TPS2H160-Q1: Current limit - per channel or total?

Part Number: TPS2H160-Q1


Tool/software:

Hi there,

I have gone through the datasheet but am unable to find clear direction on my question. Is the current limit that you set applicable to the sum of both channels? Or if either channel hits the current limit will a fault be set? 

For example, I have two channels that each should be limited to 500mA, I am not sure whether I should set the limit to 500mA, or to 1A to account for the sum of both currents.

Thanks in advance!

Steven
