TUSB2046Bx 4-Port Hub for the Universal Serial Bus With Optional

Serial EEPROM Interface

1 Features

2 Applications

•

Fully Compliant With the USB Specification as a

Full-Speed Hub: TID #30220231

•

Computer Systems

Docking Stations

•

Pitch or QFN Package With a 0.5-mm Pin Pitch

3 Description

The TUSB2046B is a 3.3-V CMOS hub device that

provides one upstream port and four downstream

ports in compliance with the Universal Serial Bus

(USB) specification as a full-speed hub. Because this

device is implemented with a digital state machine

instead of a 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 according to the

speed of the device attached to the ports. The

configuration of the BUSPWR pin selects either the

bus-powered or the self-powered mode.

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 Reporting Is

Provided Ganged or Per Port

Configuring the GANGED input determines the power

switching and overcurrent detection modes for the

downstream ports. If GANGED is high, all PWRON

outputs switch together and if any OVRCUR is

activated, all ports transition to the power-off state. If

GANGED is low, the PWRON outputs and OVRCUR

inputs operate on a per-port basis.

•

Supports Suspend and Resume Operations

Supports Programmable Vendor ID and Product

ID With External Serial EEPROM

•

3-State EEPROM Interface Allows EEPROM

Sharing

Push-Pull Outputs for PWRON Eliminate the Need

for External Pullup Resistors

Device Information⁽¹⁾

Noise Filtering on OVRCUR Provides Immunity to

Voltage Spikes
