General Description
The MAX6701–MAX6708 microprocessor (P) supervisory
circuits reduce the complexity and components required
to monitor power-supply functions in P 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
manual reset input, and a watchdog timer with an inde-
pendent output. The MAX6708 is the same as the
MAX6704 but without the watchdog timer function.
See the Detailed Description for differences between
non-A and A versions.
