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 compliant with the USB 3.0 Specification. The USB5533B
supports 5 Gbps SuperSpeed (SS), 480 Mbps HiSpeed (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 controller 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 nonUSB 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 external SPI ROM, or SMBus. Product Features USB 3.0 compliant 5 Gbps, 480 Mbps, 12 Mbps
and 1.5 Mbps operation, USB pins are 5 V tolerant
