NAME
FUNCTION
1
—
Active-Low Push-Pull or Open-Drain Output.
RESET
changes from high to low when
V
CC
or RSTIN drops below its selected reset threshold.
RESET
remains low for the
140ms (min) reset timeout period after all monitored power-supply inputs exceed their
selected reset thresholds.
MR
does not affect
RESET
output. For open-drain outputs,
connect to an external pullup resistor.

RESET
Active-Low Push-Pull or Open-Drain Output.
RESET
changes from high to low when
V
CC
or RSTIN drops below its selected reset threshold.
RESET
remains low for the
140ms (min) reset timeout period after all monitored power-supply inputs exceed their
selected reset thresholds.
RESET
changes from high to low after
MR
input is held low
for the 3.36s (typ) setup period and deasserts 140ms (min) after
MR
deasserts. For
open-drain outputs, connect to an external pullup resistor.

MROUT
Manual Reset Push-Pull or Open-Drain Output.
MROUT
asserts immediately after
MR
is
pulled low.
MROUT
remains low for 140ms (min) after
MR
is deasserted. For open-
drain outputs, connect to an external pullup resistor.

CC
Voltage Input. Power supply and input for the primary microprocessor voltage
reset monitor.

RSTIN
Reset Input. High-impedance input to the adjustable reset comparator. Connect RSTIN
to the center point of an external resistor divider to set the threshold of the externally
monitored voltage.
