USB Host Charger Identification/
Adapter Emulators
General Description
Benefits and Features
● Improved Charger Interoperability
The MAX14600–MAX14605 and MAX14618 are third-
generation USB 2.0 host charger identification devices
that combine USB Hi-Speed analog switches with a USB
adapter emulator circuit.
• USB CDP Emulation in S0 State
• Meets New USB Battery Charging (BC) Revision
1.2 Specification
• Backward-Compatible with Previous USB BC Revisions
• Meets China YD/T1591-2009 Charging Specification
• Supports Standby Mode Charging for Apple and
BC Revision 1.2-Compatible Devices
The
MAX14600–MAX14605
and
MAX14618
support passthrough mode and auto mode. In charging
downstream port (CDP) pass-through mode, the devices
emulate the CDP function while supporting normal USB
traffic. The MAX14600/MAX14603/MAX14605 have a
pFET open-drain output (CEN), and the MAX14601/
MAX14604/MAX14618 have an nFET open-drain output
(CEN) to restart the peripheral connected to the USB host.
● Greater User Flexibility
• CB0 and CB1 Pins Control Multiple Automatic and
Manual Charger States
● High Level of Integrated Features
• Supports Remote Wake-Up (MAX14603/
MAX14604/MAX14605/MAX14618)
• Low-Capacitance USB 2.0 Hi-Speed Switch to
Change Charging Modes
• Automatic Current-Limit Switch Control
● Save Space on Board
All the devices support the CDP and standard downstream
port (SDP) charging during the active state (S0) and
support the dedicated charging port (DCP) charging
during the standby state (S3/S4/S5). The MAX14603/
MAX14604/MAX14605/MAX14618 support remote wakeup in
standby mode. The MAX14602/MAX14605 offer backward-
compatible CDP emulation upgrade to the MAX14566E.
• 2mm x 2mm, 8-Pin TDFN Package
Applications
● USB Host Data/Chargers including:
The MAX14600–MAX14605/MAX14618 are available in
an 8-pin (2mm x 2mm) TDFN package, and are specified
over the -40°C to +85°C extended temperature range.
• Laptop and Desktop Computers
• USB Hubs
• Flat-Panel Displays with USB
• Media Players

Detailed Description
The MAX14600–MAX14605/MAX14618 family features
dual digital inputs, CB0 and CB1, for mode selection.
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
3.5Ω (typ) on-resistance. DP and DM can handle signals
between 0V and 6V with any supply voltage.
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 Table 1.
Resistor-Dividers
The MAX14600–MAX14605/MAX14618 family features
an internal resistor-divider for biasing data lines to
provide support for Apple-compliant devices. When
the MAX14600–MAX14605/MAX14618 family is not
operated 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.
For the MAX14618, connect CB0 to a logic-level low voltage
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 Table 2.

USB Host Charger Identification/
Adapter Emulators
In CDP emulation mode, the peripheral device with CDP
detection capability draws the charging current up to 1.5A
immediately without USB enumeration. The MAX14602/
MAX14605 have CB0 digital input control only (Table 3).
The MAX14602/MAX14605 are pin-to-pin compatible with
the MAX14566E, and CB0 and CB1 are connected together
internally, which makes these devices easy upgrades for
CDP emulation.
DP from the resistor-divider and DP and DM are shorted
together for dedicated charging mode.
Also, if the voltage at DP is forced higher than the 2.3V
(typ) threshold, the internal switch disconnects DM and
DP from the resistor-divider and DP and DM are shorted
together for dedicated charging mode.
Once the charging voltage is removed, the short between
DP and DM is disconnected for normal operation.

or CEN provide a 2s (typ) pulse on the rising or
falling-edge of CB0 (Figure 4 and Figure 5.) With the
MAX14603/ MAX14604/MAX14605/MAX14618, the auto-
peripheral reset is suspended in case of CB0 and CB1
transition from 11 to 00 as long as the peripheral remains
connected. See the Remote Wake-Up Support section for
more information.
In autodetection charger mode, the device monitors the
voltages at DM and DP to determine the type of device
attached. If the voltage at DM is 2.05V (typ) or higher and
the voltage at DP is 2.3V (typ) or lower, the voltage stays
unchanged. If the voltage at DM is forced below the 2.05V

USB Pass-Through Mode with CDP Emulation
Table 4. Different Power States
The MAX14600–MAX14605/MAX14618 family features a
pass-through mode with CDP emulation. This is to support
the higher charging current capability during the pass-
through mode in normal USB operation (S0 state). The
peripheral device equipped with CDP detection capability
could draw a charging current as defined in USB Battery
Charger Specification 1.2 when the charging host supports
the CDP mode. This is a useful feature since most host
USB transceivers do not have the CDP function. Table 4
shows the different power states of S0–S5.

The

switch-control output can be used to discharge the V
feature remote wake-up if pass-through mode with CDP
emulation is used prior to transitioning to auto mode in
standby state (S3). If the peripheral device is connected and
remains in the USB port during S0 state, the MAX14603/
MAX14604/MAX14605/MAX14618 maintain the pass-
through mode until it is removed. If this feature is not
needed, such as in battery-powered mode, the embedded
control could cancel the remote wake-up by toggling the
BUS
during V
reset. When the system controls the current

limit switch for V
toggle, the output capacitor can

Data Contact Detect Support
The MAX14600–MAX14605/MAX14618 family support
USB devices that require detecting the USB data lines
prior to charging. When a USB Revision 1.2-compliant
device is attached, the USB data lines DP and DM are
shorted together. The short remains until it is detected
by the USB device. This feature guarantees appropriate
charger detection if a USB Revision 1.2-compliant device
is attached. The autodetection charger mode is activated
after the data contact detect is established. CB0 and CB1
must be set low to activate data contact detect support.
