Description
The STOTG04ES is a USB On-The-Go full-speed
transceiver. It provides complete physical layer
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 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.
