Figure 2. Typical Application Circuit Using Separate DC and USB Connectors
for two-input or single-input operation. Figure 2 is the
typical application circuit using separate DC and USB
connectors. Figure 3 is the typical application circuit
using a Mini 5-style connector or other DC/USB com-
mon connector.
In addition to charging the battery, the MAX8677C also
supplies power to the system through the SYS output.
The charging current is also provided from SYS so that
the set input current limit controls the total SYS current,
which is the sum of the system load current and the
battery-charging current. SYS is powered from either
the DC input pin or the USB input pin. If both the DC
and USB are connected, DC takes precedence.
