age threshold, and the states of GPI2 and WD1. Write
ones to R19h[6, 0] and R1Ah[7] to configure Product 2
as indicated. IN1 must be above the primary undervolt-
age threshold (Table 2), GPI2 must be inactive (Table
5), and the WD1 timer must not have expired (Tables 25
and 26) for Product 2 to be a logical 1. Product 2 is
equivalent to the logic statement: V1A
GPI2 WD1.
PO3 deasserts if either Product 1 or Product 2 is a logi-
cal 1. The logical statement: Product 1 + Product 2
determines the state of PO3.
Table 8 only applies to PO1 of the MAX6872. Write a 0
to a bit to make the PO1 output independent of the
respective signal (IN1–IN6 primary or secondary
thresholds, WD1 or WD2, GPI1–GPI4, MR, or other pro-
grammable outputs).
Table 9 only applies to PO2 of the MAX6872. Write a 0
to a bit to make the PO2 output independent of the
respective signal (IN1–IN6 primary or secondary
thresholds, WD1 or WD2, GPI1–GPI4, MR, or other pro-
grammable outputs).
