up to 1.5A immediately without USB enumeration. The
MAX14602/MAX14605 have CB0 digital input control
only
compatible with the MAX14566E, and CB0 and CB1
are connected together internally, which makes these
devices easy upgrades for CDP emulation.
The MAX14600–MAX14605/MAX14618 family features
autodetection charger mode for dedicated chargers and
USB masters. Both CB0 and CB1 must be set low to acti-
vate autodetection charger mode.
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.
Once the charging voltage is removed, the short between
DP and DM is disconnected for normal operation.
The MAX14600–MAX14605/MAX14618 family features
an auto current-limit switch-control output. This feature
resets the peripheral connected to V
the USB host switches to or from standby mode. CEN or
CEN provide a 2s (typ) pulse on the rising or falling edge
of CB0
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 con-
nected. See the
more information.
