STOTG04ESQTR STMicroelectronics

STOTG04ES USB-OTG Full-speed Transceiver Feature summary Meets the requirements of the universal serial bus specification revision 2.0 And the on-the- go supplement to the USB 2.0 specification Analog car kit-compatible Three operating modes: USB, UART and audio QFN24 (4mmx4mm) 2 Configurable using I C serial interface Capable of 12Mbit/s full-speed and 1.5Mbit/s low-speed modes of operation MP3 players Standard digital interface compliant with the Digital cameras OTG transceiver specification Printers Supports the session request protocol (SRP) and host negotiation protocol (HNP) Description 35mA Typical V Charge pump output BUS current for 3.3V supply voltage The STOTG04ES is a USB On-The-Go full-speed Ability to control external charge pump for transceiver. It provides complete physical layer higher V currents solution for any USB-OTG device. It contains BUS V charge pump and comparators, ID line BUS Integrated pull-up/-down resistors detector and interrupt generator, and the USB 6kV ESD protection on all USB pins (contact differential driver and receivers. The STOTG04 discharge) transceiver is suitable for mobile and battery powered devices because of its low power +1.6V to +3.6V Digital power supply and +2.7V consumption and power down operating mode. to +5.5V analog supply voltage range Power-down mode with very low power The transceiver is capable of operation in several consumption for battery powered devices different modes. It can operate in basic USB-OTG mode, as an UART transceiver or in audio mode. Ideal for system ASICs with built-in USB OTG Behavior of the transceiver is fully configurable dual role core 2 through the two-wire IC serial bus. The Available In QFN-24 transceiver supports session request protocol and 40C to +85C operating temperature range host negotiation protocol.
