Integrated Circuit Chip RTS5420 USB3.2 Gen2x1 4-Port Hub Controller QFN-88

Description Of RTS5420

RTS5420 is an advanced USB3.2 Gen2x1 Hub controller that functions as a 4‑Port USB3.2 Gen2x1 Hub, and a 4-Port USB2.0 Hub. It supports USB3.2 Gen2x1 and USB2.0 specifications, and fully backward supports the USB3.2 Gen1 (USB3.0),USB1.1, and USB1.0 specifications. Based on MCU architecture, the RTS5420 can easily update FW for future specification updates, or provide easy feature customization, using an ISP tool.

With an RT smart charger function, the RTS5420 supports most popular charging solutions and supports BC1.2. Additionally, Apple and Samsung charger ports are emulated on each port via the RTS5420’s Auto-Detection-Switch mechanism.

The ‘ACA-Docking’ function defined by the BC1.2 specification is also supported by the RTS5420’s upstream port. When a device that supports the ACA-Dock feature of the BC1.2 specification is connected to an ACA-Dock, it acts as a host to various USB peripherals, such as a hub, keyboard, mouse, printer, etc., while simultaneously this device will be receiving a charge.

The second charger function of the RTS5420’s upstream port is called the ‘charger detection’ function. The RTS5420 supports an auto-detection and switch mechanism; it can recognize the type of BC1.2 device connected to the upstream port, including CDP, DCP, and SDP, and charge the connected device in the correct mode.

The BOM cost is reduced through a combination of factors. The RTS5420 deploys 10Gbps on every port, an LDO regulator is integrated and supplies stable 3.3V for the RTS5420, and lastly a configurable Billboard device is integrated when Alt-Mode is applied.
