The MAX3353E I
regulated charge pump with switchable pullup/pull-
down 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 V
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 I
patible 2-wire serial interface. The device provides a
detector to monitor ID status and operates with logic
supply voltages (V
charge-pump supply voltages (V
+5.5V. The charge pump supplies an OTG-compatible
output on V
The MAX3353E enables USB OTG communication
between digital logic parts that cannot supply or tolerate
the +5V V
ling and measuring V
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 V
available in a 5 x 4 chip-scale package (UCSP™) and
16-pin TSSOP package.
