MAX3355EEUD+T

P1-P3P4-P6P7-P9P10-P11
General Description
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.
The MAX3355E’s internal charge pump supplies V
BUS
power and signaling that is required by the transceiver as
defined in On-the-Go Supplement to the USB 2.0
Specification, Revision 1.0. The MAX3355E features ID
detection and internal comparators for monitoring
V
BUS
. The V
BUS
status outputs are used during negoti-
ation for the USB according to the session request pro-
tocol (SRP) and host negotiation protocol (HNP).
The MAX3355E operates with logic supply voltages
(V
L
) as low as 1.65V, ensuring compatibility with low-
voltage ASICs. The device also features a logic-selec-
table 1µA shutdown mode.
The MAX3355E has built-in ±15kV ESD-protection cir-
cuitry to protect the V
BUS
and ID_IN pins. The device is
available in a miniature 4 x 3 chip-scale package
(UCSP), as well as a 14-pin TSSOP package, and is
specified for operation over the -40°C to +85°C extended
temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
