The USB5744T/2G is a high-performance, low-power USB hub controller manufactured by Microchip Technology. Belonging to the USB5744 series, this integrated circuit features four downstream USB 3.2 Gen 1 ports, supporting SuperSpeed data transfer rates of up to 5Gbps while maintaining compatibility with USB 2.0 devices.
Designed for embedded USB connectivity and high-speed peripheral expansion, the USB5744T/2G supports USB SuperSpeed (5Gbps), Hi-Speed (480Mbps), Full-Speed (12Mbps), and Low-Speed (1.5Mbps) operation. Its integrated USB 3.2 Gen 1 and USB 2.0 hub controllers enable connectivity with a wide range of USB peripheral devices.
The device incorporates USB Battery Charging Specification Revision 1.2 support, including Dedicated Charging Port (DCP), Charging Downstream Port (CDP), and Standard Downstream Port (SDP) configurations. External power switching and supply circuitry are required to deliver charging current to connected devices.
The USB5744T/2G provides flexible OEM configuration through on-chip one-time programmable (OTP) memory, external SPI ROM, or SMBus interfaces. Advanced features such as PortSwap, PHYBoost, and VariSense help simplify PCB routing and optimize USB signal integrity.
The controller also supports USB Link Power Management (LPM), configurable downstream port controls, and low-power operation, making it suitable for computer peripherals, docking stations, embedded systems, and multifunction USB devices.
Housed in a compact 56-pin VQFN (7 × 7mm) surface-mount package, the USB5744T/2G supports high-density PCB designs and automated SMT assembly. This specific ordering version operates over the commercial temperature range of 0°C to +70°C and is supplied in tape-and-reel packaging.
