The MAX14600–MAX14605 and MAX14618 adapter
emulator family has Hi-Speed USB analog switches that
support USB hosts to identify the USB port as a charger
port when the USB host is in a low-power mode and
cannot enumerate USB devices. These Hi-Speed USB
switches feature low 4pF (typ) on-capacitance and low
3.5I (typ) on-resistance. DP and DM can handle signals
between 0V and 6V with any supply voltage.
The MAX14600–MAX14605/MAX14618 family features
an internal resistor-divider for biasing data lines to pro-
vide support for Apple
MAX14600–MAX14605/MAX14618 family is not oper-
ated with the resistor-divider, the device disconnects
the resistor-dividers from the supply voltage to minimize
supply current requirements. The resistor-dividers are not
connected in pass-through mode.

The MAX14600–MAX14605/MAX14618 family features
dual digital inputs, CB0 and CB1, for mode selection.
For the MAX14600/MAX14601/MAX14603/MAX14604,
connect CB0 and CB1 to a logic-level low voltage for
autodetection charger mode (AM). Change only CB1 to a
logic-level high for forced dedicated charger mode (FM).
Change only CB1 to a logic-level low for normal high-
speed pass-through mode (PM). Connect CB0 and CB1
to a logic-level high for high-speed pass-through mode
with CDP emulation (CM). See
For the MAX14618, connect CB0 to a logic-level low volt-
age for autodetection charger mode (AM). Change CB0
to a logic-level high voltage and CB1 to a logic-level low
voltage to place the MAX14618 in normal high-speed
pass-through charger mode (PM). Connect CB0 and
CB1 to a logic-level high for high-speed pass-through
mode with CDP emuation (CM). See
In CDP emulation mode, the peripheral device with
CDP detection capability draws the charging current
