General Description  
Features  
The MAX3355E integrates a charge pump and com-  
parators to enable a system with an integrated USB on-  
the-go (OTG) dual-role transceiver to function as a USB  
OTG dual-role device. USB OTG facilitates the direct  
connection of peripherals and mobile devices such as  
PDAs, cellular phones, MP3 players, and digital cam-  
eras to one another without a host PC.
