Note 6: Minimum and maximum limits are guaranteed but may not be 100% tested.
Note 7: 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 a RVPPSENSE and RVNNSENSE
value of 422kohm 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 RVPPSENSE or RVNNSENSE off the nominal 422kohm and 392kohm
values. These voltage specifications are examples to show both typical and worst case voltage ranges for a
given RVPPSENSE and RVNNSENSE resistor values of 422kohm and 392kohm. 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.
Note 8: The fact that the over-voltage turn on specifications exceed the absolute maximum of +/-70V for
the TA3020 does not imply that the part will work at these elevated supply voltages. It also does
not imply that the TA3020 is tested or guaranteed at these supply voltages. The supply voltages
are simply a calculation based on the process spread of the IVPPSENSE and IVNNSENSE
currents (see note 7). The supply voltage must be maintained below the absolute maximum of
+/-70V or permanent damage to the TA3020 may occur.
