FUNCTION
Power-Supply Input. V CC input range is +2.6V to +5.5V. Bypass V CC to GND with a 1μF capacitor.
Logic Supply. V L sets the logic output high voltage and logic input high threshold for SDA, SCL,
INT , and ID_OUT. V L can range from +1.65V to V CC . Bypass V L to GND with a 0.1μF capacitor.
Serial Data Input/Output. I 2 C bus serial data input/open-drain output can be driven above V L .
Address Select Input. Address selection for the I 2 C-compatible interface. ADD has an internal
110k Ω pulldown resistor (see the 2-Wire I 2 C Compatible Serial Interface section for details).
Serial Clock Input. I 2 C bus serial clock input. Can be driven above V L .
Interrupt Output. INT is an active-low output and can be set either open-drain or push/pull output
through control register 1 (default = open drain).
Device ID Output. Output of ID_IN level translated to V L .
Termination Supply Input. Connect +3V to +3.6V supply voltage for internal USB pullup resistors.
Bypass V TRM to GND with a 0.1μF capacitor.
USB D- (±15kV ESD Protected)
USB D+ (±15kV ESD Protected)
Device ID Input. Internally pulled up to V CC . ID_IN logic state is V L level translated to ID_OUT and
can be read through the I 2 C interface (±15kV ESD protected).
No Connection. Not internally connected.

Charge-Pump Capacitor Negative Connection
Charge-Pump Capacitor Positive Connection
OTG Bus Supply. Provides power to the bus. V BUS can be back-driven to +6V. Bypass V BUS to
GND with a 1μF capacitor.
Detailed Description
The MAX3353E integrates a regulated charge pump,
switchable pullup/pulldown resistors, and an I 2 C-
compatible 2-wire serial interface. The internal level
shifter allows the device to operate with logic supply volt-
ages (V L ) between +1.65V and V CC . The MAX3353E’s
OTG-compliant charge pump operates with input supply
voltages (V CC ) from +2.6V to +5.5V and supplies an
OTG-compatible output on V BUS while sourcing 8mA
output current.
The MAX3353E level-detector comparators monitor impor-
tant V BUS voltages needed to support SRP and HNP and
provides an interrupt output signal for OTG events that
require action. The V BUS power-control block performs the
various switching functions required by an OTG dual-role
device and is programmable by system logic.
For OTG operation, D+ and D- are connected to switch-
able pulldown resistors (host) and switchable pullup
resistors (peripheral) controlled by internal registers.
Charge Pump
The MAX3353E’s OTG-compliant charge-pump operates
with input supply voltages (V CC ) from +2.6V to +5.5V
and supplies an OTG-compatible output on V BUS with
the capability of sourcing 8mA (min) output current.
When V BUS is not providing power, an input impedance
of no more than 100k Ω and no less than 40k Ω to GND is
present on V BUS . When V BUS provides power, the rise
time on V BUS from 0 to 4.4V is no longer than 100ms
when driving a constant current load of 8mA and an
external load capacitance of 13μF.
During a continuous short circuit on V BUS , the charge-
pump output is current limited to 140mA (typ). Thermal-
shutdown circuitry turns off the charge pump if the die
temperature exceeds +150°C and restarts when the die
cools to 140°C.
Level Shifters
Internal level shifters allow the system-side interface to
run at logic supply voltages as low as 1.65V. Interface
logic signals are referenced to the voltage applied to V L .
