Description
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 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.
