www.DataSheet4U.com 19-2845; Rev 1; 10/03 USB On-the-Go Charge Pump with Switchable Pullup/Pulldown Resistors General Description The MAX3353E I 2 C™-compatible USB On-The-Go (OTG) regulated charge pump with switchable pullup/pulldown resistors allows peripherals and mobile devices such as PDAs, cellular phones, and digital cameras to be interconnected without a host PC. The MAX3353E enables a system with an integrated USB dual-role transceiver to function as a USB OTG dual-role device. The charge pump in the MAX3353E supplies VBUS power and signaling that is required by the transceiver as defined in On-The-Go Supplement: USB 2.0, Revision 1.0. The MAX3353E provides the switchable pullup and pulldown resistors on D+ and Drequired for a dual-role device.
