GENERAL DESCRIPTION
That could dramatically reduce the system BOM cost. Besides complies with USB Battery Charging specification rev1.2, RTS5411E also provides charging function for various portable devices. Not only downstream ports can be used as charger, RTS5411E’s upstream port also supports two special functions regarding the BC1.2 specification. The first one charger function of RTS5411E’s upstream port is called “ACA-dock” mode. When a device which complies with ACA-dock of the BC1.2 specification is put into an ACA-Dock, it would act as a host to various USB peripherals, such as a hub, keyboard, mouse, printer, etc. However, while in ACA-dock, the device should also be able to charge at the same time. The second charger function of the RTS5411E’s upstream port is called “charger detection” function. RTS5411E can recognize the BC1.2 charger mode which attached to the upstream port, including CDP, DCP and SDP. RTS5411E supports an auto detection-switch mechanism to charge portable device in suitable mode.
