It operates from dual supply rails: a core rail at 1.08V to 1.32V and an I/O rail at 3V to 3.6V, which means your board needs two regulated voltages — the core rail is tight, so a 1.2V LDO with ±2% tolerance covers it. The 100-VFQFN exposed-pad package (12x12 mm) demands a thermal via pattern under the paddle for heat sinking; the datasheet's recommended footprint is non-negotiable if you want the junction temperature to stay within the 0°C to 70°C commercial range. ## Sourcing and lifecycle status It is ROHS3 compliant. Available in Tape & Reel or Cut Tape; the Cut Tape option suits prototype and small-run builds without committing to a full reel. ## How it compares to the USB2517-JZX The USB2517-JZX is a USB 2.0-only hub controller in a similar 100-pin package, but it lacks USB 3.1 support and the I²C/SMBus/SPI/UART management interface that the USB5926CT/KD provides. If your design needs USB 3.1 SuperSpeed ports or out-of-band configuration via SPI/UART, the USB5926CT/KD is the correct part; the USB2517-JZX only covers USB 2.0 and uses a pure USB interface.","metaTitle":"USB5926CT/KD Hub Controller – Microchip, USB 3.1","metaDescription":"USB5926CT/KD Hub Controller from Microchip.
