General Description
The MAX6715A–MAX6729A are ultra-low-voltage micro-
processor (P) 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 maintain reset
for a minimum timeout period after all supplies rise above
their thresholds. The integrated dual/triple supervisory cir-
cuits significantly improve system reliability and reduce size
compared to separate ICs or discrete components.
from 1.8V to 5.0V and secondary supply voltages (VCC2)
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 VCC1 or VCC2
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 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 VTH1 =
4.625V, VTH2 = 3.075V, and 210ms (typ) timeout period.
