TUSB2046x 4-Port Hub for the Universal Serial Bus With Optional
Serial EEPROM Interface Features
Fully Compliant With the USB Specificationasa
Full-Speed Hub: TID #30220231 32-Pin LQFP(1) Package Witha 0.8-mm Terminal
Pitchor QFN Package Witha 0.5-mm Pin Pitch 3.3-V Low-Power ASIC Logic Integrated USB Transceivers State Machine Implementation Requires No
Firmware Programming One Upstream Port and Four Downstream Ports All Downstream Ports Support Full-Speed and
Low-Speed Operations Two Power Source Modes Self-Powered Mode Bus-Powered Mode Power Switching and Overcurrent ReportingIs
Provided Gangedor Per Port Supports Suspend and Resume Operations Supports Programmable VendorID and Product With External Serial EEPROM 3-State EEPROM Interface Allows EEPROM
Sharing Push-Pull Outputs for PWRON Eliminate the Need
for External Pullup Resistors Noise Filteringon OVRCUR Provides Immunityto
Voltage Spikes Package Pinout Allows 2-Layer PCB Low EMI Emission Achievedbya 6-MHz Crystal
Input Migrated From Proven TUSB2040 Hub Lower Cost Than the TUSB2040 Hub Enhanced System ESD Performance Requirements; Works Operating System With USBa Applications Computer Systems Docking Stations Description
The TUSB2046xisa 3.3-V CMOS hub device that
provides one upstream port and four downstream
portsin compliance with the Universal Serial Bus
(USB) specificationasa full-speed hub. Because this
deviceis implemented witha digital state machine
insteadofa microcontroller,no firmware
programming is required. Fully compliant USB
transceivers are integrated into the ASIC for all
upstream and downstream ports. The downstream
ports support full-speed and low-speed devices by
automatically setting the slew rate accordingto the
speed of the device attached to the ports. The
configurationof the BUSPWR pin selects either the
bus-poweredor the self-powered mode.
Configuring the GANGED input determines the power
switching and overcurrent detection modes for the
downstream ports.If GANGEDis high, all PWRON
outputs switch together andif any OVRCUR is
activated,all ports transitionto the power-off state.If
GANGEDis low, the PWRON outputs and OVRCUR
inputs operateona per-port basis.
