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
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).
