CS453 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...
