The TUSB2077APTG4 is a device interface controller with integrated USB 2.0 transceiver, power control and switch matrix. It allows you to control up to four peripheral devices (either a powered-only or automatically (bus-powered) device) connected to the host via USB. It is suitable for interfacing a wide range of products, from printers, scanners and digital cameras to digital video recorders.

The TUSB2077APTG4 provides an easy, low-cost way to interface and switch between up to four different USB devices using a single USB port. By supporting several different devices that can be connected to the computer through the same single USB port, the TUSB2077APTG4 helps reduce the complexity of the system and simplifies the job of connecting multiple devices.

The TUSB2077APTG4 supports the High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low Speed (1.5 Mbps) USB 2.0 interfaces. The TUSB2077APTG4 controller is an upgradable solution, meaning it can be reconfigured remotely via software. The device also provides a variety of power schemes including bus power, self-powered, and wake-up from suspend mode.

The TUSB2077APTG4 also supports seven different switching configurations to match different device configurations. This allows the user to connect one device or multiple devices together or use different combinations of power schemes. It has a built-in switching matrix that enables the TUSB2077APTG4 to efficiently manage the device connections and setting the dataflow protocols.

The TUSB2077APTG4 also provides advanced features such as over-current protection, wake-up from suspend mode, and auto-configuration to simplify the connection setup. It also supports several kinds of data transfer, including Bulk, Interrupt, and Isochronous transfers. In addition, it supports bus-powered peripheral devices and data transfer up to 20Mbps.

The application field of the TUSB2077APTG4 includes but not limited to computer peripherals, consumer electronics, and industrial control application. In some industrial control applications, multiple devices like servo motors, encoders, motion positioners, PLCs, etc. can be connected to the TUSB2077APTG4 and be linked to a single PC. It can also be used for connecting scanners, external disk drives and other USB devices to the host PC.

The working principle of the TUSB2077APTG4 is simple and straightforward. It transfers data to and from the connected USB devices using the USB Serial Interface (UART). When the connected USB device sends a request to the host, the TUSB2077APTG4 controller handles the request by convert into a descriptive protocol and send it to the host. It then forwards the incoming data from the host to any of the four ports on the TUSB2077APTG4. The TUSB2077APTG4 also controls the power supplied to the USB devices, allowing the host to switch the devices on and off, or adjust the amount of power supplied to them.

The TUSB2077APTG4 also offers robust error handling capabilities, as well as over-current protection, which prevents any damage from too much current passing through the device. This makes the TUSB2077APTG4 an ideal choice for applications that require multiple device connectivity, as well as for applications that require robust and reliable data exchange.

The TUSB2077APTG4 is a versatile device that has a wide application field and is capable of managing, switching, and controlling up to four different USB devices. With its integrated USB 2.0 transceiver, power control, and switch matrix, it is a great device for interfacing a wide array of products and simplifying the connection setup.
