Outputs 

 

6.1.4.  2.5 A High-Side Output with Current Sense 

Capabilities 

These outputs provide 2.5 A maximum continuous current with accurate current 
sensing. The current sensing provides accurate readings to detect single load 
disconnect on parallel driven load applications (i.e. when multiple loads are 
driven by a single output). The current sensing can also be used for regulating 
current control of hydraulic coils. 

The following table provides specifications for the CM2115's 2.5 A high-side 
outputs:
