CS452/453  
2.4A/4.4A Injector Solenoid Driver  
Description  
Features  
The CS452/453 is a monolithic inte-  
the load current by a 4:1 ratio and  
operates as a constant current  
source. This condition holds the  
injector open and reduces system

tor(s) for rapid current rise, in order  
to produce positive injector open-  
ing.  
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.  
Low Thermal Resistance
