• Description: Power Switch ICs - USB
• Manufacturer: Maxim Integrated

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.
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 family features an auto cur-
rent-limit switch-control output. This feature resets the
peripheral connected to V
switches to or from standby mode. CEN or CEN provide
a 2s (typ) pulse on the rising or falling edge of CB0

case of CB0 and CB1 transition from 11 to 00 as long
as the peripheral remains connected. See the

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
