The RTS5413D IC from Realtek is a USB Type-C controller chip that handles Power Delivery (PD) and USB hub control. It is designed to make USB Type-C ports smarter and more efficient.
This IC manages high-speed data transfer, power negotiation, and multiple device connections through one port. It also includes built-in multiplexers (MUX) that switch and control SuperSpeed USB signals, allowing smooth operation between data, charging, and display functions.
The RTS5413D helps simplify circuit design in laptops, docking stations, and adapters by combining several USB-C functions into one reliable chip.
