Detailed Description
Supply Voltages
The MAX6715
–
MAX6729 microprocessor (μP) supervi-
sory circuits maintain system integrity by alerting the μP
to fault conditions. These ICs are optimized for systems
that monitor two or three supply voltages. The output-
reset state is guaranteed to remain valid while either
V
CC
1 or V
CC
2 is above 0.8V.
Threshold Levels
Input voltage threshold level combinations are indicat-
ed by a two-letter code in the
Reset Voltage Threshold
Suffix Guide
(Table 1). Contact factory for availability of
other voltage threshold combinations.
Reset Outputs
The MAX6715
–
MAX6729 provides an active-low reset
output (
RST
) and the MAX6725/MAX6726 provides
both an active-high (RST) and an active-low reset out-
put (
RST
). RST,
RST
,
RST1
, and
RST2
are asserted
when the voltage at either V
CC
1 or V
CC
2 falls below the
voltage threshold level, RSTIN drops below threshold,
or
MR
is pulled low. Once reset is asserted it stays low
for the reset timeout period (see Table 2). If V
CC
1,
V
CC
2, or RSTIN goes below the reset threshold before
the reset timeout period is completed, the internal timer

PFO
Active-Low Power-Fail
Monitor Output, Open-
Drain or Push-Pull.
PFO
is
asserted low when PFI is
less than 0.626V.
PFO
deasserts without a reset
timeout period. Open-
drain outputs require an
external pullup resistor.
Push-pull outputs are
referenced to V
CC
1.
Active-High Reset
Output, Open-Drain or
Push-Pull. RST changes
from low to high when
V
CC
1 or V
CC
2 drops
below selected reset
thresholds, RSTIN is
below threshold,
MR
is
pulled low, or the
watchdog triggers a
reset. RST remains HIGH
for the reset timeout
period after V
CC
1/
V
CC
2/RSTIN exceed the
device reset thresholds,
MR
goes low to high, or
the watchdog triggers a
reset. Open-drain outputs
require an external pullup
resistor. Push-pull
outputs are referenced to
V
CC
1.
