General Description
Benefits and Features
TheMAX14600–MAX14605arethird-generationUSB2.0host
charger identification devices that combine USB Hi-Speed
analog switches with a USB adapter emulator circuit.
S Improved Charger Interoperability
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 devices support pass-through 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 have an nFET open-drain output (CEN) to
restart the peripheral connected to the USB host.
S Greater User Flexibility
All the devices support the CDP and standard down-
stream port (SDP) charging during the active state (S0)
and support the dedicated charging port (DCP) charg-
ing during the standby state (S3/S4/S5). The MAX14603/
MAX14604/MAX14605 support remote wake-up in stand-
by mode. The MAX14602/MAX14605 offer backward-
compatible CDP emulation upgrade to the MAX14566E.
CB0 and CB1 Pins Control Multiple Automatic
and Manual Charger States
S High Level of Integrated Features
Supports Remote Wake-Up (MAX14603/
MAX14604/MAX14605)
Low-Capacitance USB 2.0 Hi-Speed Switch to
Change Charging Modes
Automatic Current-Limit Switch Control
The MAX14600–MAX14605 are available in an 8-pin
(2mm x 2mm) TDFN package, and are specified over the
-40NC to +85NC extended temperature range.
S Save Space on Board

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

Detailed Description
The MAX14600–MAX14605 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 4I(typ) on-resistance. DP
and DM can handle signals between 0V and 6V with any
supply voltage.
tal inputs, CB0 and CB1, for mode selection. For the
MAX14600/MAX14601/MAX14603/MAX14604, connect
CB0 and CB1 to a logic-level low voltage for autode-
tection 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 family features an internal
resistor-divider for biasing data lines to provide sup-
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 2). 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.
-
port for Apple compliant devices. When the MAX14600–
MAX14605 family is not operated with the resistor-divider,
the device disconnects the resistor-dividers from the sup-
ply voltage to minimize supply current requirements. The
resistor-dividers are not connected in pass-through mode.

Autodetection
The MAX14600–MAX14605 family features autodetection
charger mode for dedicated chargers and USB masters.
Both CB0 and CB1 must be set low to activate autodetec-
tion charger mode.
Auto Peripheral Reset
The MAX14600–MAX14605 family features an auto cur-
rent-limit switch-control output. This feature resets the
peripheral connected to V
in the event the USB host
BUS
switches to or from standby mode. CEN 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, 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 (typ) threshold, the internal switch discon-
nects DM and 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.
USB Pass-Through Mode
with CDP Emulation
The MAX14600–MAX14605 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
Once the charging voltage is removed, the short between
DP and DM is disconnected for normal operation.

Data Contact Detect Support
The MAX14600–MAX14605 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.

Remote Wake-Up Support
The MAX14603/MAX14604/MAX14605 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 MAX14600 maintains
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
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents test
methodology and results.
Extended ESD Protection
(Human Body Model)
ESD-protection structures are incorporated on all pins
to protect against electrostatic discharges up to Q2kV
(Human Body Model) encountered during handling and
assembly. The ESD structures withstand high ESD both
in normal operation and when the device is powered
down. After an ESD event, the device continues to func-
tion without latchup (Figure 7a and Figure 7b).
