OUTPUT ASSERTION CONDITIONS
1 = PO7/PO5 assertion depends on IN1 undervoltage threshold (Table 2).
1 = PO7/PO5 assertion depends on IN2 undervoltage threshold (Table 3).
1 = PO7/PO5 assertion depends on IN3 undervoltage threshold (Table 4).
1 = PO7/PO5 assertion depends on IN4 undervoltage threshold (Table 4).
1 = PO7 (MAX6874 only) assertion depends on IN5 undervoltage threshold (Table 4). Must be
set to 0 for the MAX6875.
1 = PO7 (MAX6874 only) assertion depends on IN6 undervoltage threshold (Table 4). Must be
set to 0 for the MAX6875.
1 = PO7/PO5 assertion depends on watchdog (Tables 18 and 19).
Must be set to 0.
Must be set to 0.
1 = PO7/PO5 assertion depends on GPI1 (Table 5).
1 = PO7/PO5 assertion depends on GPI2 (Table 5).
1 = PO7/PO5 assertion depends on GPI3 (Table 5).
1 = PO7/PO5 assertion depends on GPI4 (Table 5).
1 = PO7 (MAX6874 only) assertion depends on PO1 (Table 7). Must be set to 0 for the MAX6875.
1 = PO7 (MAX6874 only) assertion depends on PO2 (Table 8). Must be set to 0 for the MAX6875.
1 = PO7/PO5 assertion depends on PO3 (MAX6874)/PO1 (MAX6875) (Table 9).
1 = PO7/PO5 assertion depends on PO4 (MAX6874)/PO2 (MAX6875) (Table 10).
1 = PO7/PO5 assertion depends on PO5 (MAX6874)/PO3 (MAX6875) (Table 11).
1 = PO7/PO5 assertion depends on PO6 (MAX6874)/PO4 (MAX6875) (Table 12).
1 = PO7 (MAX6874 only) assertion depends on PO8 (Table 14). Must be set to 0 for the MAX6875.
1 = PO7 asserts when MR = low (Table 6).
Table 13 only applies to PO7 of the MAX6874 and PO5
of the MAX6875. Write a 0 to a bit to make the PO7/PO5
output independent of the respective signal (IN_
thresholds, WD, GPI1–GPI4, MR, or other programma-
ble outputs).
