with CB1. Connect CB1 to a logic-level low for auto mode
(AM) or connect CB1 to a logic-level high for forced
dedicated-charger mode (FM).
Autodetection
All the devices feature autodetection charger mode for
dedicated chargers and USB masters. CB must be set
low to activate autodetection charger mode.
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.
If the voltage at DM is forced below 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.
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.
Automatic Peripheral Reset
The MAX14566E/MAX14566AE feature automatic current-
limit switch control output. This feature resets the peripher-
al connected to VBUS in the event the USB host switches to
or from standby mode. CEN/CEN provide a 1s (typ) pulse
on the rising or falling edge of CB (Figures 4, 5, and 6).
