OUTPUT ASSERTION CONDITIONS
1 = PO1 assertion depends on IN1 undervoltage threshold (Table 2)
1 = PO1 assertion depends on IN2 undervoltage threshold (Table 3)
1 = PO1 assertion depends on IN3 undervoltage threshold (Table 3)
1 = PO1 assertion depends on IN4 undervoltage threshold (Table 3)
1 = PO1 assertion depends on IN5 (MAX6889/MAX6890 only) undervoltage threshold
(Table 3)
1 = PO1 assertion depends on IN6 (MAX6889/MAX6890 only) undervoltage threshold
(Table 3)
1 = PO1 assertion depends on IN7 (MAX6890 only) undervoltage threshold (Table 3)
1 = PO1 assertion depends on IN8 (MAX6890 only) undervoltage threshold (Table 4)
1 = PO1 assertion depends on watchdog (Table 20)
1 = PO1 assertion depends on GPI1 (Table 5)
1 = PO1 assertion depends on GPI2 (Table 5)
1 = PO1 assertion depends on GPI3 (Table 5)
1 = PO1 assertion depends on GPI4 (MAX6889/MAX6890 only) (Table 5)
1 = PO1 asserts when MR = low (Table 6)
Not used
Note: Table 7 only applies to PO1. Write a “0” to a bit to make the PO1 output independent of the respective signal (IN_ thresholds,
WD, GPI_, or MR ).
