USB On-the-Go Transceivers and Charge Pumps
General Description
The MAX3301E/MAX3302E fully integrated USB On-the-
Go (OTG) transceivers and charge pumps allow mobile
devices such as PDAs, cellular phones, and digital
cameras to interface directly with USB peripherals and
each other without the need of a host PC. Use the
MAX3301E/MAX3302E with an embedded USB host to
directly connect to peripherals such as printers or
external hard drives.
The MAX3301E/MAX3302E integrate a USB OTG trans-
ceiver, a V
BUS
charge pump, a linear regulator, and an
I
2
C-compatible, 2-wire serial interface. An internal level
shifter allows the MAX3301E/MAX3302E to interface
with +1.65V to +3.6V logic supply voltages. The
MAX3301E/MAX3302E’s OTG-compliant charge pump
operates with +3V to +4.5V input supply voltages, and
supplies an OTG-compatible output on V
BUS
while
sourcing more than 8mA of output current.
The MAX3301E/MAX3302E enable USB OTG communi-
cation from highly integrated digital devices that cannot
supply or tolerate the +5V V
BUS
levels that USB OTG
requires. The device supports USB OTG session-request
protocol (SRP) and host-negotiation protocol (HNP).
The MAX3301E/MAX3302E provide built-in ±15kV elec-
trostatic-discharge (ESD) protection for the V
BUS
, ID_IN,
D+, and D- terminals. The MAX3301E/MAX3302E are
available in 25-bump chip-scale (UCSP™), 25-bump
WLP package, 28-pin TQFN, and 32-pin TQFN pack-
ages and operate over the extended -40°C to +85°C
temperature range.

UCSP bumps are in a 5 x 5 array. The UCSP package size is
2.5mm x 2.5mm x 0.62mm. Requires solder temperature profile
described in the Absolute Maximum Ratings section. UCSP reli-
ability is integrally linked to the user’s assembly methods, circuit
board material and environment. See the UCSP Applications
Information section of this data sheet for more information.

Note 1:
The UCSP package is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the
device can be exposed to during board-level solder attach and rework. This limit permits only the use of the solder profiles recom-
mended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and convection reflow. Preheating is
required. Hand or wave soldering is not allowed.
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.
