USB 3.1 hub controllers

9 November 2016 Telecoms, Datacoms, Wireless, IoT

New from Microchip are the USB58xx and USB59xx families of seven-port USB 3.1 Gen1 hub ICs, offering manufacturers multiple direct interfaces to USB Type-C connectors for enabling 5 Gbps USB data rates in a single integrated circuit.

The devices are ideal for applications such as monitors, docking stations, digital televisions, set-top boxes and computing peripherals. Having a hub IC that supports seven ports avoids the power and cost problem of tiering two four-port devices to provide sufficient downstream ports for end-customer applications. In addition, Microchip’s proprietary SmartHub technology can further reduce bill of materials (BOM) cost by enabling I/O bridging and FlexConnect for expanded USB hub functionality without adding any additional components.

Microchip enables multiple, direct USB Type-C connections through integrated 2:1 multiplexers which support the reversible connection feature of the USB Type-C connector. In addition, the devices can expand beyond seven ports through PortSplitting, which allows embedded applications to only use the interface needed for their internal USB connection.

Each device also has built-in Billboard support for notifying users when an unsupported device has been connected in a USB Power Delivery application. In addition, the USB58xx and USB59xx families are supported by Microchip’s USBCheck, a free engineering service for reviewing schematics and layout designs.

The USB59xx family supports direct upstream interface of USB Type-C, while the USB58xx provides support for legacy, non-USB Type-C interfaces. Both families support legacy battery charging including BC1.2, Apple devices and many non-standard devices available in the market today.

The USB58xx and USB59xx families are available for sampling and volume production now. The USB58xx family features four devices whilst the USB59xx family features three devices. Both families are available in 100-pin QFN packages in industrial and automotive grades.
