4.4.1.1
In serial path configuration, the current path used for charging the battery is the same as the supply path
from charger to radio B+. Refer to the block diagram example in
Transistors M1 and M2 control the charge current and provide a voltage clamping function in case of no
battery or in case of a dead battery to allow the application to operate. In both cases transistor M3 is
non-conducting and the battery is charged with a trickle charge current internal to the MC13783. The
transistor M3 is conducting in case the battery has to be connected to the application like for normal
operation or for standalone trickle charging. Transistor M2 is non-conducting in case the charger voltage
is too high. A current can be supplied from the battery to an accessory by having all transistors M1, M2
and M3 conducting.
