35 / 114 page  Programmable USB Port Power Controller with Charger Emulation Datasheet SMSC UCS1002 35 Revision 1.4 (07-16-13) DATASHEET Figure 5.2 shows a system configuration in which the UCS1002 provides a USB data switch, port power switch, low power Attach Detection, and portable device Attach / Removal Detection signaling. This configuration does not include configurable data line charger emulation, programmable current limiting, or current monitoring and rationing. Figure 5.3 shows a system configuration in which the UCS1002 provides a port power switch, low power Attach Detection, and portable device attachment detected signaling. This configuration is useful for applications that already provide USB BC1.2 and/or legacy data line handshaking on the USB data lines, but still require port power switching and current limiting.
