LTC4410
APPLICATIO S I FOR ATIO
Dual Battery Charging with Priority
The LTC4410 can be used to manage two battery chargers,
giving one of the chargers (see Figure 2) priority. When
BAT1 is being charged, the charge current is flowing
through the LTC4410. The LTC4410 is sensing the current
and sourcing a current equal to BAT1 charge current/1000
out of CHP. This effectively reduces the BAT2 charger
current. As BAT1 current demands reduce, the current
sourced out of CHP is reduced, enabling BAT2 to have
more current. In this example the power supply is a 750mA
minimum wall adapter, R PROG (R2 and R3) for the charg-
ers are 2k ? , resulting in a 750mA charge current. In this
application, the total current out of the wall adapter will
never exceed 750mA.
