Over current level 1 voltage ( V
OC1
) is used to
monitor the amount of discharge current. If the
discharge current is high enough to cause VN pin
voltage increase to a value greater than V
OC1
, the
output of D
out
pin will switch to a low level
after a delay time t
OC1
. If the load is removed
from battery pack, the output of D
out
will
change to a high level again.
The mechanism of short circuit protection is
identical to a discharge current. If the short
circuit current is high enough to cause VN pin
voltage increase to greater than V
short
, the output
of D
out
pin will move to the low level after a
delay time t
short
, and the output of D
out
level
will change to high when the load is removed
from battery pack.
