TPS274160: External current limit per channel or for whole device?

Hello everybody,

I have a question about the external current limit which is set per R_CL.

I can't find any hint in the datasheet if the value of I_OUT is the current limit for each channel or the whole device. Here a quick example: If i set the current limit to 0.5 A with a 4k resistor can i operate all 4 channels with 0.5 A or ist the sum of the current of all 4 channels limited to 0.5 A.

Thanks a lot for any help
