USB5534B Datasheet, PDF (23/73 Pages) Microchip Technology – 4-Port SS/HS USB Hub Controller

USB5534B
In this configuration, the UCS1002 is utilized as an SMBus enabled port power switch and all charging port handshaking
on the D+/D- signals are controlled directly from the USB5534B. An example implementation can be seen in Figure 4-
14.
