MAX6715A–MAX6729A/
MAX6797A
Dual/Triple, Ultra-Low-Voltage, SOT23 μP
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note that a “+”, “#”, or “-” in the package
code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board. For detailed information on
