USB3803
USB 2.0 High-Speed Hub Controller Optimized
for Portable Applications
Features
• Integrated USB 2.0 Compatible 3-Port Hub
• Advanced power saving features
- 1 μA Typical Standby Current
- Port goes into power saving state when no
devices are connected downstream
- Port is shutdown when port is disabled
- Digital core shut down in Bypass (USB3803C
only) and Standby Mode
• Provides USB Battery Charger Detection for:
- USB-IF Battery Charging 1.1 compliant Dedi-
cated Charging Ports (DCP)
- USB-IF Battery Charging 1.1 compliant
Charging Downstream Port (CDP)
- Standard Downstream Port (SDP); ie. USB
host or downstream hub port
- 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 take
communicate with the internal and peripheral devices.
