USB5537B 7-Port SS/HS USB Hub Controller Emulates portable/handheld native wall chargers General Description - Charging profiles emulate a handheld The USB5537B hub is a 7-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 USB5537B 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 USB5537B 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 (available on 4 of the 7 ports) operates in parallel with the USB 2.0 controller, so the 5 Gbps SuperSpeed Configuration via OTP ROM, SPI ROM, or SMBus data transfers are not affected by the slower USB 2.0 On-chip 8051 C manages VBUS, and other hub traffic. signals The USB5537B supports battery charging on a per port 8 KB RAM, 32 KB ROM basis.
