Additionally, the battery as a whole can be undervoltage (UV),
where V

< V
UVL
. Note that this final condition is not
necessarily
(though normally) mutually exclusive with the
other cell conditions: if one cell were at 0V, the other cell could
be in NO, and the battery could still be in UV.
The charger can be either present (ON) or not present (OFF);
the “X” in the table means the condition is true regardless of the
state of the charger. The load current can be either 0, normal
(0 < I
LOAD
< I
ILIMIT
) or a short (I

< I

) where I

is
set by V

; the “X” in the table refers to a load
current that can be either 0 or normal. Finally, the switch can
be either ON, OFF, or cycling at either 1/8 or 7/8 duty cycle,
where the duty cycle refers to the portion of the period when
the switch is on; the notation On
>On simply means that the
switch does not change state, it remains on; the notation
>Off
means that the switch turns off regardless of its previous state.
