Note 6: These supply voltages are calculated using the IVPPSENSE and IVNNSENSE values shown in the
Electrical Characteristics table. The typical voltage values shown are calculated using RVPP and
RVNN 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 for RVPP1 or RVNN1 off the nominal 576kΩ
value. These voltage specifications are examples to show both typical and worst case voltage
ranges for the given RVPP and RVNN 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.
