Using the MAX6842/MAX6845 Open-Drain
RESET
Output with Multiple Supplies
Generally, the pullup connected to the MAX6842/
MAX6845 connects to the supply voltage being moni-
tored at the IC
’
s V
CC
pin. However, some systems use
the open-drain output to level-shift from the monitored
supply to reset circuitry powered by some other supply
(Figure 5). Note that as the MAX6842/MAX6845
’
s V
CC
decreases, so does the IC

. Also, with any pullup,
RESET
is pulled high as
V
CC
decays toward 0. The voltage where this occurs
depends on the pullup resistor value and the voltage to
which it is connected.
