The STOTG04 is a USB On-The-Go full-speed transceiver. It provides complete physical layer (PHY) solution for any USB-OTG device. It contains VBUS charge pump and comparators, ID line detector and interrupt generator, and the USB differential driver and receivers. The STOTG04 transceiver is suitable for mobile and battery powered devices because of its low power consumption and power-down operating mode. The transceiver is capable of operation in several different modes. It can operate simultaneously in USB, I2C, UART and Audio modes.
The STOTG04E is a USB On-The-Go (USB-OTG) full-speed transceiver designed to provide a complete physical layer solution for mobile and battery-powered devices. It supports four operating modes: USB, UART, I2C, and Audio, with behavior configurable via an I2C serial interface.
Key features include support for 12Mbit/s full-speed and 1.5Mbit/s low-speed operations, integrated pull-up/down resistors, and +6kV ESD protection on USB pins. The device includes a voltage regulator, ID line detector, interrupt generator, and differential drivers/receivers.
