BQ24079: What is the current limit for USB suspend mode of DPM?

Part Number: BQ24079

The table 1 of the BQ24079 datasheet indicates the DPM is in Standby (USB suspend mode) when EN2 and EN1 are "11". But what is the current limit of Standby mode for Vin?

the reason I am asking is, I would like to know if the BQ24079 is connected to an external DC source but EN2 and EN1 setting is wrong, what does BQ24079 will behave?

Thanks,

    HelloJeff,
    When in USB Suspend Mode, the input FET is turned off so there will be only about 50uA current going into the device when VIN = 6. In USB suspend mode, the battery won't be charged and there will be 0V on the output.
