Note 6: Minimum and maximum limits are guaranteed but may not be 100% tested.
Note 7: These supply voltages are calculated using the I
VPPSENSE
and I
VNNSENSE
values shown in the Electrical
Characteristics table. The typical voltage values shown are calculated using a R
VPP
and R
VNN
values without
any tolerance variation. The minimum and maximum voltage limits shown include either a +1% or –1% (+1%
for Over-voltage turn on and Under-voltage turn off, -1% for Over-voltage turn off and Under-voltage turn on)
variation of R
VPP
or R
VNN
off the nominal 402kohm and 1.2Mohm values. These voltage specifications are
examples to show both typical and worst case voltage ranges for the given R
VPP
and R
VNN
resistor values.
Please refer to the Application Information section for a more detailed description of how to calculate the over
and under voltage trip voltages for a given resistor value.
