Programmable USB Port Power Controller with Charger Emulation

Datasheet

SMSC UCS1002

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.
