USB 2.0 High-Speed Hub Controller Optimized

for Portable Applications

• VariSense^TM

Features

- Programmable USB receiver sensitivity

• flexPWR^®Technology

• Integrated USB 2.0 Compatible 3-Port Hub

• Advanced power saving features:

- 1 A Typical Standby Current

- Port goes into power saving state when no

devices are connected downstream

- Low current design ideal for battery powered

applications

- Internal supply switching provides low power

modes

- Port is shut down when port is disabled

• External 12, 19.2, 26, or 38.4 MHz clock input

- Digital core shutdown in Bypass and Standby

Modes

• Internal 3.3V & 1.2V Voltage Regulators for single

supply operation

• Provides USB Battery Charger Detection for:

- External VBAT and 1.8V dual supply input

option

cated Charging Ports (DCP)

• Internal Short Circuit protection of USB differential

signal pins

- USB-IF Battery Charging 1.1 compliant

Charging Downstream Port (CDP)

• ±5kV HBM ESD Protection

- Standard Downstream Port (SDP); that is,

USB host or downstream hub port

• 25-pin WLCS (1.95mm x 1.95mm Wafer Level

Chip Scale) Package - 0.4mm ball pitch

- Downstream Hub Ports Support USB-IF Bat-

tery Charging 1.1 as Charging Downstream

Port (CDP)

Target Applications

The USB3803 is targeted for applications where more

than one USB port is required. As mobile devices add

more features and the systems become more complex,

it is necessary to have more than one USB port to com-

municate with internal and peripheral devices.

• Supports either Single-TT or Multi-TT configura-

tions for Full-Speed and Low-Speed connections

(when connected to a High-Speed host)

• Bypass Switch for low power single port operation

- Battery charging detection using a PMIC

- Stereo and mono/mic audio

• Mobile Phones

• Ultra Mobile PCs

- USB1.1 Data

• Tablet Computers

• Enhanced configuration options available through

serial I²C Slave Port

• Digital Still Cameras

• Digital Video Camcorders

• Gaming Consoles

- VID/PID/DID

- String Descriptors

• PDAs

- Configuration options for Hub

• Portable Media Players

• GPS Personal Navigation Devices

• Media Players/Viewers

• Internal Default configuration option when serial

I²C host is not available

• MultiTRAK^TM
