Low-Voltage, SOT23 μP Supervisors with Power-
Fail In/Out, Manual Reset, and Watchdog Timer
General Description
The MAX6701–MAX6708 microprocessor (μP) supervisory
circuits reduce the complexity and components required
to monitor power-supply functions in μP systems. These
devices significantly improve system reliability and accu-
racy compared to separate ICs or discrete components.
The MAX6701–MAX6708 family provides four functions:
a reset output during power-up, power-down, and
brownout conditions; an independent watchdog output
that goes low if the watchdog input has not been toggled
within 1.6s; a 0.62V threshold detector for power-fail
warning; and an active-low manual reset input.
The MAX6701–MAX6708 family offers several pinout
options to accommodate a variety of multivoltage micro-
processor supervision applications.
The MAX6701(A)/MAX6702(A)/MAX6703(A) monitor
three supply voltages (one fixed threshold and two
adjustable) to drive a single reset output and include a
manual reset input and a watchdog timer with an inde-
pendent output. The MAX6704 monitors a single-supply
voltage to drive complementary reset outputs and
includes an independent adjustable power-fail-in/power-
fail-out comparator, a manual reset input, and a reset-
based watchdog timer. The MAX6705(A)/MAX6706(A)/
MAX6707(A) monitor a single-supply voltage to drive a
single reset output and include an independent
adjustable power-fail-in/power-fail-out comparator, a

pendent output. The MAX6708 is the same as the
MAX6704 but without the watchdog timer function.

Insert the desired suffix letter (from the Threshold Suffix Guide
table) into the blank to complete the part number. All devices
must be ordered in increments of 2500 pieces. Sample stock is
typically held on standard versions only. Contact factory for
availability.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
