Introduction

U2H4BC07 is a high-performance 4 ports USB 2.0 Hub which compliant with Battery Charging BC 1.2.

  • Upstream Port Connected: Supports SDP & CDP (depends on external device)
  • Upstream Port Unconnected: Auto S & C (Sleep and Charge) Mode

As USB charging has gained popularity, the 500 mA minimum defined by USB 2.0 has become insufficient for many handset and personal media players which need a higher charging rate. Several new standards have been introduced defining protocol handshaking methods that allow host and client devices to acknowledge and draw additional current beyond the 500 mA minimum defined by USB 2.0.

The U2H4BC07 supports three of the most common protocols:

  • USB 2.0 Battery Charging Specification BC1.2 (draft)
  • Chinese Telecommunications Industry Standard YD/T 1591-2009
  • Divider Mode, compliant with Apple devices such as iPod® and iPhone®

All three methods have similarities and differences, but the biggest commonality is that all three define three types of charging ports that provide charging current to client-side devices. These charging ports are defined as:

  • Standard Downstream Port (USB 2.0) (SDP)
  • Charging Downstream Port (CDP)
  • Dedicated Charging Port (DCP)

BC1.2 (draft) defines a Charging Port as a downstream facing USB port that provides power for charging portable equipment.
The table below shows the differences between these ports according to BC1.2 (draft).

PORT TYPE       SUPPORTS USB 2.0 COMMUNICATION            MAXIMUM ALLOWABLE CURRENT DRAW BY PORTABLE EQUIPMENT (A)
SDP (USB 2.0) Yes  0.5
CDP Yes 1.5
DCP No 1.5

 

U2H4BC07 is designed with Multiple Transaction Translator (MTT) USB 2.0 HUB controller.

Multiple Transaction Translator (MTT) provides individual TT control logics for each downstream port. This is a performance better choice for USB 2.0 Hub.

The U2H4BC07 works backward compatible either when any one of downstream ports is connected to an USB 1.1 compliant device, or when the upstream port is connected to a USB 1.1 compliant host.
