Outputs
6.1.3. 5 A High-Side Output with Current Sense
Capabilities
These outputs provide 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 following table provides specifications for the CM2115's 5 A high-side
outputs:
