General Description

The MAX3353E I2C™-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 D-

required for a dual-role device.

The MAX3353E integrates a regulated charge pump,

switchable pullup/pulldown resistors, and an I2C-com-

patible 2-wire serial interface. The device provides a

detector to monitor ID status and operates with logic

supply voltages (VL) between +1.65V and VCC and

charge-pump supply voltages (VCC) from +2.6V to

+5.5V. The charge pump supplies an OTG-compatible

output on VBUS while sourcing 8mA output current.

The MAX3353E enables USB OTG communication

between digital logic parts that cannot supply or tolerate

the +5V VBUS levels that USB OTG requires. By control-

ling and measuring VBUS using internal comparators,

this device supports USB OTG session request protocol

(SRP) and host negotiation protocol (HNP).

The MAX3353E has built-in ±15kV ESD protection circuitry

to guard VBUS, ID_IN, D+, and D-. The MAX3353E is

available in a 5 x 4 chip-scale package (UCSP™) and

16-pin TSSOP package.
