USB5534B 4-Port SS/HS USB Hub Controller Emulates portable/handheld native wall chargers General Description - Charging profiles emulate a handheld The USB5534B hub is a 4-port SuperSpeed/Hi-Speed, devices wall charger to enable fast charging low-power, configurable hub controller family fully com- (minutes vs. hours) pliant with the USB 3.0 Specification. The USB5534B Enables charging from a mobile platform that is supports 5Gbps SuperSpeed (SS), 480Mbps Hi- off Speed (HS), 12 Mbps Full-Speed (FS) and 1.5 Mbps Support tablets high current requirements Low-Speed (LS) USB signaling for complete coverage of all defined USB operating speeds. Optimized for low-power operation and low ther- mal dissipation The USB5534B supports USB 2.0 speeds through its Vendor Specific Messaging (VSM) support for USB 2.0 hub controller. The new SuperSpeed hub con- firmware upload over USB troller operates in parallel with the USB 2.0 controller, so the 5Gbps SuperSpeed data transfers are not Configuration via OTP ROM, SPI ROM, or SMBus affected by the slower USB 2.0 traffic. Intelligent charge management with UCS1002 control The USB5534B supports battery charging on a per port basis. On battery charging enabled ports, the devices On-chip 8051 C manages VBUS, and other hub provide automatic USB data line handshaking.
