STOTG04EQTR

STOTG04EQTR is a USB on-the-go full-speed transceiver in a 24 pin QFN package. 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 in basic USB-OTG mode, as an I2C and UART transceiver, or in audio mode. Behavior of the transceiver is fully configurable through the two-wire I2C serial bus. The transceiver supports session request protocol and host negotiation protocol. The applications are mobile phones, PDAs, MP3 players, printers and digital cameras.
