit designed for medium current solenoid driver applications.
Its typical function is to supply full battery voltage to fuel injector(s) for rapid current rise, in order to produce positive injector opening.
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.
