OUTPUT ASSERTION CONDITIONS
1 = PO6/PO4 assertion depends on IN1 primary undervoltage threshold (Table 2).
1 = PO6/PO4 assertion depends on IN2 primary undervoltage threshold (Table 3).
1 = PO6/PO4 assertion depends on IN3 primary undervoltage threshold (Table 4).
1 = PO6/PO4 assertion depends on IN4 primary undervoltage threshold (Table 4).
1 = PO6 (MAX6872 only) assertion depends on IN5 primary undervoltage threshold (Table 4).
Must be set to 0 for the MAX6873.
1 = PO6 (MAX6872 only) assertion depends on IN6 primary undervoltage threshold (Table 4).
Must be set to 0 for the MAX6873.
1 = PO6/PO4 assertion depends on watchdog 1 (Tables 25 and 26).
1 = PO6/PO4 assertion depends on watchdog 2 (Tables 25 and 26).
1 = PO6/PO4 assertion depends on IN1 secondary undervoltage/overvoltage threshold (Table 2).
1 = PO6/PO4 assertion depends on IN2 secondary undervoltage/overvoltage threshold (Table 3).
1 = PO6/PO4 assertion depends on IN3 secondary undervoltage/overvoltage threshold (Table 4).
1 = PO6/PO4 assertion depends on IN4 secondary undervoltage/overvoltage threshold (Table 4).
1 = PO6 (MAX6872 only) assertion depends on IN5 secondary undervoltage/overvoltage
threshold (Table 4). Must be set to 0 for the MAX6873.
1 = PO6 (MAX6872 only) assertion depends on IN6 secondary undervoltage/overvoltage
threshold (Table 4). Must be set to 0 for the MAX6873.
1 = PO6/PO4 assertion depends on GPI1 (Table 5).
1 = PO6/PO4 assertion depends on GPI2 (Table 5).
1 = PO6/PO4 assertion depends on GPI3 (Table 5).
1 = PO6/PO4 assertion depends on GPI4 (Table 5).
1 = PO6 (MAX6872 only) assertion depends on PO1 (Table 8). Must be set to 0 for the MAX6873.
1 = PO6 (MAX6872 only) assertion depends on PO2 (Table 9). Must be set to 0 for the MAX6873.
1 = PO6/PO4 assertion depends on PO3 (MAX6872)/PO1 (MAX6873) (Tables 10 and 11).
1 = PO6/PO4 assertion depends on PO4 (MAX6872)/PO2 (MAX6873) (Tables 12 and 13).
1 = PO6/PO4 assertion depends on PO5 (MAX6872)/PO3 (MAX6873) (Tables 14 and 15).
1 = PO6/PO4 assertion depends on PO7 (MAX6872)/PO5 (MAX6873) (Table 18).
1 = PO6 (MAX6872 only) assertion depends on PO8 (Table 19). Must be set to 0 for the MAX6873.
1 = PO6/PO4 asserts when MR = low (Table 6).
T able 16 only applies to PO6 of the MAX6872 and PO4
of the MAX6873. Write a 0 to a bit to make the PO6/PO4
output independent of the respective signal (IN_ primary
or secondary thresholds, WD1 or WD2, GPI1–GPI4, MR ,
or other programmable outputs). See Table 17 for
Product 2. PO6 (MAX6872)/PO4 (MAX6873) deasserts
when Product 1 or Product 2 = 1.
