SMBus Level 2 Battery Charger
with Remote Sense
command. The charge current-regulation loop is in con-
trol as long as the selected battery voltage is below the
charge voltage set point. When the selected battery
voltage reaches its set point, the voltage-regulation
loop takes control and maintains the battery voltage at
the set point. A third loop (CCS) takes control and
reduces the charge current when the adapter current
exceeds the input current limit set by the InputCurrent()
command.
A functional diagram is shown in Figure 2.
