    Hello Xiaoxiang, 

    This is dependent on the current limit set by the device. If ILIM is not externally configured the device relies on the internal current limit. I have attached a device comparison below. 

    Version F has the highest current range at 94A while version A can go up to 32A. When IOUT reaches the current limit threshold, ICL, the channel will switch off immediately. RILIM = GND is assumed to be a state where RILIM is shorted rather than intended state. 

    BR,
