by the USB device. This feature guarantees appropri-
ate 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/MAX14618 fea-
ture 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 con-
nected 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 V_BUS as it moves into the standby state.
Backward Compatibility
The MAX14602/MAX14605 offer easy backward-com-
patible CDP emulation upgrade to the MAX14566E.
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).
