General Description
The MAX3301E/MAX3302E fully integrated USB On-theGo (OTG) transceivers and charge pumps allow mobile devices such as PDAs, cellular phones, and digital cameras to interface directly with USB peripherals and each other without the need of a host PC. Use the MAX3301E/MAX3302E with an embedded USB host to directly connect to peripherals such as printers or external hard drives.
The MAX3301E/MAX3302E integrate a USB OTG transceiver, a VBUS charge pump, a linear regulator, and an I2C-compatible, 2-wire serial interface. An internal level shifter allows the MAX3301E/MAX3302E to interface with +1.65V to +3.6V logic supply voltages.
