It is quite typical to monitor the current through
a component or a voltage on a node to regulate
an input. Some applications may find it more
useful, however, to monitor the power through a
transistor. One such occasion would be in charging
a battery. When the voltage is low, the designer
may want more current charging, but as
the voltage increases, the current could decrease,
ultimately saving charging time and power.
