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 VBUS charge pump, a linear regulator, and an
I2C-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 VBUS 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 VBUS 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 VBUS, 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.
