USB5532B 2-Port SS/HS USB Hub Controller Emulates portable/handheld native wall chargers General Description - Charging profiles emulate a handheld The USB5532B hub is a 2-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 USB5532B 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 USB5532B 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. On-chip 8051 C manages VBUS, and other hub signals The USB5532B supports battery charging on a per port basis. On battery charging enabled ports, the devices 8 KB RAM, 32 KB ROM provide automatic USB data line handshaking. The One Time programmable (OTP) ROM: 8 kbit handshaking supports USB 1.2 Charging Downstream - Includes on-chip charge pump Port (CDP), Dedicated Charging Port (DCP) and non- Single 25 MHz XTAL or clock input for all on-chip USB 1.2 devices.
