Max3301e usb on-the-go transceiver and charge pump, General description, Applications
General Description
The MAX3301E fully integrated USB On-the-Go (OTG)
transceiver and charge pump allows 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 with
an embedded USB host to directly connect to peripher-
als such as printers or external hard drives.
The MAX3301E integrates a USB OTG transceiver, 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 to interface with logic sup-
ply voltages from +1.65V to +3.6V. The MAX3301E’s
OTG-compliant charge pump operates with +3V to
+4.5V input supply voltages, and supplies an OTG-com-
patible output on V
BUS
while sourcing more than 8mA of
output current.
The MAX3301E enables USB OTG communication from
highly integrated digital devices that cannot supply or tol-
erate the +5V V
BUS
levels that USB OTG requires. The
device supports USB OTG session-request protocol
(SRP) and host-negotiation protocol (HNP) by controlling
and measuring V
BUS
using internal comparators.
The MAX3301E provides built-in ±15kV electrostatic-
discharge (ESD) protection for the V
BUS
, ID_IN, D+,
and D- terminals. The MAX3301E is available in 5 x 5
chip-scale (UCSP™) and 32-pin (5mm x 5mm x 0.8mm)
thin QFN packages and operates over the extended
-40
°C to +85°C temperature range.
