Output current (Note 12)
This is the total current requirement for the USB-1408FS which includes up to 10 mA for the
Note 10:
status LED.
Self-powered hub refers to a USB hub with an external power supply. Self-powered hubs allow a
Note 11:
connected USB device to draw up to 500 mA.
Root port hubs reside in the PC's USB host controller. The USB port(s) on your PC are root port
hubs. All externally powered root port hubs (desktop PCs) provide up to 500 mA of current for a
USB device. Battery-powered root port hubs provide 100 mA or 500 mA, depending upon the
manufacturer. A laptop PC that is not connected to an external power adapter is an example of a
battery-powered root port hub.
Bus powered hubs receive power from a self-powered or root port hub. In this case the maximum
current available from the USB +5 V is 100 mA. The minimum USB +5 V voltage level can be
as low as 4.1 V.
Note 12: Output current refers to the total amount of current that can be sourced from the USB +5 V,
analog outputs and digital outputs.
