Discharged Battery Latch is set, the state table is sus-
pended, the MAX1773/MAX1773A are not allowed to
switch batteries, and the Low Battery Latch is cleared.
The Discharged Battery Latch is cleared when both
batteries are above V
ACDET,
in the AC Adapter States
mode, and in the Startup States mode.
Startup States
When V
ACDET
rises at startup, the MAX1773/
MAX1773A use Startup States. See Table 3 for a
detailed listing of the MAX1773/MAX1773A states in
this mode. Note that once ACDET rises above 2.2V, the
MAX1773/MAX1773A are no longer in the Startup
Power Source Selector for
Dual-Battery Systems
