The MAX3421EETJ+T provides a full-featured USB host transceiver function, including low speed (1.5 Mbps) and high speed (12 Mbps). The device also has on-chip detection and power management functions, and supports over-current detection. Furthermore, the user can also use the MAX3421EETJ+T to access serial and parallel ports, as well as additional functions such as I2C and SPI.

The working principle of the MAX3421EETJ+T is very simple. When USB devices such as printers, keyboards, scanners, digital cameras, and so on are connected to the USB host, the USB host sends a message to the MAX3421EETJ+T. The MAX3421EETJ+T then sends a signal to the USB device to enable or disable it. After that, the MAX3421EETJ+T will detect the data or commands which are being sent by the USB device and then send them to the USB host. On the other hand, the MAX3421EETJ+T will also detect the data or commands which are being sent by the USB host and then send them to the USB device. In this way, the MAX3421EETJ+T is able to link the USB host and the USB device.

The MAX3421EETJ+T has many application fields, such as, the automotive field. Automotive systems need to communicate with external USB devices, such as USB flash drives, for various purposes. In this case, the MAX3421EETJ+T can be used to provide the necessary hook up between the USB device and the system. It performs all the necessary tasks, such as detecting the presence of USB devices, identifying data signals, and controlling power and data flow.
