AAT8641 Series
(Over-Discharge Release Voltage).
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 to be greater than V
OC1
, the output of
D
out
pin will switch to low level after a delay
time t
OC1
. If the load is removed from battery
pack, the output of D
out
will change to high
again.
The mechanism of short circuit protection is
exactly the same as discharge current. If the short
circuit current is high enough to cause VN pin
voltage to be greater than V
short
, the output of
D
out
pin would fall to 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.
