4-Pin SC70 Microprocessor Reset Circuits
with Manual Reset Input
General Description
The MAX6711/MAX6712/MAX6713 are microprocessor
(µP) supervisory circuits used to monitor the power
supplies in µP and digital systems. They provide excel-
lent circuit reliability and low cost by eliminating exter-
nal components and adjustments when used with
+5.0V, +3.3V, +3.0V, or +2.5V-powered circuits. They
also provide a debounced manual reset input.
These circuits assert a reset signal whenever the V
CC
supply voltage declines below a preset threshold or
whenever manual reset is asserted. Reset remains
asserted for at least 140ms after V
CC
has risen above
the reset threshold or when manual reset is deasserted.
Reset thresholds suitable for operation with a variety of
supply voltages are available.
The MAX6713 has an open-drain output stage, while
the MAX6711/MAX6712 have push-pull outputs. The
MAX6713’s open-drain
RESET
output requires a pull-up
resistor that can be connected to a voltage higher than
V
CC
. The MAX6711/MAX6713 have an active-low reset
output, while the MAX6712 has an active-high reset out-
put. The reset comparator is designed to ignore fast
transients on V
CC
, and the outputs are guaranteed to
be in the correct logic state for V
CC
down to 1V.
Low supply current makes the MAX6711/MAX6712/
MAX6713 ideal for use in portable equipment. These
devices are available in a 4-pin SC70 package.
