Supervisory Circuits
General Description
The MAX6715A–MAX6729A/MAX6797A are ultra-low-
voltage microprocessor (μP) supervisory circuits designed to
monitor two or three system power-supply voltages. These
devices assert a system reset if any monitored supply falls
below its factory-trimmed or adjustable threshold and main-
tain reset for a minimum timeout period after all supplies rise
above their thresholds. The integrated dual/triple superviso-
ry circuits significantly improve system reliability and reduce
size compared to separate ICs or discrete components.
These devices monitor primary supply voltages (V
CC1
)
from 1.8V to 5.0V and secondary supply voltages (V
CC
2)
from 0.9V to 3.3V with factory-trimmed reset threshold
voltage options (see the
Reset Voltage Threshold Suffix
Guide).
An externally adjustable RSTIN input option
allows customers to monitor a third supply voltage down
to 0.62V. These devices are guaranteed to be in the cor-
rect reset output logic state when either V
CC1
or V
CC2
remains greater than 0.8V.
A variety of push-pull or open-drain reset outputs along
with watchdog input, manual-reset input, and power-fail
input/output features are available (see the Selector
Guide). Select reset timeout periods from 1.1ms to
1120ms (min) (see the
Reset Timeout Period Suffix
Guide).
The MAX6715A–MAX6729A/MAX6797A are
available in small 5-, 6-, and 8-pin SOT23 packages and
operate over the -40°C to +125°C temperature range.

Note:
The first “_ _” are placeholders for the threshold voltage
levels of the devices. Desired threshold levels are set by the part
number suffix found in the Reset Voltage Threshold Suffix Guide.
The “_” after the D is a placeholder for the reset timeout delay
time. Desired delay time is set using the timeout period suffix
found in the Reset Timeout Period Suffix Guide. For example,
the MAX6716AUTLTD3-T is a dual-voltage supervisor V
