Forced Charger Modes
The MAX14640–MAX14644/MAX14651 can be config-
ured in different forced dedicated charging port (DCP)
modes; VBUS is enabled and DP and DM are either
shorted (FM) or connected to resistor-dividers (all other
modes). Table 6 summarizes the resistor-divider values
in each forced mode.
Automatic Detection with
Remote Wake-Up Support
The MAX14640–MAX14644/MAX14651 feature auto-
matic detection charger mode (AM1/AM2) for dedicated
chargers and USB masters. In automatic detection
charger mode, the device monitors the voltages on DM
and DP with resistor-dividers connected to determine
the type of device attached.
If a USB-compliant device is connected, DP and DM
are shorted together to commence charging. Once the
charging device is removed, the short between DP and
DM is disconnected and the resistor-divider is applied.
A pulldown resistor on the shorted DP/DM node ensures
that a disconnect is detected.
