SLVS287B – SEPTEMBER 2000 – REVISED SEPTEMBER 2007
(1) This hybrid hub can also be implemented by connecting a 5-V power supply to the SP input of the TPS2071 and
eliminating the external FET. However, this type of implementation is best suited for the TPS2074/75 (see the
TPS2074, TPS2075 Four-Port USB Hub Power Controllers data sheet, SLVS288 , for details).
