Power Management
The bidirectional capability of the MAX4081 makes it an
excellent candidate for use in smart battery packs. In
the application diagram (Figure 5), the MAX4081 moni-
tors the charging current into the battery as well as the
discharge current out of the battery. The microcon-
troller stores this information, allowing the system to
query the battery's status as needed to make system
power-management decisions.
