Table 19 only applies to PO8 of the MAX6872. Write a 0
to a bit to make the PO8 output independent of the
respective signal (IN1–IN6 primary or secondary
thresholds, WD1 or WD2, GPI1–GPI4, MR, or other pro-
grammable outputs).
Output Stage Configurations
Independently program each programmable output as
active high or active low (Table 20). Additionally, pro-
gram each programmable output as weak pullup, push-
pull, open-drain, or charge pump (Tables 21 and 22).
Every programmable output can be configured as
open-drain or weak pullup; however, only PO1–PO4
(MAX6872) or PO1–PO2 (MAX6873) can be configured
as charge-pump outputs, and only PO5–PO8
(MAX6872) or PO3–PO5 (MAX6873) can be configured
as push-pull outputs. Finally, set the PO_ timeout period
for each programmable output (Table 23).
An internal 10k
resistor provides the pullup resistance
for outputs configured as weak pullup stages. Program
each weak pullup output stage to refer to ABP or one of
the IN3–IN6 inputs. The programmable outputs source up
to 10mA and sink up to 4mA when configured as push-
pull stages. Program each push-pull output stage to ref-
erence to one of IN3–IN6. PO1–PO4 (MAX6872)/
PO1–PO2 (MAX6873) pull to VABP + 5V when configured
as charge-pump outputs.
