    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
    and no less than 40k
    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
    .
