(AM) or connect CB1 to a logic-level high for forced  
dedicated-charger mode (FM).  
from the resistor-divider and DP and DM are shorted  
together for dedicated charging mode.  
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.  
Autodetection  
All the devices feature autodetection charger mode for  
dedicated chargers and USB masters. CB must be set  
low to activate autodetection charger mode.  
Once the charging voltage is removed, the short between  
DP and DM is disconnected for normal operation.  
In autodetection charger mode, the MAX14566E moni-  
tors the voltages at DM and DP to determine the type of  
the device attached. If the voltage at DM is +2.3V (typ)  
or higher and the voltage at DP is +2.3V (typ) or lower,  
the voltage stays unchanged.  
Automatic Peripheral Reset  
The MAX14566E/MAX14566AE feature automatic current-  
limit switch control output. This feature resets the peripher-  
al connected to V  
in the event the USB host switches to  
BUS  
If the voltage at DM is forced below the +2.3V (typ)  
threshold, the internal switch disconnects DM and DP  
or from standby mode. CEN/CEN provide a 1s (typ) pulse  
on the rising or falling edge of CB (Figures 4, 5, and 6).
