Product details

Active USB 3.1 hub controller for industrial-temperature designs

The USB5916CT-I/KD: It supports both USB 2.0 and USB 3.1 standards, so it can handle SuperSpeed (5 Gbps) traffic alongside legacy full-speed devices on the same downstream ports.

Package and supply rails that shape the board layout

Housed in a 100-VFQFN with exposed pad (12x12 mm body), the USB5916CT-I/KD demands a solid thermal via array under the centre pad — the datasheet's recommended footprint is the starting point, not a suggestion. The dual supply range (1.08V–1.32V core, 3V–3.6V I/O) means two independent power planes; a single 3.3V rail alone will not power the core. The I²C, SMBus, SPI, and UART interfaces give the host processor flexible control for port mapping, over-current reporting, and firmware updates without tying up a dedicated USB port.

Frequently asked questions

Does the USB5916CT-I/KD support USB 3.1?

Yes — the USB5916CT-I/KD is listed with both USB 2.0 and USB 3.1 standards. That means it can route SuperSpeed (5 Gbps) traffic on the upstream and downstream ports, while remaining backward-compatible with USB 2.0 and USB 1.x devices.
