General Description RTS5411 is an advanced USB3.0 4-port HUB controller, which integrates USB3.0 and USB2.0 Transceivers, MCU, SIE, regulator and charger circuits into a single chip. That could dramatically reduce the system BOM cost. With high compatibility, RTS5411 is fully backward compatible to USB2.0 and USB1.1 specification which can be operated in Super-Speed, High-Speed, Full-Speed and Low-Speed. RTS5411 provides the battery charging function for each downstream port. Besides complies with USB Battery Charging specification rev1.2, RTS5411 also provides charging function for various portable devices. Not only downstream ports can be used as charger, RTS5411’s upstream port also supports two special functions regarding the BC1.2 specification. The first one charger function of RTS5411’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 RTS5411’s upstream port is called “charger detection” function. RTS5411 can recognize the BC1.2 charger mode which attached to the upstream port, including CDP, DCP and SDP. RTS5411 supports an auto detection-switch mechanism to charge portable device in suitable mode. RTS5411 can update its firmware with an external SPI flash through flexible ISP channel. With the ISP function, it can configure lots of features and settings by the external SPI flash or EEPROM as well. The ISP function is easy to complete with just one USB cable and RTS5411’s download tool. The features and settings of RTS5411 can also be configured by the SMBUS interface or internal eFuse. RTS5411 has various interfaces to communicate with other components, such as GPIO, I2C, SMBUS. It’s flexible for extending varieties of applications by using these interfaces. Moreover, RTS5411 supports a special power saving function named delink mode. It can save more power for the system when there is no device connected to the hub even though the upstream port of the RTS5411 is attached to the downstream port of the behind host or hub.

The connection of the upstream port will be established automatically once there is any device attached to its downstream ports. Realtek Semiconductor Corp. 3 V1.2 RTS5411 3.

So this is the worst case for SS power consumption Realtek Semiconductor Corp. 13 V1.2 RTS5411 The following consumption value applies upon the typical condition with on-chip Switch Regulator operating. Only VDD33 needs to be provided in this 3.3V mode. TA= 25°C, VDD33(VDV33) = 3.3 V.

So this is the worst case for SS power consumption Realtek Semiconductor Corp. 14 V1.2 RTS5411 5.6 Power On/Off Sequence When the on-chip LDO and switch regulator are not used, both 1.2V and 3.3V power need to be provided externally. The power on/off sequence between 1.2V and 3.3V need to be noticed as in Figure 5-1. During power on, it is recommended that the point where both power supplies are stabilized should be no later than 50ms after the start of the 3.3V rising. During power off, the end of 1.2V falling should be no later than 350ms after the start of 3.3V falling. Meanwhile, the falling time (0.9VDD to 0.1VDD) of 3.3V power should be no less than 50us. During the whole process, the voltage of 3.3V power should be always above the 1.2V power. When the 5V to 3.3V LDO is used and 1.2V power is provided externally. The power on/off sequence between 1.2V and 5V should be as the same as the sequence between 1.2V and 3.3V mentioned above. 3.3V 0.9VDD 1.2V 0.1VDD 0.9VDD 0.1VDD GND
