General Description
The MAX6701–MAX6708 microprocessor (P) superviso-
ry circuits reduce the complexity and components
required to monitor power-supply functions in P sys-
tems. These devices significantly improve system reliabil-
ity and accuracy 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/MAX6702/MAX6703 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 independent output. The
MAX6704 monitors a single supply voltage to drive com-
plementary 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/MAX6706/MAX6707 monitor a single sup-
ply voltage to drive a single reset output and include an
independent adjustable power fail in/power fail out com-
parator, a manual reset input, and a watchdog timer with
an independent output. The MAX6708 is the same as the
MAX6704 but without the watchdog timer function.
