Interface - Controllers

Interface controllers are specialized computers typically used to provide an interface between a user and a software program or a user and another user(s). Modern interface controllers are increasingly becoming miniature computers capable of data storage, remote monitoring and even providing sophisticated control functions. Interface controllers like the USB5806T-I/KD can connect with other computers, commonly called host controllers, to enable communication and control of data and applications.

USB5806T-I/KD Application Field

The USB5806T-I/KD is an USB hub controller with integrated power switching. It is ideal for applications that require multiple USB ports, but have limited board space. The product is designed to fit into smart phones, tablets, set-top boxes, various embedded systems, and industrial control systems. In addition, it supports USB 2.0 devices and is ideal for device charging and control applications.

With integrated power control and Hi-Speed USB hub processing capabilities, it enables efficient and reliable control of USB devices. It is also capable of supplying up to two high-level power switches with protection against over- current and short-circuit situations. This makes the USB5806T-I/KD perfect for industrial control applications where a wide variety of USB host controllers need to be connected with safety.

USB5806T-I/KD Working Principle

The USB5806T-I/KD consist of two main components: a Hub controller and a power switching IC. The USB hub controller consists of an I/O port and a multiplexer, which can detect the insertion and removal of USB devices. The controller then reads and writes data to the hub RAM and transfers it to the host controller. The power switching IC allows for control of multiple power domains for either USB 2.0 or USB 3.0 power chains.

The Hub controller handles the standard USB commands, including HUB class and HUB feature descriptors. These commands enable the USB5806T-I/KD to manage a total of seven ports with SPI data rate up to 12Mb/s and I/O data rate up to 480Mb/s. It also incorporates support for multi-level Suspend and Resume controls, allowing for deeper power savings.

The power switching IC allows the USB5806T-I/KD to enable or disable individual power switches in the system. This allows users to separately turn on or turn off power to the connected USB devices. This is particularly useful for industrial applications where the connected device needs to be monitored or disconnected at certain times.

In addition to the power switching IC, the USB5806T-I/KD also incorporates power protection circuits. These circuits are designed to protect connected devices from over-voltage, over- current and short-circuit events. This ensures the safety of the connected devices and the entire system.

Overall, the USB5806T-I/KD is a highly versatile USB hub controller with integrated power switching capabilities. It is suitable for a wide variety of applications, including smart phones, tablets, set-top boxes, embedded systems, and industrial control systems. It also features power protection circuits and multi-level Suspend and Resume controls. The USB5806T-I/KD is a powerful and reliable hub controller for any USB application.
