OUTPUT ASSERTION CONDITIONS

1 = PO2 assertion depends on IN1 undervoltage threshold (Table 2).

1 = PO2 assertion depends on IN2 undervoltage threshold (Table 3).

1 = PO2 assertion depends on IN3 undervoltage threshold (Table 4).

1 = PO2 assertion depends on IN4 undervoltage threshold (Table 4).

1 = PO2 assertion depends on IN5 undervoltage threshold (Table 4).

1 = PO2 assertion depends on IN6 undervoltage threshold (Table 4).

1 = PO2 assertion depends on watchdog (Tables 18 and 19).

Must be set to 0.

Must be set to 0.

1 = PO2 assertion depends on GPI1 (Table 5).

1 = PO2 assertion depends on GPI2 (Table 5).

1 = PO2 assertion depends on GPI3 (Table 5).

1 = PO2 assertion depends on GPI4 (Table 5).

1 = PO2 assertion depends on PO1 (Table 7).

1 = PO2 assertion depends on PO3 (Table 9).

1 = PO2 assertion depends on PO4 (Table 10).

1 = PO2 assertion depends on PO5 (Table 11).

1 = PO2 assertion depends on PO6 (Table 12).

1 = PO2 assertion depends on PO7 (Table 13).

1 = PO2 assertion depends on PO8 (Table 14).

1 = PO2 asserts when MR = low (Table 6).

Table 8 only applies to PO2 of the MAX6874. Write a 0

to a bit to make the PO2 output independent of the

respective signal (IN1–IN6 thresholds, WD, GPI1–GPI4,

MR, or other programmable outputs).
