BUSPWR is an active-low input that indicates whether the downstream ports source their power from the USB cable or a local power supply. For the bus-power mode, this terminal must be pulled low, and for the self-powered mode, this terminal must be pulled to 3.3 V. Input must not change dynamically during operation.

TUSB2077A www.ti.com SLLS414E – MARCH 2000 – REVISED SEPTEMBER 2013 USB Design Notes The following sections provide block diagram examples of how to implement the TUSB2077A device. Note, even though no resistors are shown, pullup, pulldown, and series resistors must be used to properly implement this device. Figure 6 is a block diagram example of how to connect the external EEPROM if a custom product ID and vendor ID are desired. Figure 7 is an example of how to generate the 6-MHz clock signal.

TUSB2077A SLLS414E – MARCH 2000 – REVISED SEPTEMBER 2013 www.ti.com Programming the EEPROM An SGS Thompson M93C46 EEPROM, or equivalent, stores the programmable VID and PID. When the EEPROM interface is enabled (EXTMEM = 0), the EECLK and EEDATA are internally pulled down (100 μA) inside the TUSB2077A. The internal pulldowns are disabled when the EEPROM interface is disabled (EXTMEM = 1). The EEPROM is programmed with the three 16-bit locations as shown in Table 1.

TUSB2077A SLLS414E – MARCH 2000 – REVISED SEPTEMBER 2013 www.ti.com Bus-Powered Hub, Ganged-Port Power Management When used in bus-powered mode, the TUSB2077A supports up to four downstream ports by controlling a TPS2041 device which is capable of supplying 100 mA of current to each downstream port. Bus-powered hubs must implement power switching to ensure current demand is held below 100 mA when the hub is hot-plugged into the system.
PAGE 13
TUSB2077A www.ti.com SLLS414E – MARCH 2000 – REVISED SEPTEMBER 2013 Self-Powered Hub, Individual-Port Power Management In a self-powered configuration, the TUSB2077A can be implemented for individual-port power management when used with two TPS2044 because it is capable of supplying 500 mA of current to each downstream port and can provide current limiting on a per port basis.
PAGE 14
TUSB2077A SLLS414E – MARCH 2000 – REVISED SEPTEMBER 2013 www.ti.com Self-Powered Hub, Ganged-Port Power Management The TUSB2077A can also be implemented for ganged-port power management in a self-powered configuration. The implementation is very similar to the bus-powered example with the exception that a self-powered port supplies 500 mA of current to each downstream port. The overcurrent protection can be provided by a TPS2044 quad device or a TPS2024 single power switch.
