_______________General Desc ription
The MAX809/MAX810 are microprocessor (μP) supervi-
sory circuits used to monitor the power supplies in μP
and digital systems. They provide excellent circuit reli-
ability and low cost by eliminating external components
and adjustments when used with 5V-powered or 3V-
powered circuits.
These circuits perform a single function: They assert a
reset signal whenever the V
CC
supply voltage declines
below a preset threshold, keeping it asserted for at least
140ms after V
CC
has risen above the reset threshold.
The only difference between the two devices is that the
MAX809 has an active-low
RESET
output (which is guar-
anteed to be in the correct state for V
CC
down to 1V),
while the MAX810 has an active-high RESET output.
The reset comparator is designed to ignore fast tran-
sients on V
CC
. Reset thresholds suitable for operation
with a variety of supply voltages are available.
Low supply current makes the MAX809/MAX810 ideal
for use in portable equipment. The MAX809/MAX810
come in a 3-pin SOT23 package.
