Power Supply of FT4232H Hub Module
The GL850G and the FT4232H ICs and their related circuits on the USB Hi-Speed Serial/Hub Module are
The maximum total current consumed by the external usb devices on downstream port 2 and 3 is 1A. If
There are two options to supply power to external downstream usb devices connected to ports 2 and 3.
Note: It is recommened to select the mode of operation before connecting the USB Hi-Speed
Serial/Hub Module.
directly powered by USB bus power. The estimated current consumed by the cirucuits of module is
about 100-300mA depending on the application. It is important that the user ensures that the host can
supply this current via USB.
the total current exceed 1A, the fuse on the USB Hi-Speed Serial/Hub Module will be disconnected. If
this occurs then LEDs D2 and D5 on the module will illuminate to indicate over-current status.
1. Use USB bus power to supply downstream ports:
Connect 5V to VCC_BUS (CN3, pin 3 to CN3, pin 2). This connection uses the power from
2. Use external power to supply downstream ports:
Connect 5V (CN3, pin 3) to external +5v DC power supply. This connection takes the power
upstream USB bus to supply the downstream USB ports of the USB hub. With this connection, user
should make sure that the usb host can supply enough current to the external USB devices – in
addition to the current required by the module.
from external power to supply the downstream USB ports of USB hub. Users should also make sure
that the external power can supply enough current required by the external devices.
