USB5533B
3-Port SS/HS USB Hub Controller
General Description
The USB5533B hub is a 3-port SuperSpeed/Hi-Speed,
low-power, configurable hub controller family fully com-
pliant with the USB 3.0 Specification. The USB5533B
supports 5 Gbps SuperSpeed (SS), 480 Mbps Hi-
Speed (HS), 12 Mbps Full-Speed (FS) and 1.5 Mbps
Low-Speed (LS) USB signaling for complete coverage
of all defined USB operating speeds.
The USB5533B supports USB 2.0 speeds through its
USB 2.0 hub controller. The new SuperSpeed hub con-
troller operates in parallel with the USB 2.0 controller,
so the 5 Gbps SuperSpeed data transfers are not
affected by the slower USB 2.0 traffic.
The USB5533B supports battery charging on a per port
basis. On battery charging enabled ports, the devices
provide automatic USB data line handshaking. The
handshaking supports USB 1.2 Charging Downstream
Port (CDP), Dedicated Charging Port (DCP) and non-
USB 1.2 devices.
The USB5533B is configured for operation through
internal default settings, where custom configurations
are supported through an on-chip OTP ROM, an exter-
nal SPI ROM, or SMBus.

USB5533B
1.3 Configurable Features
The USB5533B hub controller provides a default configuration that is sufficient for most applications. When initialized
in the default configuration, the following features may be configured:
• Downstream non-removable ports, where the hub will automatically report as a compound device
• Downstream disabled ports
• Downstream port power control and over-current detection on a ganged or individual basis
• USB signal drive strength
• USB differential pair pin location
The USB5533B hub controllers can alternatively be configured by OTP or as an SMBus slave device. When configured
by an OTP or over SMBus, the following configurable features are provided:
• Support for compound devices on a port-by-port basis
• Selectable over-current sensing and port power control on an individual or ganged basis to match the circuit board
component selection
• Customizable vendor ID, product ID, and device ID
• Configurable delay time for filtering the over-current sense inputs
• Indication of the maximum current that the hub consumes from the USB upstream port
• Indication of the maximum current required for the hub controller
• Custom string descriptors (up to 30 characters): Product, manufacturer, and serial number
