The RTS5423 is an advanced USB3.2 Gen2x1 Hub and PD3.0 controller supporting up to two ports full featured Type-C, and 3 ports Type-A connectors that function as a 4-Port USB3.2 Gen2x1 Hub, a 4-Port USB2.0 Hub, and a 2-Port PD3.0 controller. It supports USB3.2 Gen2x1, USB2.0, Type-C, and PD3.0 specifications, and fully backward supports the USB3.2 Gen1, USB1.1, and USB1.0 specifications. Based on MCU architecture, the RTS5423 can easily update FW for future specification updates, or provide easy feature customization, using an ISP tool.
With an RT smart charger function, the RTS5423 supports most popular charging solutions and supports BC1.2 and PD3.0. It also implements CC terminations defined by Type-C specification Revision1.2 for current advertisements. Additionally, Apple and Samsung charger ports are emulated on every port with the RTS5423’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 can be receiving a charge.
The BOM cost is reduced through a combination of factors. The RTS5423 deploys 10Gbps 1:2 MUX on the upstream port and downstream port 1, which is necessary for Type-C’s plug flip-ability. An LDO regulator is integrated, supplying stable 3.3V for the RTS5423. In DP-Alt mode, a HPD pin is used for DP plug detection. With a high resolution ADC of up to 4 channels, the RTS5423 can monitor the current and voltage of each port simultaneously for OCP, UVP, and OVP protection. There is also a configurable Billboard device integrated, which is important when Alt-Mode is applied.
The RTS5423 has various interfaces such as GPIOs, I2C, and SMBUS, for controlling or communicating with other components, such as a PMU (Power Management Unit) for Type-C VBUS management.
The RTS5423 supports a special power saving function named ‘Delink mode’. When no device is attached, the RTS5420 can switch to a deeper suspend mode similar to ‘Disconnected’.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
RTS5423 is an authentic electronic component manufactured by Realtek, categorized under Interface ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official RTS5423 datasheet above.
Electronic component spot-market pricing for RTS5423 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for RTS5423 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
